Safety Instructions

DCS 500B / DCP 500B Operating Instructions i

Overview This chapter contains safety instructions which must be complied

with during installation, operation and maintenance of the power

converters series DCS 500B / DCF 500B or DCP 500B. If these in-

structions are not complied with, this may result in injuries (perhaps

even with fatal) or in damage to the power converter, the motor and

the driven machine. Before starting with any work whatsoever at or

with this unit, you must read the information given in this chapter.

Warnings Warnings provide information on states which if the specified pro-

cedure for the state concerned is not meticulously complied with

may result in a serious error, in major damage to the unit, in injury

to persons and even in death.

They are identified by the following symbols:

Danger: High Voltage! This symbol warns you of

high voltages which may result in injuries to persons

and/or damage to equipment. Where appropriate, the

text printed adjacent to this symbol describes how

risks of this kind may be avoided.

● All electrical installation and maintenance work on the thyristor

power converter must be carried out by properly qualified staff

who have been thoroughly trained in electrical engineering.

● The thyristor power converter and its adjacent units must be

properly earthed by qualified professionals.

● You must NEVER perform any work on the thyristor power con-

verter while it is still switched on. First switch the unit off, use a

measuring instrument to make absolutely sure that the power

converter has really been de-energized, and only then you may

start with the work concerned.

● Due to external control circuits, there may be dangerously high

voltages present at the thyristor power converter even after the

line voltage has been switched off. So always work at the unit

with appropriate caution! Non-compliance with these instructions

may result in injury (or even death!).

3ADW000055R0401_DCS500B_Operating Instruction_e_d

Safety Instructions

ii DCS 500B / DCP 500B Operating Instructions

General warning: this symbol warns you of non-

electrical risks and dangers which may result in seri-

ous or even fatal injury to persons and/or in damage

to equipment. Where appropriate, the text printed ad-

jacent to this symbol describes how risks of this kind

may be avoided.

● When thyristor power converters are in use, the electric motors,

power transmission elements and the driven machines are work-

ing in an extended operating range, which means they have to

cope with a relatively high loading.

● You should have made sure that all units, devices and appli-

ances used are actually suitable for this higher loading.

● If you have to operate the thyristor power converter at a rated

motor voltage and/or a rated motor current significantly below

the figures stated in the thyristor power converter's output data,

you must take appropriate precautionary measures to protect the

unit against overspeed, overload, breakage, etc., by modifying

the software or hardware appropriately.

● For insulation testing, you must disconnect all cables from the

thyristor power converter. You should avoid operating your unit

at values other than the rated data. Non-compliance with these

instructions may cause lasting damage to the thyristor power

converter.

● The thyristor power converter possesses a number of automatic

reset functions. When these functions are executed, the unit will

be reset after an error and will then resume operation. These

functions should not be used if other units and devices are not

suitable for an operating mode of this kind, or if their use might

entail dangerous situations.

Warning of electrostatic discharge:

this symbol warns you against electrostatic discharges

which may damage the unit. Where appropriate, the

text printed next to this symbol describes how a risk of

this kind may be avoided.

Notes Notes supply information on states requiring particular attention, or

indicate that additional information is available on a specific topic.

For this purpose, the following symbols are used:

CAUTION! Cautions are designed to draw your attention to a

particular state of affairs.

Note A note contains or refers you to additional informa-

tion available on the particular topic concerned.

Mains connection You can use a switch disconnector (with fuses) in the power supply

of the thyristor power converter to disconnect the electrical compo-

nents of the unit from the power supply for installation and mainte-

nance work. The type of disconnector used must be a switch dis-

connector as per EN 60947-3, Class B, so as to comply with EU

regulations, or a circuit-breaker type which switches off the load cir-

cuit by means of an auxiliary contact causing the breaker's main

contacts to open. The mains disconnector must be locked in its

"OPEN" position during any installation and maintenance work.

EMERGENCY STOP

buttons

EMERGENCY STOP buttons must be installed at each control desk

and at all other control panels requiring an emergency stop func-

tion. Pressing the STOP button on the CDP 31x control panel of the

thyristor power converter will neither cause an emergency motor

stop, nor will the drive be disconnected from any dangerous poten-

tial.

Intended use The operating instructions cannot take into consideration every

possible case of configuration, operation or maintenance. Thus,

they mainly give such advice only, which is required by qualified

personnel for normal operation of the machines and devices in

industrial installations.

If in special cases the electrical machines and devices are intended

for use in non-industrial installations - which may require stricter

safety regulations (e.g. protection against contact by

children or similar) -, these additional safety measures for the instal-

lation must be provided by the customer during assembly.

Incoming inspection After opening this package, you should check whether it contains

the following items:

● DCS 500B / DCF 500B or DCP 500B thyristor power con-

verter in the configuration ordered

● DCS 500B / DCF 500B or DCP 500B publications

● Accessories, including manuals if ordered

● Final test report

Check the consignment for any signs of damage. If you find any,

please contact the insurance company or the supplier.

Check the particulars given on the unit's rating plate to make sure

prior to installation and start-up that you have received the correct

unit type and unit version.

If the consignment is incomplete or contains any incorrect items,

please contact the supplier.

CAUTION! The thyristor power converter weighs quite a lot and

should therefore not be held by the front cover. Please put the unit

down only on its back (sizes C1/C2/A5). Always use care when

handling the unit, so as to avoid injuries or damage.

Storage and transport If the unit had been in storage prior to installation or is transported

to another location, care must be taken to ensure that the environ-

mental conditions are complied with (see "System Descriptions

DCS 500B / DCF 500B or DCP 500B").

Rating plate

For purposes of identification, each thyristor power converter is fit-

ted with rating plates, stating the type code and the serial number,

which serve for each unit's individual identification.

The type code contains information on the characteristics and the

configuration of the unit. The first three digits of the serial number

refer to the year and week of manufacture. The last digits complete

the serial number so as to preclude two units receiving the same

type code and the same serial number.

The 112xx group provides information on the unit's software con-

figuration.

The technical data and specifications are valid as of going to press.

ABB reserves the right to make subsequent alterations.

If you have any questions concerning your drive system, please

contact your local ABB agent.

General notes

CAUTION: it is absolutely essential that the applicable accident prevention

regulations be observed by the user (in this context, please also

read the chapter entitled "Safety Instructions")!

How this chapter is structured

For better understanding the individual steps of start-up work are distinguished by

a) frames without any additional marking on the left side:

 These steps of start-up work must always be performed (= mandatory start-up work)!

Example:

522 = GERMAN [Only with the SDCS-CON-2 control board & the CDP 312 panel!]

Activates German texts on the display ...........

b) frames with marking on the left side („columns“ shaded in grey):

 These steps of start-up work have to be performed only when the condition stated

(as heading) applies to the selected drive configuration! After this work has been

completed, the

mandatory start-up work has to be continued.

Example:

Only when connection diagram 1 (Appendix A) is being used!

906 = 12502

Function „EMERGENCY STOP“ de-activated ............

Recommended motor voltages and field voltages

• Motor voltage UA when the following units are used

DCS 501B / DCP 501B: UAmax = Line voltage * 1.16 (2- quadrant unit)

DCS 502B / DCP 502B: UAmax = Line voltage * 1.05 (4- quadrant unit)

• Field voltage UF (= max. output voltage) when the following is being used

SDCS-FEX-1: UF = Line voltage * 0.9

If there is a divergence of more than 10 % between the field supply unit's output

voltage and the rated field voltage UFrated stated on the motor's rating plate, then the

connecting voltage UN should be reduced, using a matching transformer or a series

resistor Rv: R

v = (0.9 * UN - UF) / IF IF = Rated field current

(Note: also suitable for fine-balancing the maximum motor voltage)

• Field voltage UF when the following is being used

SDCS-FEX-2 /

DCF 503 / DCF 504: UF = Line voltage * 0.6 ... 0.8

• Field voltage UF when the following is being used

DCF 501B / DCF 502B: UF = Line voltage * 0.5 ... 1.1

Maximally possible output voltage UAmax using

DCF 501B / DCF 502B: UF = Line voltage * 1.35

Chapter 2 - Start-Up Instructions

IV A 2 - 2 DCS 500B / DCP 500B Operating Instructions

Phase sequence when connecting to the mains / Potential isolation

No special phase sequence required for the main connections U1, V1 and W1!

Phase coordination between electronics section and power section not necessary!

For potential isolation and for avoiding ground loops, an isolating transformer should be

installed upstream when an oscilloscope is being used.

Preventing unintended operating states / Shutting the drive down

CAUTION! As laid down in DIN 57100 Part 727 / VDE 0100 Part 727 (Preventing

unintended operating states), shutting the drive down by means of the

signals at the binary inputs DIx is not sufficient in itself as the sole

measure involved for avoiding unintended operating states or shutting

the drive down in the event of danger!

Range of application for the Start-Up Instructions

The Start-Up Instructions are referenced to the parameter settings in their as-delivered

condition (default values) and to the unit wiring as shown in connection diagram 1 or 2

(see Appendix A). In both circuit variants, the binary inputs DI5, DI7 and DI8 can be used.

They will cause the reactions at the drive as described below.

The symbols stated in this context will be repeatedly used further on in the text.

Method of functioning of the binary inputs DI5, DI7 and DI8

• Binary input DI5; designation EM STOP

In operation, DI5 must be set to logical "1“. If it is set to "0“, the alarm signal A 102

will appear. The drive will react in accordance with the function set at Parameter 917

(shutdown with ramp, with torque limit/current limit, with controller blocking and

coasting). Once ramp-down has been completed (speed feedback below nmin), the

output is reset for controlling the line contactor. After that, the EM STOP input

should be set back to "1“, the alarm message acknowledged, and the ON/OFF input

likewise be set to "0“. After that, the drive can be started anew.

• Binary input DI7; designation ON/OFF

For connecting the drive to the mains, DI7 must be set to logical "1“. If there are no

ongoing faults, the outputs for controlling the contactors for the armature circuit and

the field circuit will be activated. If DI7 is set to "0“, the controllers will be blocked in-

ternally and the outputs reset after a time-delay.

The function which can be set with Parameter 915 (inputs DI7 and DI8 for switching

the contactors) will only be operative when the drive has been wired as shown

in connection diagram 2.

- Switch OFF power

X6: 7 ⇒ „0“ signal

(K20 in connection example)

(input ON / OFF)

• Binary input DI8; designation RUN

For starting the drive, DI8 must be set to logical „1“. This enables the reference at the

REF_SEL and RAMP GENERATOR blocks, as well as the controllers. If DI8 is set to

"0“, the drive will react in accordance with the function set at Parameter 916 (shut-

down with ramp, with torque limit/current limit, with controller block and coasting).

Once ramp-down has been completed (speed feedback below nmin), the reference is

kept at zero, and the controllers blocked after a time-delay; the drive is torqueless.

Symbols for enabling / disabling the reference

- ENABLE reference X6: 8 ⇒ „1“ signal

(K21 in connection example) (input RUN)

- DISABLE reference X6: 8 ⇒ „0“ signal

(K21 in connection example)

(input RUN)

System-dependent planning

If you want the drive to react with a function other than that of Parameter 916 or 917, you

have to parameterize the unit accordingly, by connecting one of the inputs or an addi-

tional one with a control pin, e.g. at the ramp-function generator.

- Example 1:

Operational ramp-up and ramp-down in the event of reference changes with the same

ramp times, shutdown via RUN with a different time.

Solution:

use second parameter set ramp times; set time at DECEL2;

establish connection from P 1707 to P 10716.

- Example 2:

Implementing an EMERGENCY SHUTDOWN or EMERGENCY STOP function.

Solution:

this function stipulated in various regulations must always be planned in dependence on

the system involved! A basic distinction must be made here between electrical and me-

chanical risks. Since one signal at one input is not sufficient (see above), at least one

other switch-off option must be created, e.g. by means of a relay directly switch-

ing input DI5 to "0“. This is how the power converter attempts (in accordance with

P 917), to defuse the dangerous situation. A dropout-delay contact of the relay will

then switch the power off. If the delay is small or does not match the function selected

for P 917, then certain operating states (regeneration) may, due to laws of physics,

result in the unit fuses tripping, and in extreme cases in thyristor defects.

2.1 Preparatory work

Check the unit for damage in transit or other damage.

Install and wire unit; connect all inputs and outputs required.

Proceed in the same way for the field supply unit as well.

Check whether protective measures, earthing, screening, etc. have been taken in

accordance with the system conditions involved.

Check the rated value of the supply voltage for the electronics and the fan:

• matching transformer necessary when:

- electronics supply is not equal to 115 V/230 V

- single-phase-fan supply is not equal to 230 V

- three-phase-fan supply is not within the range of 400 V .... 690 V.

Check the rated value of the supply voltage for the armature-circuit converter's

power section; the particulars given on the rating plate must be > than the rated

line voltage.

If this condition is not satisfied, then the following applies:

- use an isolating transformer, or

- use a suitable unit.

Check the rated value of the supply voltage for the field supply unit.

(Particulars on rating plate > rated line voltage?

Is an auxiliary transformer or perhaps a series resistor necessary?)

Check the wiring, fusing, the cross-sectional areas of the cables.

Provide an option for switching binary inputs X6: 7 and X6: 8.

Check the system's EMERGENCY STOP for proper functioning! Set the system-side

monitoring functions, and activate them. Check whether auxiliaries, such as motor fans

or unit fans, function properly; while doing this, also check for correct direction of rota-

tion and voltage level as well!

2.3 Presetting the field supply unit

Make sure that existing supply voltages for power section, field supply unit (field ex-

citer) and field winding, fan, etc. match the rated data of the components used.

Switch ON power.

DANGER: System components now energized!

Please wait a few moments. During this time, the unit compares the phase sequence

set in the parameter with that obtaining at the power section.

If the unit outputs the "Phase sequence fault of power section“ signal (F 38):

- switch off unit completely and disconnect from the mains, interchange two phases at

the input, and start again from the beginning of this chapter.

- enter: 506 = R-T-S and then acknowledge fault signal.

Unit will automatically adapt to phase sequence; this signal is to be interpreted as in-

formation to the effect that the fans' direction of rotation may be wrong for size-C4

units.

DCS 500B / DCP 500B Operating Instructions IV A 3 - 1

3.1 Overview

The Control and Display Panel [Control Panel] is used for parame-

ter setting, for feedback value measuring and for drive control with

series DCS 500B / DCF 500B and DCP 500B thyristor power con-

verters. This device is available in different versions depending on

the type of unit and software to be used:

Units with software S 21.1xx ⇒ CDP 310 or CDP 311

(recommended: CDP 311)

Units with software S 21.2xx ⇒ CDP 312

Hereinafter CDP 31x will be used as a common type designation for

the above mentioned versions of Control Panel. Differences be-

tween the versions which have to be taken into account with par-

ticular functions will be indicated separately!

Panel Link

The CDP 310/311 Control Panel is connected to the drive via

CDI-300 communication bus.This communication bus, which is

based on the RS485 standard, is a common bus protocol for ABB

Drives products.

MODBUS is used as communication bus connecting the CDP 312

Control Panel to the drive. This Control Panel combined with a

Software version S 21.2xx onwards makes it possible to show the

texts on the LCD in different languages.

The selection of language is performed by parameter [P 522].

Note: The display texts as shown in this chapter correspond

to the default setting of [P 522] ( ⇒ English)!

Mounting the

Panel The CDP 31x Control Panel can be handled in three different ways:

• Direct mounting on the thyristor power converter; the CDP 31x is

plugged into the moulded part of the cover of the converter and

connected via an adaptor of approx. 45 mm.

• Mounting on the door of the switchgear cabinet using an assem-

bly kit equipped with a connection cable.

• Use of Panel as remote control device with a connection cable.

3.2 Start Mode Note: The CDP 31x can be connected to the drive without dis-

connecting the auxiliary power !

When connected and power is applied to the electronics, the dis-

play of the CDP 31x shows:

• The drive is not present on the link. This is the case if the drive

stops communicating.

• The link does not operate because of a hardware malfunction or

a cabling fault.

Action: Disconnect the

Parameter 11202:

If one or both of these functions have been performed additional ac-

be selected for saving the values to the backup memory, if a

DOWNLOAD had taken place.

UPLOAD will copy all parameters and connections, which are dif-

ferent to default, from the RAM memory of the drive to the FPROM

memory of the Control Panel CDP 31x.

Before a DOWNLOAD is started the factory-set values (default val-

ues) should be available within the drive´s RAM memory.

Factory-set values are always available in control board memory

and they can be called by means of BACKUPSTOREMODE pa-

rameter 11202 [FACTORY_SET_VALUE] or by means of S2 switch

on the control board SDCS-CON-x.

The DOWNLOAD will copy all values stored in the FPROM memory

of the CDP 31x to the RAM memory of the drive. Downloaded

parameters should be saved to the FPROM memory of the control

board SDCS-CON-x. See chapter 3.5"Saving of Parameters to

backup memory" .

Note: For reasons of safety the DOWNLOAD function will only

operate if „LOCAL mode“ of the Control Panel CDP 31x

is selected!

4.1 Display of status, alarm and fault signals

Categories of signals

and possibilities of

display

The signals (messages) to be available for thyristor power con-

verters series DCS 500B / DCF 500B or DCP 500 are subdivided

into five

categories:

General messages

Starting errors

F Fault signals

A Alarm signals

[112 . .] Status signals through parameters

A seven segment display on the control board SDCS-CON-x of the

thyristor power converters series DCS 500B / DCF 500B or

DCP 500 is used to show general messages, starting errors, fault

and alarm signals. The signals (messages) are displayed as codes.

If the codes consist of several parts, the characters/individual digits

will be indicated for 0.7 sec one after the other, e.g.:

0.7s 0.7s

0.7s

⇒⇒

F 14 = Speed measurement fault

⇑ ⇐ ⇓

In addition to this the DCS 500B DCF 500B or DCP 500 combined

with the LCD of the control panel CDP 31x will be able to show the

fault and alarm signals as well as the status signals (selected by

signal numbers [112 . .]) as clear text.

Note: The languages to be available for display as text depend

on the type of Control Panel and the Software version

( ⇒ Chapter „Handling of Control Panel CDP 31x“).

For subsequent evaluation via binary outputs or serial interfaces the

16 bit informations FAULT WORD1 [11101], FAULT WORD2 [11102]

and FAULT WORD3 [11103] as well as ALARM WORD1 [11104],

ALARM WORD2 [11105] and ALARM WORD3 [11106] contain several

fault and alarm signals as a binary code.

Each fault and alarm signal is coded as an individual error code to

the LATEST FAULT [11106] and LATEST ALARM [11107].

4.4 Fault Signals (F)

The fault signals will be shown on the seven segment display of the

control board SDCS-CON-x as codes F . . as well as on the LCD of

the control panel CDP 31x as clear text.

All fault signals - with the exception of F 17, F 18 and F 44 - can be

reset (after elimination of the faults); F 20 would be self resetting, if

the communication had been re-established before.

For resetting (RESET) of fault signals the following steps are re-

quired:

• Switching off the commands ON/OFF and RUN

• Elimination of the faults

• Fault acknowledgement, i.e. resetting (RESET)

a) as described for CDP 31x

or b) by short-time setting of the command RESET

to high (logical one) via a binary input

(default setting = DI6).

• Depending on the application conditions generate the commands

ON/OFF and RUN once more.

The fault signals will result in switching off the signal [10910] resp. in

stopping the drive (installation-dependent).

If a fault occurs, there will be three different possibilities of reaction (see

column “Remark” in the fault list):

(1) Fault will switch off the signals energizing the main contactor, the field

contactor and the fan contactor.

(2) Fault will switch off the signals energizing the main contactor and the

field contactor.

(3) Fault will switch off at least the signal energizing the main contactor.
