What Is a Step Motor Driver?

A step motor driver is a device that takes input signals (usually Clock and Direction) and translates this

information into phase currents in the motor. Each time the step motor driver receives a pulse, the step

motor moves one step. If the driver receives 200 pulses, the motor moves 200 steps. The motor steps at

the same frequency as the clock pulses.

FIGURE 1: Step Motor Driver

General Description

The BLHV is a step motor driver that can drive motors rated from 1 to 7 amps/phase (unipolar rating). It

can handle 6-lead and 8-lead motors. This driver features a unipolar bilevel (or dual voltage) drive tech-

nique with short and open circuit protection (with a Fault LED and Fault Output).

Bilevel Drive

The basic function of a motor driver is to provide the rated motor phase current to the motor windings in

the shortest possible time. The bilevel driver uses a high voltage to get a rapid rate of current rise in the

motor windings in the least amount of time. When reaching the preset trip current, the driver turns off the

high voltage and sustains the current from the low voltage supply.

Half-Step/Full-Step

Users have a choice of full-step operation or half-step operation. Full-step operation occurs by energizing

two phases at a time, rotating a typical motor 1.8 degrees per step. Half-step operation occurs by alter-

nately energizing one, and then two, phases at a time, rotating the motor 0.9 degrees per step. Full-step

operation is suggested for applications that specifically require that mode, such as when retrofitting exist-

ing full-step systems.

Clock Modes

The BLHV has two clock options: Clock and Direction, or Dual Clock operation. Jumper JP2 is used to

select the clock option. Basically JP2 selects Terminal 5 as either the Direction input or the CCW input.

With the Clock and Direction option (most common option), clock pulses applied to the Clock input (Ter-

minal 6) cause the motor to step. The direction of the motor is determined by the logic level of the Direction

input (Terminal 5). Jumper JP2 must be in the “2-3” position for this mode (see Figure 4 and Table 1).

With the Dual Clock option, clock pulses applied to the Clock input (Terminal 6) cause the motor to step in

the clockwise direction. Clock pulses applied to the CCW input (Terminal 5) cause the motor to step in the

counterclockwise direction. Jumper JP2 must be in the “1-2” position for this mode.

Either positive or negative going pulses may be used by setting jumper JP1 in the appropriate position

(see Table 1). To determine which setting to use, first consider the type of clock pulse output on the pulse

generator or indexer (controller). If the clock output on the controller is open-collector type (sinking), then

use the negative going jumper setting (JP2 must be in the “1-2” position). If the clock output on the

controller is a pnp or p-channel (sourcing) type, then use the positive going jumper setting (JP2 must be

in the “2-3” position). If the clock output on the controller is a TTL/CMOS type (totem pole), then either

setting will work; but the jumper setting should be chosen based on the level of the clock output when the

controller is not pulsing. If the clock is low when not pulsing then use positive going jumper settings. If the

clock is high when not pulsing then use negative going jumper setting.

The clock inputs (Clock and CCW) are pulled up to +5VDC through a 10K ohm resistor for negative going

clock inputs; they are pulled down to 0VDC through a 10K ohm resistor for positive going clock inputs. The

pullups/pulldowns are followed by an RC filter. See Figure 2 and Figure 3.

Adjusting Kick Current

By following the silkscreen instructions on the cover, use a small screwdriver to adjust the potentiometer.

Line up the potentiometer’s arrow to the number corresponding to the motors rated current (amps/phase).

Motor Connections

Figure 5 is a hookup diagram for typical BLHV driver applications.

Input connections must be separated

from motor connections and all other possible sources of interference.

IMPORTANT NOTE: If the motor cable between the driver and the step motor extends beyond 25 feet,

consult the factory.

Fault Protection

There are 2 types of fault detection. When a fault is detected, the driver turns off the motor current, pulls

the Fault Out output low (0V), and the red Fault LED indicates which type of fault occurred. See the

Troubleshooting section for more information.

If the driver goes into a fault condition, the fault may be reset by turning the power OFF for at least 15

seconds or by pulling the RESET FAULT input (terminal 4) to a logic “0” for at least 100ms.

Table 2: Fault LED

Motor ON/OFF Input

The motor on/off input allows de-energizing a motor without disturbing the positioning logic. After re-

energizing the motor, a routine can continue. This reduces motor heating and conserves power, espe-

cially in applications where motors are stopped for long periods and no holding torque is required. If

holding torque is required (such as when lifting a load vertically), then the motor must stay energized.

Troubleshooting

If a Fault occurs, reset the Fault by applying a logic “0” to the Reset Fault Input (terminal 4) for at least

100ms (or by cycling power OFF for at least 15 seconds). After resetting, try to run the motor again. If the

driver faults again then check the conditions listed below.

Is the LED blinking slowly? (once a second)

This indicates that the motor has a phase shorted or there is a short in the motor cable or wiring. Check

the motor and the wiring for shorts. If the driver continues to sense “shorts” after the motor and wiring are

determined to be accurate, then the output transistors should be checked (see below).

Is the LED blinking quickly? (three times a second)

This indicates that there is an open or intermittant connection in one of the motor wires. Check the motor

and the wiring for opens. Another condition that may cause this type of fault, is when a large motor is

ramped down too quickly so that it loses it’s positioning.

Checking Output Transistors

1. Set the multimeter to Diode Test

2. Place the RED meter lead on 0VDC (Terminal 7)

3. Touch the black meter lead to each phase (terminals 1, 2, 12, and 13)

4. Reading should be between 0.450V and 0.550V

5. If any readings are signifigantly less than 0.450V, then the unit has been damaged.

If a factory repair is required, contact Anaheim Automations for an RMA#.
