Functions
Current
Reduction
Reduce power consumption and heat generation by
limiting motor running current to 100%, 90%, or 80%
of maximum. Current should be increased to 120% if
microstepping.
(Torque is reduced/increased by the same %.)
Idle Current
Reduction
Reduce power consumption and heat generation by
limiting motor idle current to 90% or 50% of running
current. (Holding torque is reduced by the same %.)
Load Inertia
Anti-resonance and damping feature improve motor
performance. Set motor and load inertia range to 0–4x
or 5–10x.
Step
Resolution
For smoother motion and more precise speed, set the
pulse step resolution to 20000, 12800, 5000, 2000, 400
smooth, 400, 200 smooth, or 200 steps/rev.
Self Test
Automatically rotate the motor back and forth two turns
in each direction in order to confirm that the motor is
operational.
Drive Cooling Method Natural convection (mount drive to metal surface)
Mounting Use (2) #6 screws to mount wide or narrow side to metal
surface
Removable Connectors
Motor & Power Supply:
screw terminal blocks Phoenix Contact 1757051
Signals:
screw terminal blocks Phoenix Contact 1803633
Weight 10.8 oz [306g] – (including mating connectors)
Operating Temperature 0–85 °C [32–185 °F] – (interior of electronics section)
Ambient Temperature 0–50 °C [32–122 °F]
– (drive must be mounted to suitable heat sink)
Humidity maximum 90% non-condensing
Agency Approvals CE (EMC & LVD); RoHS
MOUNTING THE DRIVE
The STP-DRV-6575 drive can be mounted on the wide or the
narrow side of the chassis using (2) #6 screws. Fasten the drive
securely to a smooth, flat, metal surface that will help conduct
heat away from the chassis. Otherwise, forced air flow from a fan
may be required to prevent overheating. WARNING:
• Never mount the drive in a space where there is no air flow, or
where other devices can heat the surrounding air to 50°C [122°F].
• Never put the drive where it can get wet, or where metal or other
electrically-conductive particles can get on the circuitry.
• Always provide air flow around the drive. Minimum allowable
spacing between multiple drives is 0.5 in [13 mm].

TYPICAL WIRING DIAGRAM
CONNECTING THE POWER SUPPLY
STP-PWR-48xx or STP-PWR-3204 power supplies from
AutomationDirect are good choices to power the step-motor drive.
If the power supply you choose does not have a fuse on the
output, you will need to install a fast-acting 7A fuse on the “+”
power supply lead.
WARNING: Do not to reverse the polarity from the power supply
to the drive. Reverse connection will destroy your drive and void
the warranty.
CONNECTING THE MOTOR
WARNING: When connecting a step motor to the STP-DRV-6575
drive, be sure that the motor power supply is switched off. When
using a motor not supplied by AutomationDirect, secure any
unused motor leads so that they can’t short out. Never discon-
nect the motor while the drive is powered up. Never connect the
motor leads to ground or directly to the power supply. (See
Typical Wiring Diagram on the back side of this data sheet for the
step motor lead color code of AutomationDirect-supplied motors.
CONNECTING THE INPUT SIGNALS
The STP-DRV-6575 drive has three inputs:
• STEP: a high speed digital input for step pulse commands;
5–24 VDC logic
• DIR: a high speed digital input for the direction signal;
5–24 VDC logic
• EN: a 5-24V input for commanding the removal of power from the
motor; also clears faults and re-enables the motor in the case of
drive faults, e.g. over-current/short-circuit faults
Note: STEP and DIR inputs can be converted to STEP CW and STEP CCW by
moving the internal jumper S3.

• Connect the green ground screw to earth ground
• Use 18 or 20 AWG wire.
