Applied Motion Products STRAC8 Stepper Drive User Guide
Requirements
To begin, make sure you have the following equipment
- A compatible stepper motor. Visit applied-motion.com to purchase one.
- A small flat blade screwdriver for tightening the connectors (included).
- An AC supply voltage, 90VAC – 240VAC volts single-phase.
- A source of pulse & direction signals
Step 1 -Wiring AC Power Supply
DO NOT apply power until all connections to the drive have been made.
Wire the drive to the AC power source.
Use the connector supplied with the drive and one of the ground terminals on
the drive to connect the AC supply
Use 16 AWG wire for Line (L) and Neutral (N). Use 14 AWG for Earth Ground (G).
Care should be taken when working with high voltages
Step 2 – Wiring the Motor
Connect the drive to the motor. If using a non Applied Motion Products’ motor, consult the motor specs for wiring information.
Step 3 – Select the Motor
Each position of the 16-bit rotary switch selects a different motor,
automatically setting the configuration parameters in the drive. The STRAC8
drive comes programmed with up to
16 typical motors as factory defaults. Drives can be customized with specially
selected motors when required. Available options are in the hardware manual.
Note: Motor current is limited by the lower value between rotary switch
setting and dip switches SW5 – SW8
If the motor selection is changed, the drive power supply will need to be
cycled.
For a custom motor, please select custom motor via the rotary switch, then use
the DIP switches to configure running current , anti-resonance and other
settings.

Step 5 – Self Test
The STRAC8 has a built in Self Test function. If switch 16 is moved to the ON
position the drive will automatically rotate the motor
back and forth, two turns in each direction. This feature can be used to
confirm that the motor is correctly wired, selected and otherwise operational.
A full user manual for the STRAC8 is available for download from our web site.
This contains full details on setup, wiring and installation.
