Applied Motion Products STRAC2 Stepper Drives
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 single-phase.
- A source of pulse & direction signals
INSTALLATION STEPS
Step 1 -Wiring AC Power Supply
DO NOT apply power until all connections to the drive have been made
- Select Power input voltage AC input voltage must be selected by switch. Check input voltage to avoid damage before powering ON
- 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 according to the
diagram to the right.
Use 16 AWG wire for Line (L) and Neutral (N). Use 14 AWG for Earth Ground (G)
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 STRAC2 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.
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 motor current , anti-resonance and other settings
Step 4 – Config the Drive
Many operational parameters of the STRAC2 can be set or changed by DIP switches – either by a single switch or a combination of ON/OFF settings of 2 or more switches
- Microstepping – 4 switches for a total of 16 setting

Option SW10 Inertia 0 ON Low 1 OFF High - Step Smoothing Filter (SW11) – ON to enable, OFF to disable
Step 5 – Self Test
The STRAC2 has a built in Self Test function. If switch 12 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.
