Page 6: Connecting To Power
920-0128 Rev C STRAC8 Hardware Manual 03/26/2021 3.1 Connecting to Power Use the supplied connector to connect to the AC supply according to the diagram below. Use 16 AWG wire for Line (L) and Neutral (N). Use 14 AWG for Earth Ground (G). Care should always be taken when working with high voltages. -
Page 7: Connecting To A Motor
920-0128 Rev C STRAC8 Hardware Manual 03/26/21 3.2 Connecting to a Motor Motor connections should be made according to the following diagrams. Never connect or disconnect the motor while the power is on. Note: it is highly recommended that you use a motor with a shielded cable with the STRAC8. Always connect the cable drain wire to the drive’s terminal (next to the A+ terminal) The recommended Applied Motion motors for the STRAC8 include shielded cables. - Page 8 920-0128 Rev C STRAC8 Hardware Manual 03/26/2021 Six lead motors can be connected in series or center tap. In series mode, motors produce more torque at low speeds, but cannot run as fast as in the center tap configuration. In series operation, the motor should be operated at 30% less than the rated current to prevent overheating.

920-0128 Rev C STRAC8 Hardware Manual 03/26/21 3.3 Connecting the Inputs and Outputs 3.3.1 Step & Direction Inputs The STRAC8 Step Drive has two high speed optically isolated inputs called STEP and DIR. They accept 5 to 24 volt single-ended or differential signals, up to 2MHz. -
Page 10: Input
920-0128 Rev C STRAC8 Hardware Manual 03/26/2021 3.3.2 EN input The EN input enables or disables the drive amplifier. It is an optically isolated input that accepts a 5 to 24 volt single-ended or differential signal. The maximum voltage that can be applied to the input is 28V. When EN input is closed, the driver amplifier is deactivated, all the MOSFETs will shut down, and the motor will be free. -
Page 11: Fault Output
920-0128 Rev C STRAC8 Hardware Manual 03/26/21 3.3.3 Fault Output The FAULT Output is optically isolated. The maximum collector current is 100mA, and the maximum collector to emitter voltage is 30 volts. The output can be wired to sink or source current. When drive is working normally, the output is open. -

920-0128 Rev C STRAC8 Hardware Manual 03/26/21 4.2 Running Current The output current is set by the SW5, SW6, SW7and SW8 switches. There are 16 settings. NOTE: Drive’s running current will be limited by the lower value between motor selection rotary switch and the dip current switch Current (Peak) 0.4A... -
Page 14: Anti Resonance
920-0128 Rev C STRAC8 Hardware Manual 03/26/2021 4.4 Anti Resonance The SW11 and SW12 switches select the load inertia. There are 4 settings. The inertia selection can help the STRAC8 drive to calculate the current control parameter. If the load inertia is close to that of the motor rotor, the low setting should be selected. If the load inertia is higher than that of the rotor, a proportionally higher setting should be selected. -
Page 15: Motor Selection
920-0128 Rev C STRAC8 Hardware Manual 03/26/21 5 Motor selection Each position of the 16-bit rotary switch selects a different motor, and automatically sets 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. -
