Parameter

Value

Motor type

2-phase bipolar stepper motor (4-wire, or 6/8-wire connected bipolar)

Output current

0.5 / 0.95 / 1.2 / 2.0 A peak per phase by jumper, 0.2–2.0 A by trimmer (Section 7.1); 2.0 A maximum†

Output voltage

equal to the motor supply (J5)

Connector

4-pin 2.54 mm header; mate TE 1770602-4 or compatible, or motor pigtail cable 210-291-01

Protection

driver over-current shutdown (7.2 A typical), thermal shutdown (160 °C typical), open-load detection; clamp diodes on each output

Pin 1 is at the end nearer the back wall (Figure 3). Do not connect or disconnect a motor while motor power is on.
