Hi Pavlin,
Please disconnect the motor, power the board and check the following:
SLEEPn is a logic high and RESET is a logic low
All faults are cleared
ENBL bit is set to a 1
At this point the AOUT1 and BOUT1 outputs should be at VM and the AOUT2 and BOUT2 outputs should be at ground. This indicates the device is operational.
Once device operation is confirmed, the step input will cause the outputs to reverse per the indexer table.
The motor can now be reconnected. The motor may require an acceleration profile to achieve the desired speed.
