Nema 8 11 14 16 17 Digital Stepper Driver Manual:

1, Q: The motor does not turn and no holding torque:

     A: ① check whether the power line is connected to the wrong voltage is too low, need to increase the voltage or correct the power line

         ② check whether the motor wiring is correct, if not correct motor wiring. Check if the motor wiring is correct, if not, correct the motor wiring.

         ③ Whether the enable signal is valid, resulting in the motor does not work.

         ④ Is the subdividing parameter correct?

         ⑤ Is the current parameter correct?

2、Q：Motor does not rotate but has holding torque:

      A: ① The phase sequence of motor wires is wrong, need to swap any two wires.

          ② Pulse signal input is wrong, need to check the pulse wiring.

3、Q: The motor torque is too small:

      A: ① Phase current setting is too small, need to set the phase current corresponding to the motor.

          ② acceleration is too fast, reduce the acceleration value

          ③ motor blocking, need to rule out mechanical problems

          ④ drive and motor mismatch, need to replace the appropriate drive

4、Q：Motor steering error:

      A: ① motor line phase sequence is wrong, need to swap any two wires

          ② motor line has a broken circuit, check and connect the right

5、Q：The alarm indicator light is on:

     A: ① Is the motor wire connected incorrectly

         ② Whether there is over-voltage and under-voltage conditions

         ③ Motor or driver is damaged

6、Q：Motor acceleration blocking:

     A: ① short acceleration time

         ② motor torque is too small

         ③ Low voltage or current
