LM2060H Nema34 86 Stepper Motor Driver

Hybrid Stepper Motor Driver Description：

Electrical Specifications

Current Selection

Standstill Current Setting

SW4 is used for standstill current setting. OFF meaning that the standstill current is half of the  dynamic current; and ON meaning that standstill current is the same as the selected dynamic  current. Usually the SW4 is set to OFF, in order to reduce the heat of the motor and driver.

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
