Solution of Leadshine DMA860h Driver

phenomenon

Possible problem

solution



The motor does not rotate

Power light is off

Working normal  

Current setting is too small

According to the rated current of the motor, select the appropriate current gear

Drive is protected

After the fault is excluded, power on again

Enable signal is low

This signal is pulled high or not connected

Wrong connection of motor wire

Arbitrarily exchange two wires of the same phase of the motor (for example, A + A- exchange wiring position)


Wrong direction of motor rotation

Motor wire is broken

Check and connect

Wrong connection of motor wire

Check wiring

Alarm indicator light


Wrong connection of motor wire

Arbitrarily exchange two wires of the same phase of the motor (for example, A + A- exchange wiring position)

The voltage is too high or too low

Check the power supply voltage

Damaged motor or driver

Replace motor or driver



Inaccurate location


Signal is disturbed

Eliminate interference

Shielded ground wire is not connected or not connected

Reliable ground

Segmentation error

Set subdivision correctly

Current is too small

Increase the current appropriately

Control signal problems

Check whether the control signal meets the timing requirements


Stall when the motor accelerates speed

The acceleration time is too short

Increase the acceleration time appropriately

Motor torque is too small

Choose high torque motor

Low voltage or too low current

Properly increase the voltage or set a larger current
