Possible issues:
The power indicator light is not on
Subdivision too small
Is the current setting too low
Drive protected
Enable terminal level to be high
Unable to respond to control signals


Solution:
Check the power supply circuit and confirm that the polarity of the positive and negative poles of the power supply is correctly connected, and the power cord is reliably connected
Select the right subdivision
Select the right current
Power on again, unable to solve, refer to the description of the alarm indicator light on item
Control the level of the driver side enable port to be low or suspended
Increase the amplitude of the control signal to ensure that the high and low level time of the control signal comply with the description in the manual

Possible issues:
Wrong motor wire connection

Solution:
Swap two wires of the same phase for any two phases of the motor (such as A+, A - exchange wiring positions), and swap any two phases in the three-phase UVW

Possible issues:
Motor line short circuit
Wrong motor wire connection
Voltage too high or too low
Motor or driver damage

Solution:
Check and connect
Check wiring
Check the power supply
Replace the motor or driver

Possible issues:
Signal interference
Shielding ground not connected or not properly connected
There is an open circuit in the motor line
Subdivision error
Low current
Pulse direction timing incorrect
Loose connection between motor and load

Solution:
Eliminate interference
Reliable grounding
Check and connect
Set pair segmentation
Increase current
Change the effective edge of the pulse
Consider whether the connection and fixation method is reasonable

Possible issues:
Acceleration time too short
Motor torque too low
Low voltage or low current
The motor shaft is not concentric with the load

Solution:
Extended acceleration time
Select high torque motor
Increase voltage or current appropriately
Change the relative position of the motor shaft and load to make it concentric

Possible issues:
Asymmetric winding
Driver or motor malfunction
Speed at resonance point
Converted to a load inertia to rotor inertia ratio of more than 5 on the motor shaft

Solution:
Check motor wiring
Replace the driver or motor
Avoid using resonance points
Choose a large inertia motor or a reasonable reduction ratio to control the inertia ratio as small as possible

Possible issues:
The driver and motor are not reliably grounded for protection

Solution:
Reliable grounding of drivers and motors
