Fault condition exists
Check wiring and restart power
The drive is disabled
Drive restore factory setting, and keep
ENA+, ENA- input signals unconnected.
Wrong motor rotation direction
The Direction signal level is reverse
Toggling the SW5 DIP switch
The drive in fault
Red light flashes once in a 5-second
period
The motor coil may short circuit or exiting
the wrong wiring
Red light flashes twice in a 5-second
period
The power supply exceeds Max. operation
voltage
Red light flashes 7-times in a 5-second
period
If using Leadshine’s motor, refer to motor
wiring in datasheet;If using 3
rd
motor, need
to swap the wiring of motor phase A+ and
phase A-
Red light is always on after power on
The drive is burned
Erratic motor motion
Control signal is too weak
Ensure the current of control signal is
within 7-16mA
Control signal is interfered
Don’t tie the control signal cable with
power cable together
Wrong motor connection
Refer to user manual of drive and motor
datasheet
Something wrong with motor coil
Check the motor is normal
Motor stalls during acceleration
Current setting is too small
Choose another power supply with lager
power or increase the output current of
drive
Motor is undersized for the application Choose another motor with higher torque
Acceleration is set too high
Reduce the acceleration
Power supply voltage too low
Choose another power supply with large
voltage output
Excessive motor & drive heating
Inadequate heat sinking / cooling
Refer to chapter 2.4
Motor peak current setting is too high
Reduce the current value refer to motor
datasheet
