CS2RS Series Modbus RS485 Closed Loop Stepper Drive User Manual
4.4.2 Drive Alarm Codes and Troubleshooting
Error code and cause:
The green light is always on after the drive power on. When the error is occurred, the drive will stop working and red light will
be flashed indicates the current error code. Whatever error occurs, the user need to power off the drive and restart it after
removing the error. The user can read the corresponding error code through the PC software. The latest errors will be saved to
EEPROM which supports 10 historical errors in the list.
1. Restart the drive;
2. If it still exists, check whether the motor is
short-circuited or not connected to the motor;
1. Restart the drive;
2. If it still exists, check the voltage of power
supply;
Current sampling
circuit error
1. Restart the drive;
2. If it still exists, the hardware failure
1. Check whether the motor wire is broken
1. Connect the drive to Leadshine software to
reset parameters to the factory
2. If it still exists, the hardware failure
1. Restart the drive;
2. If it still exists, disable auto-tuning by
0x01AB (Pr5.13).
1. Check if the value of encoder resolution
0x0233 (Pr7.01) is correct;
2. Check if the encoder cable is broken;
3. Check if the limit switch is damaged;
4. Check if the acceleration time is too small, or
the starting speed is too large
1. Check if the encoder cable is damaged;
2. Whether no encoder extension cable is
used;
Repeated settings
of input function
1. Check input function settings
