This alarm is tripped when the motor is over-currented.
▪ Check if the acceleration parameter (No. 29) and the deceleration
parameter (No. 30) are set to less than specified.
▪ Check the wiring of the motor power cable, and replace it if necessary.
This alarm occurs if the CPU or the MCB of the servo drive has an error.
▪ Reset the parameters of the servo drive, and set them as appropriate again.
▪ Then, turn off the servo drive and turn it back on. See if there occurs the
same alarm. If so, replace the drive because this alarm is tripped from the
defective drive (a MCB error).
