Panasonic Servo Drive Error Codes

When in Trouble, Protective Function (What is Error Code ?)

Various protective functions are equipped in the driver. When these are triggered, the

motor will stall due to error, the driver will turn the Servo-Alarm output (ALM) to off (open).

Use the external regenerative resistor.
2) Regenerative energy has not been absorbed in the specified time due to a high motor rotational speed. 2) Check the running pattern (speed monitor).

Note) If the internal positional command speed is forcibly set to 0 due to instantaneous stop caused by the command pulse inhibit input (INH) or CW/CCW over-travel inhibit input, the speed deviation rapidly increases at this moment. Pr6.02 setup value should have sufficient margin because the speed deviation also largely increases on the rising edge of the internal positional command speed. • Lengthen the acceleration/deceleration time of internal positional command speed, or improve the follow-up characteristic by adjusting the gain.
