OVC Alarm

What does OVC mean?

This alarm is issued when a specific condition related to the OVC bit is detected. It is generally associated with a temperature rise in the motor or amplifier, indicating a potential for overheating under current operating conditions or parameter settings.

• Overcurrent alarm triggered by the system.
• Motor draw exceeding permitted current limits (P04-15).
• Mechanical overload or jam.
• Incorrect motor parameter configuration.

1. 1

   Verify that standard values are set for parameters No. 1877, No. 1878, No. 1893, No. 2062, No. 2063, and No. 2065.

2. 2

   If parameter settings are confirmed correct, increase the acceleration/deceleration time constant.

3. 3

   Increase the programmed stop time period to help suppress temperature rise.
