Velocity Limit Value Exceeded

‘S-0-0040, Velocity feedback value’ has exceeded the1.125-fold value of one of the parameterized velocity limit values
Velocity control loop unstable or too heavily oscillating due to incorrect parameterization
All firmware products not requiring export licenses released as of 2014-12-311) (functional packages ‘0: open-loop package’ or ‘1: closed-loop package’): The actual velocity values reached in open-loop operation correspond to an inverter output frequency ≥ 600 Hz. As regards firmware products not requiring export licenses, the velocity limit value is active in open-loop operation and closed-loop operation in the following versions and above: MPx02V38, MPx03V38, MPx04V50, MPx05V34, MPx07V38, MPx08V16

Check and, if necessary, correct parameterization of ‘S-0-0091, Bipolar velocity limit value’, ‘S-0-0038, Positive velocity limit value’ and ‘S-0-0039, Negative velocity limit value’. MPx06 and above: Within parameterized standstill window (S-0-0124), actual velocity is not monitored for resulting limits from S-0-0091, S-0-0038 and S-0-0039.
Check and, if necessary, correct parameterization of velocity controller
Check operability: Does the drive follow a preset velocity command value? If necessary, ensure operability by repeating commissioning. Open-loop operation:Check slip compensation. In the case of overcompensation, velocity feedback value can be higher than velocity command value. If necessary, reduce velocity command value or rated slip frequency (P-0-0600). Open-loop operation and closed-loop operation: Check whether inverter output frequency (P-0-0580) is ≥ 600 Hz. Check whether another connected motor ‘tows’ the motor to a higher velocity.
