代碼 F01614: Frequency consistency fault

Reaction: OFF 2 (OFF 3) Acknowledge: Quit fault eg. via DI2 Cause: Error in frequency detection of the frequency estimation circuit (voltage frequency measurement (VFM) module): - r0949 = 100: Difference in frequency comparison on P1. - r0949 = 101: VFM estimated frequency too high on P1. - r0949 = 102: VFM estimated frequency too low on P1. - r0949 = 103: Estimated frequency of VFM module was not detected on P1. - r0949 = 104: Error in cycle-time on P1. - r0949 = 200: Frequency deviation on P2. - r0949 = 201: VFM estimated frequency too high on P2. - r0949 = 202: VFM estimated frequency too low on P2. - r0949 = 203: Estimated VFM frequency was not detected on P2. - r0949 = 204: Error in cycle-time on P2. Error can occur with small ramping times. When the VC or SLVC mode is configured (see p1300) the cause can be the same as for fault F0453. Remedy: - Increase ramping times p1120 and p1121. - Make sure that drive is not at current limit when starting. - See remedies for F0453. - Check hardware speed estimation circuit.
