5.1.3 Trip conditions monitoring

2) Output frequency (Hz) at tripping
3) Output current (A) at tripping
4) DC voltage (V) across P and N terminals at tripping
5) Accumulated time (h) for which the inverter has
been running before tripping
6) Accumulated time for which the inverter power has
been on before tripping
1) Trip factor
These digits indicate a trip factor.
See Section 5.1.1.
Note: The above descriptions indicate the inverter status at the occurrence of
tripping, which may not correspond to the apparent operation of the motor.
(Example)
When the PID control is used or the frequency command is input as an analog
signal (a voltage or current signal), the inverter may repeat acceleration and
deceleration alternately at short intervals to make up for the fluctuations of the
analog signal, even if the motor is apparently running at constant speed.
In such cases, the inverter status at tripping may not correspond to the
apparent operation of the motor.
5-9
This digit indicates the inverter status at tripping.
