5.1.3 Trip conditions monitoring
: Resetting/Initialization at power-on or with the reset terminal
turned on
: Stopping the motor
: Decelerating or operating the motor
: During constant speed
: Accelerating the motor
: Status after receiving a zero-frequency operation command
: Starting the motor
: Applying DC braking to the motor
: Overload-restricted operation
: Forcible or servo-on operation
These digits indicate a trip factor.
See Section 5.1.1.
This digit indicates the inverter status at tripping.
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
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.
