Load
becoming 0
Err30
1. The running current for frequency
converter is lower than F9-64
1.
Confirm whether the load is
disconnected or the parameter setting
of F9-64 and F9-65 meets the real
running conditions
PID
feedback lost
during
running
Err31
1. The PID feedback is lower than
the set value of FA-26
1. Inspect PID feedback signal or set
FA-26 as an appropriate value
Waveband
current limit
failure
Err40
1. Whether the load is too heavy or
motor stalling happens
2. Too small model selection for
frequency converter
1. Reduce the load and inspect the
motor and machinery conditions
2. Select the frequency converter with
higher power level
Motor
switchover
fault during
running
Err41
1. Change the current motor
selection through terminal when the
frequency converter is running
1. Conduct the operation of motor
switching
after
the
frequency
converter stops
Too large
speed
deviation
Err42
1. Incorrect parameter setting for
encoder
2. Parameter identification is not
conducted
3. Too large speed deviation, and
the detecting parameter F9-69 and
F9-70 are not reasonably set
1. Correctly set the encoder parameter
2. Conduct the motor parameter
identification
3. Reasonably set the detecting
parameter based on the actual
conditions
Motor

Err43
1. Incorrect parameter setting for
encoder
2. Parameter identification is not
conducted
1. Correctly set the encoder parameter
2.
