F0072
Motor overload fault (60 s in 1.5xlnom)
• P0156, P0157, P0158 setting is too
low in relation to the motor operating
current.
• Overload on the motor shaft
F0074 Ground overcurrent fault.
Note: This failure may be disabled by setting
P0343 = 0
• Short-circuit to the ground in one or
more output phases.
•
Motor cable capacitance too high,
causing current peaks in the output.
F0076
This fault indicates the motor presents phase loss,
imbalanced phase current or is disconnected.
•
Motor wiring or connection error.
• Loss of moto connection with the drive
or broken wire.
F0078
Overtemperature fault measured on the motor
temperature sensor (Triple PTC) via analog input
Alx or digital input Dlx
•
Overload on the motor shaft.
•
Load cycle is too high (high number of
starts and stops per minute).
• High ambient temperature around the
motor.
•
Poor contact or short-circuit
(3k9<RPTC<0K1).
• Motor thermistor not installed.
•
Motor shaft in stuck.
