Code
PoFF System power off
Communication between keypad
and main control plate failed
Cause
 The output of the inverter is short
circuited with the ground.
 There is fault in the current
detection circuit.
 The actual motor power sharply
differs from the inverter power.
 The load is too heavy or stalled.
 The control parameters of the
synchronous motors not set
properly.
 The autotune parameter is not
right.
 The inverter is not connected to
the motor.
 The inverter will report the
underload pre-alarm according
to the set value.
 Encoder line sequence error, or
signal wire is connected
improperly
 Encoder speed signal is contrary
to the motor running direction
 Z signal wire is disconnected
 Motor overtemperature input
terminal is valid
 Temperature detection resistor is
abnormal
 Motor runs in overload condition
in long time or it is abnormal
State type
 Check if the connection of the motor
is normal or not
 Change the Hall
Change the main control panel
 Set motor parameters correctly.
 Check the load and ensure it is
normal. Increase the detection time.
 Check whether the control
parameters are normal.
 Check the load and ensure it is
normal.
 Check whether the control
parameter is set properly or not.
 Increase the maladjustment
detection time.
 Check the load and the underload
pre-alarm point.
 Check encoder wiring
 Reset encoder direction
 Check Z signal wiring
 Check the wiring of motor
overtemperature input terminal
(terminal function 57)
 Check temperature sensor functions
normally
 Check motor functions normally
Possible cause
System power off or bus
voltage is too low
Keypad is connected
improperly
