䊶Excessive noise applied on the inverter
䊶Reduce the noise around the inverter.
䊶Check the OPEN arrival signal and

En1 䊶There is no encoder pulse
䊶Check the encoder's power supply
䊶Check the encoder's wiring
Details and cause of fault Remedies
䊶The rotation direction of the encoder
pulse is different from the rotation
direction of a command
䊶Check the encoder's wiring
(phase A and phase B)
䊶Check the OPEN arrival signal.
䊶Check the CLOSE arrival signal

Resetting Fault Trips
If a fault is displayed on the operation panel's main display and the inverter is
stopped, remedy the fault before resetting. It is possible to restart the inverter
after resetting.
Power
reset
䃂 Turn OFF the power once, then turn it ON again.
(Operation can be started when the power is turned ON again.)
Resetting
by stop
signal
㽲 When operation is set to local (Parameter P08 set to "0" or "1"), the fault
will be reset when the "STOP button" on the operation panel is pressed.
㽳 When operation is set to external ( Parameter P08 set to "2"), the fault
will be reset when both the OPEN/CLOSE signal are turned OFF.
㽴 When operation is set to communication ( Parameter P08 set to "3"),
the fault will not be reset even if the operation command of communication
is turned OFF. In case of communication setting, the fault will be reset with
"fault reset command".
Resetting
by panel
䃂 The fault will be reset when the "STOP button" on the operation panel
is pressed.
Depending on the start mode function setting, if the fault trip is reset
with inputting the run signal, the inverter may restart suddenly.
(Reset the trip after ensuring personal safety.)
Failure to do so could lead to injury.
