E-31
Power off restart selection
Range:0,1
Default:0
E-32
Power off restart waiting time Range:0.0-10.0s Default:0.5s
Power off restart selection:
0: Disable
Inverter runs must receive running command given after power off when Power on.
In operator keypad or RS485 communication control mode, the running command will be clear automatically when
inverter off.
In the external terminal control mode, the control command of FWD/REV terminal is valid, ignore any parameters
setting of
[E-31]
when power on again after inverter power off.
1: Enable
If inverter is running before power off, the inverter starts automatically after waiting time
[E-32]
setting
when power on again.
Note: The restart power off function enable inverter operates automatically after power on again. There fore,
there is huge contingency, please be cautious to apply this function ensure safety of person and
equipment.
Power off restart waiting time:
when the
[E-31]
setting is valid, inverter starts operation after waiting time
[E-32]
when power on again.
The principles of this time setting is base on the factors such as the work resume preparation time of equipments
which correlate with the frequency inverter after power on again.

frequency
Range:0.00-60.00Hz Default:0.00Hz
When inverter receives the stop command under deceleration stop mode, it will decelerate to free stop frequency
base on the deceleration time, and then lock output, motor stop freely.
Note: This function is valid in stop mode only, disable in Forward/Reverse process.
E-34
Stop mode
Range :0,1
Default:0
0: Deceleration stop
Inverter stop output after decelerate to free stop frequency according to deceleration time
and deceleration mode given.
During the decelerate process, when the frequency given less than starting frequency of DC braking stop, the
output frequency will jump to zero, and perform DC injection braking, after then stop working if the DC injection
braking function is activated.
During the deceleration process, when the DC bus voltage over the
[E-53]
dynamic braking threshold voltage value,
the inverter will output pulse voltage base on dynamic braking ratio
[E-54]
setting for built in braking unit model
( through 15G/18.5P), able to connecting external braking resistor. For no built braking unit machine, can connect
external braking unit.
This stop mode mainly used to application which need quick braking required.
1: Free stop
After receiving the stop command, frequency inverter will block the output and motor will run to
