AC70 VC CONTROL FREQUENCY INVERTER MANUAL
E-33
Free stop frequency
FUNCTION PARAMETER DETAILED SPECIFICATION
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
stop freely. Generally coordinate external mechanical braking to achieve quick stop when this stop mode has been
selecting.

DC braking voltage: The value of voltage which is injected to motor when executing DC braking function. The
value of voltage benchmark against the input rated current of inverter.
This function can output torque under zero speed. Generally, it uses to improve the stop accuracy and realize quick
stop, but it can’t be apply for normal deceleration. The inverter will stop output once DC braking has been
performed. If the DC raking current set to big, over current fault occurs easily during stop.
DC braking time when stop: DC braking current lasting time when inverter stops, if the braking time is set to 0, it
means the DC braking function is disabled.
DC braking starting frequency when stop It means when inverter decelerated to this frequency, the inverter
will stop output, and perform the DC braking function. If the output frequency less than DC braking starting
frequency when stop during running process, the inverter will stop output, start DC braking function when receiving
the stop command.
The inverter will start DC braking, and the output frequency jump to zero if the frequency given less than DC
braking staring frequency when stop during the deceleration process. The DC braking staring frequency when stop
should be set smaller when there are no strictly requirement for stop. When the DC braking staring frequency when
stop［E-37］parameters setting smaller than free stop frequency［E-33］setting, the inverter will decelerate to free
stop frequency, and then stop output execute DC braking.
DC braking time when start: It refer to DC braking voltage lasting time when stop, Only if ［E-30］parameters
unit digit set to 1, the DC braking function will be enabled. When the braking time set to 0.0s, not perform DC
braking function
