Function Parameters
AC10 Inverter
initial frequency for DC braking (F601), DC braking will stop the motor immediately
During the process of braking during stopping, if “start” signal is given, DC braking will be
finished and inverter will start.
If “stop” signal is given during the process of braking during stopping, inverter will have no
response and DC braking during stopping still goes on.
Parameters related to “DC Braking”: F601, F602, F603, F604, F605 and F606, interpreted as
follows:
a) F601: Initial frequency of DC-braking. DC braking will start to work as inverter’s output
frequency is lower than this value.
b) F604: Braking duration before starting. The length of time for DC braking before inverter
starts
c) F605: Braking duration when stopping. The length of time for DC braking while inverter
stops.
Note: during DC braking, because motor does not have self-cooling effect caused by rotating, it
is in a condition of easy over-heating. Do not set DC braking voltage too high or set DC
braking time to long.
DC braking, as shown in Figure 9-11.

F607 is used to set selection of stalling adjusting function.
Voltage control: when motor stops quickly or load changes suddenly, DC bus voltage will be
high. Voltage control function can adjust deceleration time and output frequency to avoid OE.
When braking resistor or braking unit is used, do not use voltage control function
otherwise, the deceleration time will be changed.
Current control: when motor accelerates quickly or load changed suddenly, inverter may trip
into OC. Current control function can adjust accel/decel time or decrease output frequency to
control proper current value. It is only valid in VF control mode.
Note: (1) Voltage/current control is not suitable for lifting application.
(2) This function will change accel/decel time. Please use this function properly.
Initial value of stalling current adjusting is set by F608, when the present current is higher than
rated current *F608, stalling current adjusting function is valid.
During the process of deceleration, stalling current function is invalid.
During the process of acceleration, if output current is higher than initial value of stalling current
adjusting and F607=1, then stalling adjusting function is valid. Inverter will not accelerate until
the output current is lower than initial value of stalling current adjusting.
In case of stalling during stable speed running, the frequency will drop. If the current returns to
