※ The inverter output starts with the start frequency when
operation begins, and stops with the stop frequency
when operation ends.
※ If the upper limit value is less than the lower limit value,
the upper limit value overrides the lower limit value.
※ When lower limit value is set, the inverter operates with
lower limit value at operation command is "ON" even
frequency command is zero(0Hz).
This function sets the rate of the set frequency value
to analog input.
Operation follows the figure below.

This function adds a bias frequency to the set
frequency value to analog input.
Setting range G11S: -400.0 to +400.0Hz
P11S: -120.0 to +120.0Hz
The operation follows the figure below.
When the bias frequency is higher than the maximum
frequency or lower than the - maximum frequency, it is
limited to the maximum or - maximum frequency.

※ Reversible operation is valid if the function code
F01/C30 is set to "4" or "5" only.
※ This function is invalid if PID control is selected(H20 is
"1" or "2").
Starting frequency: This function sets the frequency
with which to start a DC injection brake to decelerate
the motor to a stop.
Setting range: 0 to 60Hz
Operation level: This function sets the output current
level when a DC injection brake is applied. Set a
percentage of inverter rated output current in 1% steps.
Setting range G11S: 0 to 100%
P11S: 0 to 80%
Time: This function sets the time of a DC injection
brake operation.
Setting range 0.0: Inactive
0.1 to 30.0 seconds
CAUTION
Do not use the inverter brake function for
mechanical holding.
Injury may result.
