※ 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 EQ5: -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 EQ5: 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.
