F15 Frequency limiter (High)
F16 Frequency limiter (Low)
F 1 5 H L I M I T E R
F 1 6 L L I M I T E R
Set values: 0 to 400 Hz
These functions are used to define the upper and lower
limits of the set frequency.
The drive 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.
F17 Gain
F 1 7 F R E Q G A I N
This function assigns the rate of the set frequency value
to analog input.
Operation follows the figure below.
F18 Bias frequency
F 1 8 F R E Q B I A S
This function adds a bias frequency to the set frequency
value from analog input.
The operation follows the figure below. If the bias
frequency is higher than the +Maximum frequency or
lower than the -Maximum frequency, it is limited to the
+Maximum or -Maximum frequency.
F20 DC injection Brake (starting)
F21 DC injection brake (operation level)
F22 DC injection brake (time)
F 2 0 D C B R K H z
Set values: 0 to 60 Hz
Starting frequency: This function sets the frequency with
which to start a DC injection brake in order to decelerate
the motor to a stop.
F 2 1 D C B R K L V L
Set values: 0 to 100%
Operation level: This function sets the output current
level, when a DC injection brake is applied, as a percent-
age of the rated output current in 1% increments.
F 2 2 D C B R K t
Set value 0.0: Inactive
0.1 to 30.0 seconds
Time: This function sets the time for a DC injection
brake operation.
CAUTION
Do not use the drive brake function for
mechanical holding. Injury may result.
