3. Function Explanation
■
F18 Bias frequency
This function adds a bias frequency to the set frequency value
to analog input.
The operation follows the figure below.
When the bias frequency is higher than the maximum fre-
quency or lower than the – (minus) maximum frequency, it is
limited to the maximum or –maximum frequency.
■
F20 DC brake (Starting freq.)
■
F21 DC brake (Braking level)
■
F22 DC brake (Braking time)
Starting frequency: This function sets the frequency at which
DC injection brake starts operation during deceleration, to
decelerate the motor to a stop.
- Set values:0.0 to 60.0Hz
Operation level: This function sets the output current level
when a DC injection brake is activated. Set a percentage of
inverter rated output current in 1% steps.
- Set values: G11S: 0 to 100%
P11S: 0 to 80%
Time: This function sets the time of a DC injection brake
operation.
- Set value 0.0: Inactive
0.1 to 30.0s
■
F15 Frequency limiter (High)
■
F16 Frequency limiter (Low)
This function sets the upper and lower limits for the setting
frequency .
- Set values: G11S: 0 to 400Hz
P11S: 0 to 120Hz
* The inverter output starts with the starting 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 (for frequency setting signal)
This function sets the rate of the set frequency value to analog
input.
Operation follows the figure below.
