Parameter: Balancing frequency f2
•
Default setting (_:141) Balancing frequency f2 = off
With the parameter Balancing frequency f2, you specify whether you wish to issue balancing
commands for the frequency f2 on the generator side or not.
Parameter Value Description
off
If you select this setting value, no balancing commands are issued for the
frequency f2 on the generator side.
balancing pulses
If you select this setting value, balancing commands are issued for the
frequency f2 on the generator side.
Parameter: T f pulse min
•
Default setting (_:142) T f pulse min = 0.10 s
With the parameter T f pulse min, you set the minimum time of the control pulse. It corresponds to the
minimum time to which the frequency controller responds. Set the time to this limiting value. The default
setting is a practicable value.
Parameter: T f pulse max
•
Default setting (_:143) T f pulse max = 1.00 s
With the parameter T f pulse max, you set the maximum time of the control pulse. The default setting is a
practicable value. This allows you to avoid overadjustment of the speed in case of major frequency differ-
ences.
Parameter: df/dt of the controller
•
Default setting (_:144) df/dt of the controller = 1.00 Hz/s
With the parameter df/dt of the controller, you adjust the balancing commands to the controller.
This allows the set point value to be specified correctly. The control pulse is derived from the measured differ-
ential frequency, the setting value of the parameter df/dt of the controller, and the set point value
Δf set point for balancing. The default setting is a practicable value.
Use the following equation to estimate the duration of the balancing pulse:
