Setting range
[Default]
Description
measured generator
frequency must exceed 50.5
Hz (50 + 0.5) to issue a lower
pulse or fall below 49.5 Hz
(50 - 0.5) to issue a raise
pulse.
Synchronization
The generator frequency is
controlled in such a manner that
the measured frequency does not
deviate from the monitored
reference (mains or busbar)
frequency by more than the value
configured in this parameter
without the controller issuing a
frequency raise/lower signal to the
frequency control.
This prevents unneeded wear on
the frequency bias output control
or the raise/lower relay contacts.
The value configured for this
parameter must be less than the
value configured for the df max
(maximum frequency differential)
for synchronization.
Notes
This parameter is only visible if
frequency control (parameter
) is configured to "3pos
controller".

Time pulse minimum
1
0.01 to 2.00 s
[0.05 s]
A minimum pulse on time must be
configured here.
The shortest possible pulse time
should be configured to limit
overshoot of the desired speed
reference point.
Notes
This parameter is only visible if
frequency control (parameter
) is configured to "3pos
controller".

Gain factor
1
0.1 to 10.0
[5.0]
The gain factor K
p
influences the
operating time of the relays.
By increasing the number
configured in this parameter, the
operating time of the relay will be
in-creased in response to a
deviation from the frequency
reference.
By increasing the gain, the
response is increased to permit
larger corrections to the variable
to be controlled. The farther out of
tolerance the process is the larger
the response action is to return
the process to the tolerance band.
