Voltage Controller
Parameter 53
Initial state
voltage 000%
BPQ, XPQ
Voltage controller: initial state of the actuator 0 to 100 %
The value entered for this parameter is the start reference point for the analog out-
put to the voltage controller. If the output to the voltage control has been disabled,
the output will act as a control position reference point. The percentage value con-
figured here refers to the range of the analog signal configured by "Stepper sign.vol
(min.)" (Parameter 62) and "Stepper sign.vol (max.)" (Parameter 63).
Exam
ple: If a 0 to 10 V signal is configured with a min. limit of 10% and a max.
limit of 90%, the reference range is 1 to 9 V. A setting of 25% would result a start
reference point of 3 V. Refer to the Special Applications chapter of the Application
Manual 37240 for more detailed information about this setting.
Parameter 54
Volt.controller
ON
Voltage controller: activation ON/OFF
ON ................ Generator voltage control is performed by the GCP-30. The subse-
quent screens of this function are displayed.
OFF .............. Generator voltage control is not performed by the GCP-30. The sub-
sequent screens of this function are not displayed.
Parameter 55
Start voltage
V control. 000V
Voltage controller: start voltage 12.0 to 100.0 %
L This value refers to the generator voltage set point (Parameter 16).
The voltage controller is activated when the monitored generator voltage has ex-
ceeded the value configured in this parameter. This prevents the GCP-30 from at-
tempting to control the voltage while the engine is completing its start sequence.
Parameter 56
Delayed. Start
V contr. 000s
Voltage controller: delayed start 0 to 999 s
The voltage controller is enabled after the configured time for this parameter ex-
pires.
NOTE
The following parameters for the voltage controller influence the power factor is controlled.
Parameter 57
V/Q contr.type
----------------
BPQ, XPQ
Voltage controller: type THREESTEP / ANALOG
THREESTEP The signal to the voltage control to increase/decrease the vol-
tage/power factor is output via the relay manager to any two confi-
gurable relays. The following relay functions must be assigned to the
individual relays.
• function 116 = increase voltage (V+) / power factor (Q+)
• function 117 = decrease voltage (V-) / power factor (Q-)
Refer to the Controller Outputs section of manual 37364 for wiring
an external Resistive/Capacitive protection circuit.
ANALOG .... Voltage control is performed via the analog outputs (terminals
11/12/13). The control of voltage/reactive power is performed via ei-
ther a voltage or current signal. The amplitude and signal type (mA
or V) to be utilized is configured in "V/Q contr.output" (Para-
m
eter 61). If a voltage signal is use, a jumper must be installed be-
tween terminals 11/12 (refer to the wiring diagram in manual 37364).
