Parameter list
7.2 Parameter list
Parameter Function
Displays the motorized potentiometer setpoint before it passed the PID-MOP RFG.
P2247[0...2] PID-MOP ramp-up time of
the RFG [s]
Sets the ramp-up time for the internal PID-MOP ramp-function generator. The setpoint is changed from
zero up to limit defined in P1082 within this time.
Notice: Refer to: P2248, P1082
P2248[0...2] PID-MOP ramp-down
time of the RFG [s]
Sets the ramp-down time for the internal PID-MOP ramp-function generator. The setpoint is changed from
limit defined in P1082 down to zero within this time.
Notice: Refer to: P2247, P1082
r2250 CO: Output setpoint of
PID-MOP [%]
Displays output setpoint of motor potentiometer.
P2251 PID mode
Enables function of PID controller.
0
1
Dependency: Active when PID loop is enabled (see P2200).
P2253[0...2] CI: PID setpoint
Defines setpoint source for PID setpoint input. This parameter allows the user to select the source of the
PID setpoint. Normally, a digital setpoint is selected either using a fixed PID setpoint or an active setpoint.
P2254[0...2] CI: PID trim source
Selects trim source for PID setpoint. This signal is multiplied by the trim gain and added to the PID set-
point.
Setting: 755
2224
2250
P2255 PID setpoint gain factor
Gain factor for PID setpoint. The PID setpoint input is multiplied by this gain factor to produce a suitable
ratio between setpoint and trim.
P2256 PID trim gain factor
Gain factor for PID trim. This gain factor scales the trim signal, which is added to the main PID setpoint.
P2257 Ramp-up time for PID
setpoint [s]
Sets the ramp-up time for the PID setpoint.
Dependency: P2200 = 1 (PID control is enabled) disable normal ramp-up time (P1120). PID ramp time effective only on
PID setpoint and only active when PID setpoint is changed or when RUN command is given (when PID
setpoint uses this ramp to reach its value from 0 %).
