Table 7- 5 Extended setup of motorized potentiometer
Parameter
Description
p1030
MOP configuration (factory setting: 00110 bin)
.00 Storage active
= 0: After the motor has been switched on, the setpoint = p1040
= 1: After the motor has switched off, the inverter saves the setpoint. After the
motor has switched on, the setpoint = the stored value
.01 Automatic mode, ramp-function generator active (1-signal via BI: p1041)
= 0: Ramp-up/ramp-down time = 0
= 1: With ramp-function generator
In manual mode (p1041 = 0), the ramp-function generator is always active.
.02 Initial rounding active
1: With initial rounding. Using the initial rounding function it is possible to enter
very small setpoint changes
.03 Storage in NVRAM active
1: If bit 00 = 1, the setpoint is retained during a power failure
.04 Ramp-function generator always active
1: The inverter also calculates the ramp-function generator when the motor is
switched off
p1037
MOP maximum speed
(factory setting: 0 rpm)
Automatically pre-assigned when commissioning
p1038
MOP minimum speed
(factory setting: 0 rpm)
Automatically pre-assigned when commissioning
p1039
Motorized potentiometer, inversion
(factory setting: 0)
Signal source for inverting the minimum speed / velocity or maximum speed / velocity
p1041
Motorized potentiometer, manual/automatic
(factory setting: 0)
Signal source for switchover from manual to automatic
p1043
Motorized potentiometer, accept setting value
(factory setting: 0)
Signal source for accepting the setting value. The motorized potentiometer accepts
the setting value p1044 on signal change p1043 = 0 → 1.
p1044
MOP setting value
(factory setting: 0)
Signal source for the setting value.
