Setting
Configuration for the motorized potentiometer
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
The inverter limits the motorized potentiometer output to p1037.
Factory setting: 0 rpm
After quick commissioning, the inverter sets the parameter to the appro‐
priate value.
The inverter limits the motorized potentiometer output to p1038.
Factory setting: 0 rpm
After quick commissioning, the inverter sets the parameter to the appro‐
priate value.
Signal source for accepting the setting value. The motorized potentiometer
accepts the setting value p1044 on signal change p1043 = 0 → 1.
Factory setting: 0
Signal source for the setting value
