Extended setpoint channel

3.2 Motorized potentiometer

3.2 Motorized potentiometer
This function is used to simulate an electromechanical potentiometer for setpoint input.
You can switch between manual and automatic mode for setpoint input. The specified
setpoint is routed to an internal ramp-function generator. Setting values, start values and
braking with OFF1 do not require the ramp-function generator of the motorized
potentiometer.
The output of the ramp-function generator for the motorized potentiometer is available for
further interconnection via a connector output (e.g. interconnection to connector input p1070
- CI: Main setpoint, an additional ramp-function generator is then active).
Properties for manual mode (p1041 = 0)
● Separate binector inputs for Raise and Lower are used to adjust the input setpoint:
– p1035 BI: Motorized potentiometer, setpoint, raise
– p1036 BI: Motorized potentiometer, setpoint, lower
● Invert setpoint (p1039)
● Configurable ramp-function generator, e.g.:
– Ramp-up/ramp-down time (p1047/p1048) referred to p1082
– Setting value (p1043/p1044)
– Activate/deactivate initial rounding (p1030.2 = 1/0)
● Non-volatile storage of the setpoints via p1030.3 = 1
● Configurable setpoint for Power ON (p1030.0)
– Starting value is the value in p1040 (p1030.0 = 0)
– Starting value is the stored value (p1030.0 = 1)
Properties for automatic mode (p1041 = 1)
● The input setpoint is specified via a connector input (p1042).
● The motorized potentiometer acts like a "normal" ramp-function generator.
● Configurable ramp-function generator, e.g.:
– Activate/deactivate (p1030.1 = 1/0)
– Ramp-up/ramp-down time (p1047/p1048)
– Setting value (p1043/p1044)
– Activate/deactivate initial rounding (p1030.2 = 1/0)
● Non-volatile storage of the setpoints via p1030.3 = 1
● Configurable setpoint for Power ON (p1030.0)
– Starting value is the value in p1040 (p1030.0 = 0)
– Starting value is the stored value (p1030.0 = 1)
