Parameterization with STARTER
In the STARTER commissioning tool, the "Fixed setpoints" parameter screen in the project
navigator under the relevant drive is activated by double-clicking Setpoint channel -> Fixed
setpoints.
2.5 Motorized potentiometer
Description
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, lower setpoint
● Invert setpoint (p1039)
● Configurable ramp function generator, e.g.:
– Ramp-up/ramp-down time (p1047/p1048) referred to p1082
– Setting value (p1043/p1044)
– Initial rounding-off active/not active (p1030.2)
● Non-volatile storage via p1030.3
● 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.:
– Switch on/off (p1030.1)
– Ramp-up/ramp-down time (p1047/p1048)
