Siemens MICROMASTER 440 Operating Instructions Manual page 171

Issue 10/06
If the motorized potentiometer is to be used as setpoint source, then either
parameter P1000 or P0719 should be modified or the BICO parameter r1050
should be connected to the main setpoint P1070 or supplementary setpoint P1075.
Contrary to parameter P0719, when parameter P1000 is modified, this implicitly
changes BICO parameters P1070, P1075.
Example:
a) Standard method
b) BICO method
The MOP is configured using the following parameters and has the mode of
operation as shown in Table 3-24:
Limits using the minimum frequency P1080 or maximum frequency P1082
Ramp-up/ramp-down time P1120 or P1121
Inhibits MOP reversing function P1032
Saves the MOP setpoint P1031
MOP setpoint P1040
