Functions
8.10 Motorized potentiometer (MOP)
Control Units CU240S
Operating Instructions, 11/2006, A5E00766042B AA
8-49
The MOP functionality can be selected using the operator panel, digital inputs or the serial
interface. Parameterization is also possible directly using BICO parameters P1035 and
P1036 as well as parameter P0700. In this case, for a value assigned to P0700, the BICO
parameter is appropriately modified.
Example
Command source via "USS on RS232" (using the PC connection kit on the option port)
Standard method P0700 = 4
P1035 = 2032.13
P1036 = 2032.14
BICO method
…
(for a complete list refer to Parameter List P0700)
If the motorized potentiometer is to be used as a setpoint source, then parameter P1000
should be modified or the BICO parameter r1050 should be connected to the main setpoint
P1070 or supplementary setpoint P1075. When parameter P1000 is modified, this implicitly
changes BICO parameters P1070, P1075.
Example
Setpoint via the motorized potentiometer (MOP)
Standard method P1000 = 1
P1070 = 1050 BICO method
P1075 = 0
The MOP is configured using the following parameters and has the modes of operation as
shown in the table below.
● 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
