Table 7- 5 Extended setup of motorized potentiometer
Parameter Description
P1030 Configuration of the MOP, parameter value with four independently adjustable bits
00 … 03 (factory setting 0110 bin)
Bit 00: Save setpoint after switching off motor
0: After the motor is switched on, p1040 is specified as the setpoint
1: Setpoint is saved after the motor is switched off and set to the saved value once it
is switched on
Bit 01: Configure ramp-function generator in automatic mode (1-signal via BI: p1041)
0: No ramp-function generator in automatic mode (ramp-up/-down time = 0)
1: With ramp-function generator in automatic mode
In manual mode (0-signal via BI: p1041) the ramp-function generator is always active
Bit 02: Configure initial rounding
0: No initial rounding
1: With initial rounding. The initial rounding is a sensitive way of specifying small
setpoint changes (progressive reaction when keys are pressed).
Bit 03: Store setpoint in power-independent manner
0: No power-independent saving
1: Setpoint is saved in the event of a power failure (bit 00 = 1)
P1035 Signal source to increase setpoint (factory setting 0)
Automatically pre-assigned during commissioning, e.g. with the button on the
Operator Panel
P1036 Signal source to reduce setpoint (factory setting 0)
Automatically pre-assigned during commissioning, e.g. with the button on the
operator panel
P1037 Maximum setpoint (factory setting 0 rpm)
Automatically pre-assigned during commissioning
P1038 Minimum setpoint (factory setting 0 rpm)
Automatically pre-assigned during commissioning
P1039 Signal source to invert minimum and maximum setpoints (factory setting 0)
P1041 Signal source to switch from manual to automatic (factory setting 0)
P1042 Signal source for setpoint in automatic mode (factory setting 0)
P1043 Signal source to accept set value (factory setting 0)
E.g. command to switch on motor
P1044 Signal source for set value (factory setting 0)
