p1030[0...n] Motorized potentiometer configuration / Mop configuration
Access level: 3
Can be changed: U, T
Units group: -
Min
-
Description: Sets the configuration for the motorized potentiometer.
Bit field: Bit Signal name
00 Data save active
01 Automatic mode, ramp-function generator
active
02 Initial rounding-off active
03 Save in NVRAM active
04 Ramp-function generator always active
Notice: For p0014 = 1, the following applies:
After the value has been modified, no further parameter modifications can be made and the status is shown in
r3996. Modifications can be made again when r3996 = 0.
Note: Re bit 00:
0: The setpoint for the motorized potentiometer is not saved and after ON is entered using p1040.
1: The setpoint for the motorized potentiometer is saved after OFF and after ON set to the saved value. In order to
save in a non-volatile fashion, bit 03 should be set to 1.
Re bit 01:
0: Without ramp-function generator in the automatic mode (ramp-up/ramp-down time = 0).
1: With ramp-function generator in the automatic mode.
For manual operation (0 signal via BI: p1041), the ramp-function generator is always active.
Re bit 02:
0: Without initial rounding-off
1: With initial rounding-off. The selected ramp-up/down time is correspondingly exceeded. The initial rounding-off is
a sensitive way of specifying small changes (progressive reaction when keys are pressed).
The jerk for the initial rounding-off is independent of the ramp-up time and only depends on the selected maximum
speed (p1082). It is calculated as follows:
r = 0.01 % * p1082 [1/s] / 0.13^2 [s^2]
The jerk acts up until the maximum acceleration is reached (a_max = p1082 [1/s] / p1047 [s]), and then the drive
continues to run linearly with a constant rate of acceleration. The higher the maximum acceleration (the lower that
p1047 is), the longer the ramp-up time increases with respect to the set ramp-up time.
Re bit 03:
0: Non-volatile data save de-activated.
1: The setpoint for the motorized potentiometer is saved in a non-volatile fashion (for bit 00 = 1).
Re bit 04:
When the bit is set, the ramp-function generator is computed independent of the pulse enable. The actual output
value of the motorized potentiometer is always in r1050.

CU240B-2 Access level: 3
CU240E-2
Can be changed: T
CU240E-2 F
Units group: -
Min
-
Description: Sets the signal source to continually increase the setpoint for the motorized potentiometer.
The setpoint change (CO: r1050) depends on the set ramp-up time (p1047) and the duration of the signal that is
present (BI: p1035).
Dependency: Refer to: p1036
Notice: The parameter may be protected as a result of p0922 or p2079 and cannot be changed.
