SINAMICS G120 Control Units CU240B/E-2 Parameter Manual (LH11), 01/2011
Description: Sets the configuration for the motorized potentiometer of the technology controller.
Dependency: Refer to: r2231, p2240
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 p2240.
1: The setpoint for the motorized potentiometer is saved and after ON is entered using r2231. In order to save in a
non-volatile fashion, bit 03 should be set to 1.
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 specify-
ing small changes (progressive reaction when keys are pressed). The jerk for initial rounding is independent of the
ramp-up time and only depends on the selected maximum value (p2237).
It is calculated as follows:
r = 0.0001 x max(p2237, |p2238| ) [%] / 0.13^2 [s^2]
The jerk is effective until the maximum acceleration is reached (a_max = p2237 [%] / p2247 [s] or a_max = p2238
[%] / p2248 [s]), after which the drive continues to run linearly with constant acceleration. The higher the maximum
acceleration (the lower that p2247 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 p2230.0 = 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 r2250.
Description: Displays the setpoint memory for the motorized potentiometer of the technology controller.
For p2230.0 = 1, the last setpoint that was saved is entered after ON.
Dependency: Refer to: p2230
