04 Ramp-function generator always active Yes No -
Dependency: See also: r2231, p2240
Note
For 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.
For 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 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.
For bit 03:
0: Non-volatile data save deactivated.
1. The setpoint for the motorized potentiometer is saved in a non-volatile fashion (for p2230.0 = 1).
For 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.
r2231 Technology controller motorized potentiometer setpoint memory / Tec_ctrl mop mem
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: - Dynamic index: -
Unit group: 9_1 Unit selection: p0595 Function diagram: 7954
Min:
- [%]
Max:
- [%]
Factory setting:
- [%]
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.

p2235[0...n] BI: Technology controller motorized potentiometer raise setpoint / Tec_ctrl mop raise
Access level: 3 Calculated: - Data type: Unsigned32 / Binary
Can be changed: T Scaling: - Dynamic index: CDS, p0170
Unit group: - Unit selection: - Function diagram: 7954
Min:
-
Max:
-
Factory setting:
0
Description: Sets the signal source to continually increase the setpoint for the motorized potentiometer of the technology controller.
The setpoint change (CO: r2250) depends on the set ramp-up time (p2247) and the duration of the signal that is
present (BI: p2235).
