Remark
Limiting the output of the technology controller
In the factory setting, the output of the technology controller is limited to ± maximum speed. You must
change this limit, depending on your particular application.
Example: The output of the technology controller supplies the speed setpoint for a pump. The pump
should only run in the positive direction.

Manipulating the actual value of the technology controller
p2267
Technology controller upper limit actual value (factory setting: 100 %)
p2268
Technology controller lower limit actual value (factory setting: -100 %)
p2269
Technology controller gain actual value (factory setting: 100 %)
p2271
Technology controller actual value inversion (sensor type)
0:
No inversion
1: Inversion actual value signal
If the actual value decreases with increasing motor speed, then p2271 must
be set = 1.
