Parameter Remark
p2291 CO: Technology maximum limiting (factory setting: 100 %)
p2292 CO: Technology minimum limiting (factory setting: 0 %)
Table 6-47 Manipulating the actual value of the technology controller
Parameter Remark
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.
p2270 Technology controller actual value function
0: No function
1: √
2: x

Autotuning of the PID controller
Autotuning is an inverter function for the automatic optimization of the PID controller.
For active autotuning, the inverter interrupts the connection between the PID controller and
the speed controller. Rather than the PID controller output, the autotuning function provides
the speed setpoint.
