340 PID error value inversion 57 (2.2.32, 2.2.1.5)
This parameter allows you to invert the error value of the PID controller (and thus the
operation of the PID controller).
0 No inversion
1 Inverted
341 PID reference rise time 57 (2.2.33, 2.2.1.6)
Defines the time during which the PID controller reference rises from 0% to 100%.
342 PID reference fall time 57 (2.2.34, 2.2.1.7)
Defines the time during which the PID controller reference falls from 100% to 0%.
343 I/O B reference selection 57 (2.2.5, 2.2.1.1)
Defines the selected frequency reference place when the drive is controlled from the I/O
terminal and reference place B is active (DIN6=closed).
0 AI1 reference (terminals 2 and 3, e.g. potentiometer)
1 AI2 reference (terminals 5 and 6, e.g. transducer)
2 AI3 reference
3 AI4 reference
4 Keypad reference (parameter R32)
5 Reference from Fieldbus (FBSpeedReference)
6 Motor potentiometer reference
7 PID controller reference
- select actual value (par. ID333 to ID339) and the PID control reference (par. ID332)
If value 6 is selected for this parameter in Application 5, the values of parameters ID319
and ID301 are automatically set to 13.
In Application 7, the functions Motorpotentiometer DOWN and Motorpotentiometer UP
must be connected to digital inputs (parameters ID417 and ID418), if value 6 is selected
for this parameter.
