340 PID error value inversion
(2.9.9)
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
378 AI1 signal filter time
(2.2.8)
When this parameter is given a value greater than
0 the function that filters out disturbances from the
incoming analogue signal is activated.
Long filtering time makes the regulation response
slower. See Figure 10.

379 AI1 signal range
(2.2.3)
0 Signal range 0...20 mA
1 Signal range 4...20 mA
2 Signal range 0...10 V
3 Signal range 2...10 V
380 AI1 custom setting minimum
(2.2.5)
381 AI1 custom setting maximum
(2.2.6)
These parameters set the analogue input signal for any input signal span between
0.00...100.00%. However, the max value of par. ID380 cannot be greater than the value set for
parameter ID381, and the min value of par. ID381 cannot be smaller than the max value of par.
ID380.
Note: Parameter ID379

is inactivated if ID380 0% or ID381 100%. See also
