Function
This parameter sets the max. time for the drive operation when the PID
regulator output continuously operates at its min. value (
P237
).
If this is true for a time equal to the time set in
P255
, the drive is automatically
put on stand-by until
1) the PID output value exceeds the min. value (if
P237a
=Disabled);
2) the Feedback or the Error drops below the Wake-up level in
P237b
(if
P237a
=1 or =3 respectively);
3) when the Feedback or the Error exceeds the Wake-up level in
P237b
(if
P237a
=2 or =4 respectively).
If
C294
is set as External Out or
P255
is set to zero, this function is disabled.

Function
This parameter limits the max. acceleration for the PID regulator output.
The max. acceleration for the PID regulator output is equal to 100% /
P256
[%/msec].

Function
Gain for the scaling of PID measures
M023
÷
M025
.
This gain has effect only on the measures above. It does not affect the PID
operation.
This parameter allows scaling if you want to display PID measures with a
different unit of measure:

Function
Value of the Anti Wind-Up coefficient that freezes the integral term of the PID
when its output is being saturated (see Anti-windup).
When leaving
P260
=1.00, Anti Wind-Up is complete (I
OUTsat – P – D).
If
P260
=0.00, Anti Wind-Up is inhibited (the integral term reaches the value of
±
P238
based on the error sign).
Intermediate values for
P260
give intermediate effects.
