P255 START Disable Delay with PID Out=P237
P255 Range
0 ÷ 60000
0: Disabled
1 ÷ 60000 s
Default
0
0: Disabled
Level
ENGINEERING
Address
855
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.
P256 PID Output Gradient Limit
P256
Range
1 ÷ 65000
1 ÷ 65000msec
Default
1
1msec

Address
856
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].
P257 Gain for PID Measure Scaling
P257
Range
0 ÷ 32000
0.000 ÷ 32.000
Default
1
1.000
Level
ENGINEERING
Address
857
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:
M023 = M020 * P257
M024 = M021 * P257
P260 Anti Wind-Up Gain
P260
Range
0 ÷ 100
0.00 ÷ 1.00
Default
100
1.00
Level
ENGINEERING
Address
860
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.
