PA.22
PID initial value holding time
Default
0.00s
Setting Range
0.0s ~ 650.00s
When the AC drive starts up, the PID starts closed-loop algorithm only after the PID output is fixed to the PID initial value (PA.21)
and lasts the time set in PA.22.
Figure 4-25 PID initial value function
PA.23
Maximum deviation between two PID outputs
in forward direction
Default
1.00%
Selling Range
0.00% ~ 100.00%
PA.24
Maximum deviation between two PID outputs
in reverse direction
Default
1.00%
Setting Range
0.00% ~ 100.00%
This function is used to limit the deviation between two PID outputs (2 ms per PID output) to suppress the rapid change of PID
output and stabilize the running of the AC drive.
PA.23 and PA.24 respectively correspond to the maximum absolute value of the output deviation in forward direction and in
reverse direction.
PA.25
PlD integral property
Default
00
Setting Range
Unit's digit
Integral separated
0
Invalid
1
Valid
Ten's digit
Whether to stop integral operation when
the output reaches the limit
0
Continue integral operation
1
Stop integral operation
Integral separated
If set the integral separated valid, the PID integral operation stops when the X allocated with function 38 "PID integral pause" is
effective. In this case, only proportional and differential operations take effect.
If it is set invalid, integral separated remains invalid no matter whether the S allocated with function 38 "PIO integral pause" is ON
or not.
Whether to stop integral operation when the output reaches the
limit.
If "Stop integral operation" is selected, the PIO integral operation stops, which may help to reduce the PID overshoot.
PA.26
Detection value of PID feedback loss
Default
0.0%
Setting Range
0.0%: Not judging feedback loss
0.1%: 100%
