Code Description
2 M/(G*A)
3 M+(M*(G*A))
4 M+G*2*(A-50)
5 M*(G*2*(A-50))
6 M/(G*2*(A-50))
7 M+M*G*2*(A-50)
8 (M-A)^2
9 M^2+A^2
10 MAX(M,A)
11 MIN(M,A)
12 (M+A)/2
13 Square Root(M+A)
M= Value by the source set at PID-30
G= Gain value set at PID-33
A= Value by the source set at PID-31
PID-23 PID Fdb Aux G Gain value used a formula set at PID-22.
PID-24
PID Fdb Band
Sets the maximum and minimum value by adding or subtracting the PID
Fdb Band value (set at PID-24) from the reference value. When the feedback
value is between the maximum and minimum value, this code maintains the
PID output.
PID-25
PID P-Gain1
PID-32
PID P-Gain2
Set the output ratio for differences (errors) between the reference and
feedback. If the P Gain is set to 50%, then 50% of the error is output.
PID-26
PID I- Time 1
PID-33
PID I- Time 2
Sets the time to output accumulated errors. When the error is 100%, the time
taken for 100% output is set. When the integral time (PID I-Time) is set to 1
second, 100% output occurs after 1 second of the error remaining at 100%.
Differences in a normal state can be reduced by PID I Time. When the multi-
function terminal block is set to ‘24 (I-Term Clear)’ and is turned on, all of the
accumulated errors are deleted.
PID output (final frequency reference) is affected by the gains set at PID-26,
PID-33, and the Acc/Dec times to achieve the PID output change based on
the DRV-03 and DRV-04 settings. Therefore, consider the relationship
between these values when configuring the gains and the Acc/Dec times.
PID-27
PID D-Time 1
PID-34
PID D-Time 2
Sets the output volume for the rate of change in errors. If the differential time
(PID D-Time) is set to 1 ms and the rate of change in errors per sec is 100%,
output occurs at 1% per 10 ms.
