PID parameter group 08
PARAMETER DESCRIPTION 234
5.9.11 PID reverse run operation selection

PID reverse run selections is used to set whether reverse run is allowed when PID calculation result is negative.
Parameter Name Default Setting Range Content
08-40
P.727
PID allowed reverse
rotation action
selection
1
0 PID does not allow reverse
1 PID allow reverse
08-41
P.728 PID in reverse
direction integral limit
0.0% 0 ~ 100.0%
It is used to set the upper limit of PID integral when run
reverse. Set to 0 when reverse run is not allowed.
08-42
P.729 PID minimum output
frequency
0.00Hz 0 ~ 10.00Hz
It is used to set the minimum PID output
PID reverse run operation selection

When PID allows reverse run, 08-41(P.728) should be set greater than 0, generally set to 100.0%. If PID does not
allow reverse run, 08-41(P.728) set 0.

08-42(P.729) is used to set the lowest output frequency in PID calculation. If output is less than 08-42(P.729) ,
inverter stops output.
5.9.12 Pressure unit (Bar) setting
Used by setting the maximum value of PID target value.
Param

Name Default Setting range Content
08-43
P.251 PID pressure range
(Bar) setting
100.0
1.0~100.0 Set the maximum value of PID target value.
Pressure unit (Bar) setting

Example: if the pressure sensor feedback range is 0~10V and the corresponding pressure range is 0~16.0 bar,
then set 08-43（P.251） to 16.0.
5.9.13 PID unit selection
The unit of PID pressure displayed when used with PU301C.
