Data Description
PID disable function [PID] 041
Disables the PID1 function by turning ON the
terminal function. When disabled, operation is done
by using the command set for target value as
command frequency.
PID1 I control integral value clear [PIDC] 042 Clears integral value of PID1 control.
Multi-layer target command terminal 1 [SVC1] 051
Switches multiple target values.
Multi-layer target command terminal 2 [SVC2] 052
Multi-layer target command terminal 3 [SVC3] 053
Multi-layer target command terminal 4 [SVC4] 054
PID gain switch [PRO] 055 Switches PID gain 1 and 2 by terminal.
Item Parameter Data Description

Displays PID1 target value.
Is changeable when [AH-07] = 07 or
multi-layer target value 1-15 is enabled.
PID1 target value 2 [FA-32] -100.00~100.00(%)*1)
Displays PID1 target value 2.
Is changeable when [AH-42] = 07.
PID1 target value 3 [FA-34] -100.00~100.00(%)*1)
Displays PID1 target value 3.
Is changeable when [AH-46] = 07.
PID1 feedback monitor 1 [db-30] -100.00~100.00(%)*1) Displays PID1 feedback value 1.
PID1 feedback monitor 2 [db-32] -100.00~100.00(%)*1) Displays PID1 feedback value 2.
