[AJ-53]～[AJ-59]
Code/Name
AJ-53
PID4 proportional gain
AJ-54
PID4 integral time constant
AJ-55
PID4 derivative gain
・Sets the PID4 gain.
・If [PIDC] terminal is active (ON), the value of the
integral constant is purged. If done while operating, the
operation can become instable/insecure.
Code/Name
AJ-56
PID4 output range
PID output (%)

value
・Limits the output range of the PID. If [AJ-56]=0.00 the
limit is disabled.

AJ-57
PID4 deviation level
PID deviation (%)

Output
terminal ON
091[OD4]
・When the PID deviation pass over ±[AJ-57], the output
terminal function 091[OD4] is activated.
Code/Name
AJ-58
Maximum PID4 feedback
AJ-59
Minimum PID4 feedback
PID feedback (%)
0%
Operation
command
092[FBV4]
ON
・When the PID feedback cross over the [AJ-58] level, the
output terminal function 092[FBV4] is deactivated
(OFF). If it crosses under the [AJ-59] level, is activated
(ON).
