[AJ-33]～[AJ-39]
Code/Name
AJ-33
PID3 proportional gain
AJ-34
PID3 integral time constant
AJ-35
PID3 derivative gain
・Sets the PID3 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-36
PID3 output variable
PID output (%)

・Limits the output range of the PID. If [AJ-36]=0.00 the
limit is disabled.

047[OD3]
・When the PID deviation pass over ±[AJ-37], the output
terminal function 089[OD3] is activated.
Code/Name
AJ-38
PID3 feedback compare
signal turn-off level
AJ-39
PID3 feedback compare

Operation
command
048[FBV3]
ON
・When the PID feedback cross over the [AJ-18] level, the
output terminal function 090[FBV3] is deactivated
(OFF). If it crosses under the [AJ-39] level, is activated
(ON).

AJ-41
PID4
enable
・Validates the PID4 operation.
・If [AJ-41]=01 when the PID output reaches a negative
value, the PID output is limited to 0.
・If [AJ-41]=02 when the PID output reaches a negative
value, the PID output lets out an inverted output.
・By activating the [PID4] terminal, the PID4 output
becomes 0.
