[AJ-13]～[AJ-19]
Code/Name
AJ-13
PID2 proportional gain
AJ-14
PID2 integral time constant
AJ-15
PID2 derivative gain
・Sets the PID2 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-16
PID2 output range

・Limits the output range of the PID. If [AJ-16]=0.00 the
limit is disabled.

Output
terminal ON
047[OD2]
・When the PID deviation pass over ±[AJ-17], the output
terminal function 047[OD2] is activated.
Code/Name
AJ-18
Maximum PID2 feedback
AJ-19
Minimum PID2 feedback
PID feedback (%)
0%
Operation
command
048[FBV2]
ON
・When the PID feedback cross over the [AJ-18] level, the
output terminal function 048[FBV2] is deactivated
(OFF). If it crosses under the [AJ-19] level, is activated
(ON).

PID3 function
Code/Name
AJ-21
PID3
enable
・Validates the PID3 operation.
・If [AJ-21]=01 when the PID output reaches a negative
value, the PID output is limited to 0.
・If [AJ-21]=02 when the PID output reaches a negative
value, the PID output lets out an inverted output.
・By activating the [PID3] terminal, the PID3 output
becomes 0.

・You can switch the display data and the display unit
involved in the output of the PID control by the
calculation.
