・The PID sleep function temporally reduces the PID
output, achieving an energy saving state.
・If [AH-88]"Enable set-point boost before PID sleep" is
enable, during [AH-89] setting time before PID sleep,
the [AH-90] boost amount is added to the PID target
value to increase the feedback amount.
As a result, it is possible to maintain sleep for a longer
time.
・Operation example of the sleep function.
Example 1) [AH-85]=01(Low output)
[AH-93]=01(deviation)
Example 2) [AH-85]=01(Low output)
[AH-93]=02(Low feedback)
Example 3) [AH-85]=02(output terminal 058[SLEP])
[AH-93]=03(output terminal 059[WAKE])
■There are 4 independent PID control blocks in P1.
By switching the input terminal 056[PIO1]/057[PIO2],
PID1 to PID4 can be switched.
