■AH-50 = 05, 06 (minimum deviation, maximum deviation)
The maximum value or the minimum value of deviation 1 to 3 of
PID1 is taken as PID1 deviation (at this time, [AH-54] becomes
invalid).
・PID1 feedback calculated by setting [AH-51] to [AH-54].
・When 01 to 07 is selected in [AH-54], the operation target is
[AH-51] PID1 feedback data 1 (FB1) and [AH-52] PID1
feedback data 2 (FB2). When 08 to 10 is selected in [AH-54],
feedback data 1 ([AH-51] selection (FB1)) to 3 ([AH-53]
selection (FB3)) are targeted.

・If input terminal 042[PIDC] is active (ON), the value of
the integral constant is cleared. If it is done while the
inverter is in running, the driving condition may
become unstable.
・The PID gain can be switched by turning on the input
terminal 055[PRO]. When the [PRO] is ON, the gain 1 is
effective, and when the [PRO] is OFF, the gain 2 is
effective.
