・The PID2 function is enabled with the above parameter.
・If [AJ-01]=01 when the PID output reaches a negative
value, the PID output is limited to 0.
・If [AJ-01]=02 when the PID output reaches a negative
value, the PID output lets out an inverted output.
・By turning on the input terminal 043[PID2], the PID2
output becomes 0.

・The PID2 gains are set by the above parameters.
・If input terminal 044[PIDC2] 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.
