enable
・The PID4 function is enabled with the above parameter.
・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 turning on the 047[PID4] terminal, the PID4 output
becomes 0.

PID4 derivative gain
・The PID4 gains are set by the above parameters.
・If input terminal 048[PIDC4] 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.
