Chapter 5 Specification of Parameters
When P50.00 is set to 0, this parameter value is taken as set value of PID.
P50.02 PID feedback
Select the feedback source of PID control.

P50.03 PID adjustment

Unit's place: output frequency
0: Must be the same direction as setting running direction
When PID frequency output direction is opposite to run command direction, PID output is 0.
1: Opposite direction allowed
PID frequency output direction can be opposite to run command direction, and PID output
performs normally.

Decade: integration selection
0: Integral continued when frequency attains upper/lower frequency
Under PID control, when output frequency attains upper/lower limit of frequency or
parameter value of P50.23 (maximum frequency if it is opposite to command running direction),
PID integral continues. This mode requires longer time of quitting saturation.
1: Integral stopped when frequency attains upper/lower limit
Under PID control, when output frequency attains upper/lower limit of frequency or
parameter value of P50.23 (maximum frequency if it is opposite to command running direction),
PID integral will cease. This mode can quit integral saturation status rapidly.
PID positive and negative
P50.04
adjustment
0: Positive adjustment
1: Negative adjustment
This parameter can be used with digital input terminal "PID adjustment direction" to select
positive or negative adjustment of PID.
