F0.03
PID setting feedback range
Range:0.0
～
6000.0
Default:100.0
This parameter is a non-dimensional unit. It is used for PID setting display (U0.11) and PID
feedback display (U0.12).Relative value 100% of PID setting feedback corresponds to the value of
F0.03. If F0.03 is set to 1000 and PID setting is 50.0%, the PID setting display (U0.11) is 500.
F0.04
PID action direction
Range:0
～
1
Default:0
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.

Positive adjustment:
When feedback signal is smaller than PID setting, output frequency of the drive will rise to reach
PID balance.
When feedback signal is bigger than PID setting, output frequency of the drive will drop to reach
PID balance.
Negative adjustment:
When feedback signal is smaller than PID setting, output frequency of the drive will drop to reach
PID balance.
When feedback signal is bigger than PID setting, output frequency of the drive will rise to reach
PID balance.

Proportional gain Kp1:
It decides the regulating intensity of the PID regulator. The higher the Kp1 is, the larger the
regulating intensity is. The value 100.0 indicates when the deviation between PID feedback and PID
setting is 100.0%; the adjustment amplitude of the PID regulator on the output frequency reference is
the maximum frequency.
Integral time Ti1:
It decides the integral regulating intensity. The shorter the integral time is, the larger the regulating
intensity is. When the deviation between PID feedback and PID setting is 100.0%, the integral
regulator performs continuous adjustment for the time set in F0-06. Then the adjustment amplitude
reaches the maximum frequency.
Differential time Td1:
It decides the regulating intensity of the PID regulator on the deviation change. The longer the
differential time is, the larger the regulating intensity is. Differential time is the time within which the
