PA.04
PID setting feedback range
Default
1000
Setting Range
0 ~ 65535
This parameter is a non-dimensional unit. It is used for PID setting display (D0.15) and PID feedback display (D0.16).
Relative value 100% of PlD setting feedback corresponds to the value of PA.04. If PA.04 is set to 2000 and PID setting is 100.0%,
the PID setting display (D0.15) is 2000.
PA.05
Proportional gain Kp1
Default
20.0
Setting Range
0.0 ~ 100.0
PA.06
Integral time Ti1
Default
2.00s
Setting Range
0.01s ~ 10.00s
PA.07
Differential time Td1
Default
0.000s
Setting Range
0.00 ~ 10.000
PA.05 (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.
PA.06 (Integral time n1)
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 PA.06.
Then the adjustment amplitude reaches the maximum frequency.
PA.07 (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 feedback value change reaches 100.0%, and then the
adjustment amplitude reaches the maximum frequency.
PA.08
Cut-off frequency of PID reverse rotation
Default
2.00Hz
Setting Range
0.00 ~ maximum frequency
In some situations, only when the PID output frequency is a negative value (AC drive reverse rotation), PID setting and PID feedback
can be equal. However, too high reverse rotation frequency is prohibited in some applications, and PA.08 is used to determine
the reverse rotation frequency upper limit.
PA.09
PID deviation limit
Default
0.00%
Setting Range
0.00% ~ 100.0%
If the deviation between PID feedback and PID setting is smaller than the value of PA.09,PID control stops. The small deviation
between PID feedback and PID setting will make the output frequency stable and unchanging, especially effective for some closed-
loop control applications.
PA.10
PID differential limit
Default
0.10%
Setting Range
0.00% ~ 100.0%
It is used to set the PID differential output range. In PID control, the differential operation may easily cause system oscillation.
Thus, the PID differential regulation is restricted to a small range. PA.10 is used to set the range of PID differential output.
PA.11
PID setting changing time
Default
0.00s
Setting Range
0.00s ~ 650.00s
The PID setting changing time indicates the time required for PID setting changing from 0.0% to 100.0%. The PIO setting changes
linearly according to the changing lime, reducing the impact caused by sudden setting change on the system.
