Chapter 6 Description of Function Codes

Determines how strongly the PID regulator adjusts the deviation rate of change. The longer
the differentiation time, the greater the adjustment intensity. Differential time means that when
the feedback amount changes 100.0% within this time, the adjustment amount of the differen-
tial regulator is the maximum frequency.

☆
In some cases, only when the PID output frequency is negative (that is, the inverter is revers-
ed), can the PID control the given amount and the feedback amount to the same state, but
too high reverse frequency is not allowed in some occasions Yes, PA-09 is used to determi-
ne the upper limit of the reverse frequency.

PA-10 Deviation limit

☆
When the deviation between the PID given amount and the feedback amount is less than
PA-10, the PID will stop adjusting. In this way, when the deviation between the given and the
feedback is small, the output frequency is stable and unchanged, which is very effective for
some closed-loop control occasions.

PA-11 Differential clipping 0.00% ～ 100.00% 0.0%
☆
In the PID regulator, the role of differential is more sensitive, and it is easy to cause system
oscillation. For this reason, the role of PID differential is generally limited to a small range.
PA-11 is used to set the range of PID differential output.

PA-12 PID feedback filter time 0.00 ～ 60.00s 0.00s
☆
PA-12 is used to filter the PID feedback amount, which is beneficial to reduce the influence of
the feedback amount by interference, but it will bring the response performance of the proce-
ss closed-loop system.
