PID parameter group 08
PARAMETER DESCRIPTION 228
If the user is given 8mA,then the corresponding proportion is given as (8-4)/ (20-4) * 08-43 (P.251).


When the input frequency has reached 01-03(P.3)*08-14(P.182), the value of 08-01(P.171) is 0 and the feedback
value < target value*08-07(P.175); or the value of 08-01(P.171) is 1 and feedback value > target
value*08-07(P.175); meanwhile the continuous time exceeds the value of 08-08(P.176), the PID can be
considered as abnormal and needed to be dealt with the setting value of 08-09(P.177).
For example: 08-07(
P.175
)=60%, 08-08
(P.176)
=30s, 08-09(
P.177
)=0,01-03
(P.3)
=50Hz, 08-14(
P.182
)= 100%, output
frequency reaches 50Hz, and feedback value is lower than 60% target feedback value for 30 seconds
continuously, alarm will trigger and inverter will stop freely.

If set 08-10(
P.178
) to 0, all 08-11(
P.179
), 08-12(
P.180
), 08-13(
P.181
) and 08-15(
P.183
) function are off. If
08-10(
P.178
) is not 0, turn on PID sleep function. If deviation between actual feedback value and target feedback
value is less than 08-10(
P.178
) sleep detection deviation for 08-11(
P.179
) sleep detection time, inverter will
gradually reduce the output frequency. When inverter output frequency is lower than 08-13(
P.181
) stop level,
inverter will decelerate and stop. When the setting value of 08-01(P.171) is 0 and the feedback value is lower than
wake-up level; or the value of 08-01(P.171) is 1 and the feedback value is higher than wake-up level, the output
frequency of the inverter will be controlled by PID again.
For example: 08-10(
P.178
)=5%, 08-11(
P.179
)=1.0s, 08-12(
P.180
)=90%, 08-13(
P.181
)=40Hz, 08-15(
P.183
)=0.5Hz,
If feedback value is greater than 95% and less than 105% of the target, inverter will reduce the output frequency
based on 0.5Hz per second. When
inverter output frequency is lower than 40Hz, inverter will decelerate and stop.
If feedback value is lower than 90% of the target, inverter will wake up and be controlled by PID again.
