oscillation, generally the role is limited to a smaller range, E2.07 is used to set PID differential
output range.
E2.08
PID reference change time
0.00s to 650.00s
0.00s
☆
The PID reference change time means the required time that PID reference value changes
from 0.0% to 100.0%.When the PID reference changes, the PID reference value will change
linearly according to the reference change time to reduce the adverse effects to the system
caused by a sudden reference change.
E2.09
PID feedback filter time
0.00s to 60.00s
0.00s
☆
E2.10
PID output filter time
0.00s to 60.00s
0.00s
☆
E2.09 is used for filtering the PID feedback quantity, the filter helps reduce the influence
of interference to the feedback quantity, but will bring the response performance of the process
closed loop system.
E2.10 is used for filtering the PID output frequency, the filter will weaken the sudden
change of the inverter output frequency, but it will also bring the response performance of the
process closed loop system.
E2.11
PID feedback loss detection value
0.0%: Not judged feedback loss
0.0%
☆
0.1% to 100.0%
E2.12
PID feedback loss detection time
0.0s to 20.0s
0s
☆
This function code is used to determine whether the PID feedback is lost or not.When the
PID feedback is less than the PID feedback loss detection value(E2.11), and the duration is
longer than the PID feedback loss detection time(E2.12), the inverter will alarm fault ID Err.31,
and troubleshoot according to the selected method.
E2.13
Proportional gain KP1
0.0 to 200.0
80.0
☆
E2.14
Integration time Ti1
0.01s to 10.00s
0.50s
☆
E2.15
Differential time Td1
0.000s to 10.000s
0.000s
☆
Proportional gain KP1:Used to decide the extent of the PID regulator, the greater KP1, the
greater adjusting extent. This parameter 100.0 means that when the deviation of PID feedback
value and reference value is 100.0%, the PID regulator will adjust the output frequency
command to the maximum frequency.
Integration time Ti1: used to decide the extent of integral adjustment of the PID regulator.
The shorter integration time, the greater extent of integral adjustment The integration time
means that when the deviation of PID feedback value and reference value is 100.0%, the
integration regulator will successively adjust to the maximum frequency for the time.
Differential time Td1: used to decide the extent that the PID regulator adjusts the deviation
change rate. The longer differential time, the greater extent of adjustment The differential time
means that the feedback value changes 100.0% within the time, the differential regulator will
adjust to the maximum frequency.

In some applications, only one group of PID parameters can not meet the needs of the
entire run, it is required to use different PID parameters under different conditions.
This group of function codes is used to switch between two groups of PID parameters.
Which the setting method for regulator parameter(E2.16 to E2.18) is similar to the
parameter(E2.13 to E2.15).The two groups of PID parameters can be switched by the multi-
functional digital DI terminal, can also be switched automatically according to the PID
deviation.If you select the multi-functional DI terminal, the multi-function terminal function
