Chapter 6 Parameter Description
98
1: Continue integration adjustment: The integration value will give immediate response to the change
between the reference value and the feedback value unless this value reaches the internal integration
limit. When there is change occurring to the deviation between the reference value and the feedback
value changes, it needs to take longer time to offset the impact brought by the continuous integration so
that the integration value can catch up that change trend.
If the output value of the close loop adjustment is inconsistent with the current setup running direction,
the close loop output value has two actions for selection.
0: It must be consistent with the setup running direction: When the output value of the close loop
adjustment is inconsistent with the current setup running direction, the current output value will be forced
to be 0 internally.
1: It can be against the setup running direction: When the output value of the close loop adjustment is
inconsistent with the current setup running direction, the close loop adjustment opposite to the current
setup running direction will be executed.
PID is positeve function at default. It needed negative function when feedback value is greater than
reference value and the frequency needed increase. This function can realized through setting P8.09=1
or multi-function terminal function setting as 68.
P8.09=0, Terminal function is invalid: Positive;
P8.09=1, Terminal function is valid: Positive;
P8.09=1, Terminal function is invalid: Negative;
P8.09=0
，
Terminal function is valid: Negative.
6.10 Motor Parameter (Group P9)
This function is used to determine the motor load type driven by the inverter.
0: G-type constant torque/heavy-duty application
1: L-type variable torque/heavy-duty application
Once the load type is changed, P9.03 ~ P9.14 will change to the factory default setting automatically,
while P3.01 and P3.07 will change to 0 automatically. When the load type is selected as 1, the current
limit value PA.05 will change to 120% automatically, while the drive and brake torque limit values Pd.08
and Pd.09 will change to 135% automatically. When the load type is selected as 0, the current limit value
PA.05 will change to 160% automatically, while the drive and brake torque limit value Pd.08 and Pd.09
will change to 180% automatically.
