Section V. Parameter Function Table
reduceintegrationtime so that system has fast response characteristic and smaller overshoot.
Notice
：
Improper PI parameter setting may lead to excessive speed overshoot , even voltage fault
during overshoot drop.
P2.06
Vector control slip gain 50%~200%
100%
☆
This parameter is used to adjust motor steady speed precision for zero-speed sensor vector control
mode. Please turn up the parameter value when with load motor running in low speed. On the contrary,
when the with load motor running in high speed, please turn down the parameter value.
This parameter is also used to adjust the output current value with the same load for speed sensor
vector control.
P2.07 Speed-loop filter time
0.000s~0.100s
0.000s
☆
In vector control mode, speed-loop regulator outputs torque current command. P2.07 is used to filter
the torque command.
Generally speaking, the parameter needs not to be modified. Users could properly increase the
filtering time when speed fluctuation is relatively big, and decrease the value when motor oscillation occurs.
If filtering time is small, inverter output torque might fluctuate greatly, but response speed will be fast.

0.0%~200.0% 150.0%
☆
In speed control mode, inverter maximum torque output is controlled by torque upper limit.
Range for 1-7 selections of P2.09 are corresponding to the setting range of P2.10.
P2.09 is used to select torque upper limit source. When P2.09 is set through analog, PULSE setup,
communication setup, which 100% corresponding to P2.10. 100% of P2.10 is the rated torque of the
inverter.

☆
Vector control current-loop PI regulation, which is automatically obtained after asynchronous motor
complete tuning or synchronous motor complete tuning. It generally needs not to be modified.
Caution
：
Integration regulator of current loop directly set integration gain without taking integration
time as the dimension. Excessive current loop PI gain may lead oscillation to the entire control loop circuit.
