Control parameter

11-00(P.320) and 11-01(P.321) are PI adjustment parameters when operating frequency is less than switching
frequency 1 (11-02(P.322)), while 11-03(P.323) and 11-04(P.324) are PI adjustment parameters when the
operating frequency is greater than switching frequency 2 (11-05(P.325)). The PI parameters of the frequency
band between switching frequency 1 and switching frequency 2 are linear switching of two groups of PI
parameters. As shown in the following diagram:


11-00(P.320) / 11-03(P.323) is used to set the proportion gain of speed control.(Set the value slightly larger to
better follow changes on the speed reference and to reduce speed change due to external interference.)

11-01(P.321) / 11-04(P.324) is used to set the integral time of speed control.(Due to external
interference-generated speed change, set the value smaller to shorten the time spent on returning to the original
speed.)

When 11-06(P.326) is set to 100%, the max output torque in vector control is the motor rated torque.
