User Manual of EM730 Series Inverter optional groups of parameters in total. The larger the set value of F06.37, the larger the proportional gain is, the smaller the integral time is, and the more intense the speed PID regulation is. The smaller the set value of F06.37, the weaker the speed PID regulation is. The default settings of low frequency optimization options of the synchronous motor are suitable for most applications. If a larger torque is required at the low frequency, you can enable the IF mode. Tuning parameters for speed tracking of the synchronous motor.
