can select MS V/F running mode when performing prototyping test.
The controlled object has certain dynamic and static index requirements: This kind of load
requires harder mechanical characteristics at low speed in order to satisfy the dynamic and
static index requirements of the process for the control system. It can select SVC control mode.
The controlled object has higher dynamic and static index requirements: It can employ VC
control mode in applications where the requirements for speed adjustment precision and
dynamic performance index are relatively high and there is high precision synchronous control.
