VFS11-4110 Related Differences
1. The servo controller can easily switch between the operation module and the field bus module through the automatic interface, and at the same time, different field bus modules are used to realize different control modes (RS232, RS485, optical fiber, InterBus, ProfiBus), while the control mode of the general frequency converter is relatively single.
2. The servo controller is directly connected to the resolver or encoder to form a closed loop of speed and displacement control. The general frequency converter can only form an open-loop control system.
3 All control indexes of servo controller (such as steady-state accuracy and dynamic performance, etc.) are better than those of general frequency converter.
