1KW 240V Servo Motor Drive Vfd For Ac Motor
According to the command mode and operation characteristics of a servo drive, it can be divided into three operation modes: position control operation mode, speed control operation mode and torque control operation mode.
1 The position control mode usually determines the displacement of the movement by the number of pulses, and the pulse frequency of the external input determines rotation speed. Because the position mode can strictly control the position and speed, it is generally used in the positioning device. It is the most popular control mode and mainly used in robot, table placement machine, carving and milling, CNC machines and so on.
2 The speed control mode controls rotation speed through the given analog quantity, the given digital quantity and the given communication speed. It is mainly used in the constant-speed applications. For example, the upper computer adopts position control mode and the servo drive adopts speed control mode in application of carving and milling machines.
3 The torque control mode controls torque through the given analog quantity, the given digital quantity and the given communication speed. It is mainly used in winding and unwinding devices which have strict requirements on the force of material, such as winding device or drawing fiber equipment and other tension control applications. The setting of torque should be changed at any time according to the radius of winding to ensure that the force of material will not change with the change of winding radius.
