It has the following functions: 1. Pulse compensation reduces the burden on the upper computer (because the equipment we use to send pulses, such as PLC, has restrictions on the frequency of sending pulses).
2. Match the number of pulses sent by the motor with the minimum mechanical motion, and the workpiece (or motor) motion of 1 pulse can be set to any value; It can realize stepless speed change of the motor, prevent out-of-step and overshoot when the motor starts and stops, and give full play to the potential of the motor.
3. Transfer synchronous motion information, realize coordinate linkage, conversion between motion forms (rotation-rotation, rotation-straight line, straight line-straight line), simplify control and so on.
Generally speaking, the motor is directly connected with the driving mechanism, and the transmission ratio is fixed after the mechanical structure is fixed; Using electronic gear can increase the flexibility of transmission system, reduce the number of transmission elements and the length of transmission chain, realize fractional transmission ratio, and thus improve transmission accuracy.
