Motion controller controls the general commissioning procedure of the servo motor with analog signals

Motion controllers control servo motors usually using two command methods:

1. Digital Pulse This method is similar to the control method of the stepping motor. The motion controller sends “pulse/direction” or “CW/CCW” type pulse command signal to the servo driver; the servo driver works in the position control mode and the position is closed loop. Completed by servo driver. Japanese servo and domestic servo products mostly adopt this mode. Its advantage is that the system is easy to debug, and it is not easy to produce interference, but the disadvantage is that the servo system responds slightly slower.

2. Analog signal In this mode, the motion control system sends a +/-10V analog voltage command to the servo driver and receives position feedback signals from position detectors such as a motor encoder or a linear encoder. The servo driver operates in the speed control mode. Position closed loop is completed by the motion controller. Most European and American servo products use this mode of operation. The advantage is that the servo response is fast, but the disadvantage is that it is more sensitive to on-site interference and the debugging is somewhat complicated.

The following describes the general debugging steps for the motion controller to control the servo motor with analog signals:
