What is a motion controller? The difference between a motion controller and a PLC
1. What is a motion controller
A motion controller is a specialized controller that controls the operation mode of an electric motor. For example, the electric
motor drives an object up to a specified position and then down by controlling the AC contactor through a travel switch, or uses a
time relay to control the motor”s forward and reverse rotation or to stop and then stop again. The application of motion control in the
fields of robots and CNC machines is more complex than in specialized machines, as the latter have simpler motion forms and are
commonly referred to as General Motion Control (GMC).
2. Characteristics of motion controller
(1) The hardware composition is simple. Simply insert the motion controller into the PC bus and connect the signal lines to form the system;
(2) You can use the rich software already available on the PC for development;
(3) The code universality and portability of motion control software are good;
(4) There are many engineering personnel who can carry out development work and do not require too much training to proceed with development.
