Electric drag refers to a method of using a motor to drive the working mechanism of a production machine to operate. It includes power supplies, motors, control equipment, and transmission mechanisms. In order to complete a certain process in the machine, the motor is required to complete different rotation modes according to the process requirements, and the control equipment is connected to meet the requirements by a certain type of line, and these lines are electric drive control lines.
It includes: jog line, continuous running circuit, positive and negative circuit, multi-ground control circuit, step-down starting line, multi-speed asynchronous motor control line, position control line and so on. These are all electric drag control lines.
