Teach you how to solve the problem of step motor interference: 1, equipped with power supply filter, reduce the pollution for the ac power. Stepper motor 2, the principle of 'ground'. Will the power filter, driver (PEGround)(Drive and chassis backplane insulation)And the control PULSE PULSE -DIR - pulse and directionSub pinout, stepper motor, drive and motor cable between protective grounding line, shielded wire drive all received chassis grounding on the column wall, and requires good contacts. Stepper motor 3, increase the line of control and the power cord (as far as possibleL, N), motor drive line (U, V, W)The distance between the, avoid cross. Such as we in the process of twin screw drive system is in the same case of drives to install two locations, a drive plate in the front, the other is the later, and these lead to short on the structure arrangement. 4, use the shielded wire reduce outside interference to himself, or his (The power cord)Interference with the outside world the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
