Woodworking engraving machine manufacturers - how to solve the engraving machine stepper motor and driver interference
A. The Jinan engraving machine is equipped with a power filter to reduce the pollution of the AC power supply.
B. "One point grounding" criterion. The ground of the power filter, the driver PE (ground) (the driver is insulated from the chassis bottom plate), the pilot pulse PULSE- and the direction pulse DIR- shorted lead wire, the motor ground wire, the cable protection sleeve between the driver and the motor, the driver The shielded wires are connected to the grounding post on the wall of the chassis and require good contact.
C. Try to increase the distance between the control line and the power line (L, N) and the motor drive line (U, V, W) to prevent insertion. For example, we are dealing with two drive units in the same chassis in the dual-axis drive system. In orientation, one drive nameplate faces forward and the other faces backwards, and the construction is arranged to keep these leads as short as possible.
D. Use shielded wires to alleviate the disturbances of the outside world, or to disturb the outside world by yourself (power cord)
