Faced with the problem of stepper motor interference to be handled this way
- Jan 17, 2018 -

In many occasions, because the stepping motor current voltage is high, such as some stepping motor maximum output current of 8A, voltage 325V, coupled with its shell is not the use of aluminum alloy shell for magnetic shielding, so highly sensitive receiver system Cause interference, make it unable to work, and interfere with the power, especially at high frequency, may cause the control system of the microcontroller and the host computer can not be normal communication, causing serious SCM crashes, causing difficulties for normal use, so interference problems must be solve.

Faced with the problem of stepper motor interference to be handled this way

 

1, install the power filter to reduce the pollution of AC power.

 

2, "a little grounding" principle. Connect the mains filter ground, the driver PE (ground) (the driver is insulated from the chassis base), the control pulse PULSE- and the directional pulse DIR- after the shorted lead wire, the motor ground wire, the cable gland between the driver and the motor, the driver Shielded cable are connected to the chassis wall grounding column, and requires good contact.

 

3, try to increase the control line and the power line (L, N), motor drive line (U, V, W) the distance between, to avoid cross. For example, when we are dealing with two drive installations in the same chassis in a two-axis drive system, one drive faces the front with the nameplate facing forward and the other one facing back, minimizing the structural layout of the leads.

 

4, the use of shielded cable to reduce external interference on their own, or their own (power cord) on the outside world interference.
