Switching power supply is 12 v 4.5 A, power supply for two drives, two stepper motor drive current is 1 A, step electric opportunities appear accidental jitter problem, if use two power supply for each drive power supply respectively, will not shake, what's the problem?

The same thing: a power supply for stepping drive at the same time, and the electromagnetic valve power supply, if the electromagnetic valve conduction, stepper motor started shaking, did not shake off solenoid valve motor,

The above two questions should be the same reason, but don't know is what reason, how to troubleshoot?

CodePudding user response:

Complement, electromagnetic valve is controlled by relay, stepper drives and relay are controlled by the STM32,
