Can a pulse signal from a PLC be given two steps at the same time?
If there is no independent control two stepper motor, a stepper motor running, another is running, a pulse signal of PLC can drive two stepper motors at the same time. Because the output of the transistor is sufficient to drive two steps into the motor drive, it is too much to say. In fact, the electrical current that enters the motor drive is only a few tens millian, the PLC transistor output capacity is 500 milliampere.
The impulse input of any step drive is a decoupling of the light, so theoretically the problem is small. But what is the purpose of this design? Synchronization?
In the case of the PLC output, the driver capacity is sufficient to drive the two-channel pulse input. If a driver is with the same brand, or wiring principle is the same, the same input voltage range, generally no damage, feel free to use, but the best telephone consultation with the manufacturer's technical support. If the brand, model, different batches, or wiring principle, internal resistance is different, although also can meet, but on the need to pay attention to many, it is difficult to describe.
First: your accuracy is low, and the speed is unpleasant. Second: two motors must be synchronized
