Answer: Before power-on operation, the following checks should be made:
1. Whether the power supply voltage is appropriate (overvoltage is likely to cause damage to the drive module); The +/- polarity of the DC input must not be connected incorrectly, whether the motor model or current setting value on the drive controller is appropriate (not too large at the beginning);
2. The control signal line is firmly connected, and it is best to consider the shielding problem in the industrial site (such as using twisted pair);
3. Do not connect all the wires that need to be connected at the beginning, only connect to the most basic system, and then connect them gradually after running well.
4. Be sure to figure out whether to ground the grounding method or use floating without connecting.
5. Within half an hour of starting operation, closely observe the state of the motor, such as whether the movement is normal, sound and temperature rise, and stop and adjust immediately if the problem is found.
