There are many methods to check the control circuit of a gear reducer motor, among which appearance inspection is one of them. How to observe the appearance change?

The appearance inspection mainly consists of the following four steps:

Step 1: Check if there is an insulation layer pressed into the terminal block. If there is an insulation layer pressed into the terminal block, it will make the circuit unable to be connected after being powered on;

Step 2: Check whether the exposed wire core meets the requirements;

Step 3: Shake and pull the wires on the wiring terminals by hand, check the contact between all wires and terminals, and do not allow any looseness;

Step 4: Use a multimeter to check the operation of each component and whether the wiring is correct.

Regarding the issue of checking the control circuit of the gear reduction motor, the next editor will show you how to check from the main circuit.
