A series of checks should be carried out before the stepper motor is used，To ensure it works properly and avoid potential problems。Here are some key things to check：

one、Power supply and driver check

1. Supply voltage check：

• Ensure that the supply voltage is consistent with the voltage required by the stepper motor driver，Avoid over-pressure or under-pressure situations，Because overpressure is likely to cause damage to the drive module。

• Stepper motor for DC input，Attention check+/-Correctness of polarity，Do not misconnect。

2. Drive Settings check：

• Check that the motor type or current setpoint on the stepper motor driver is appropriate，Dont start with a large setting，To avoid damage to the motor or drive。

two、Control signal and connection check

1. Control signal cable connection：

• Ensure reliable connection of control signal cables，No loosening or poor contact。

• At the industrial site，It is best to consider the shielding of signal lines，Such as the selection of twisted pair shielding measures，To reduce electromagnetic interference。

2. Stepwise connection：

• Dont connect all the wires that need to be connected at first，It is recommended to connect only the most basic system at first，After the operation is good, then gradually connect other parts。

three、Motor condition and installation check

1. Motor fixation：

• Make sure the stepper motor is securely secured，Unsecured motors may have strong resonance during operation，Cause out of step or damage。

2. Initial operational observation：

• Within half an hour of being up and running，Closely observe the state of the motor，Including whether the exercise is normal、Sound and temperature rise。If an anomaly is found，Stop immediately for adjustment。

four、Other examination

1. Grounding check：

• Figure out the grounding method，Choose whether to use floating or other grounding methods based on the actual situation。

2. Motor parameter check：

• According to the data shown on the motor nameplate（Such as voltage、power、frequency、join、Speed dispatch），And power supply、Load comparison，Make sure they match exactly。In case of discrepancy，Need to be adjusted。

3. Ventilation and lubrication check：

• Check the ventilation of the motor，Ensure that the motor is running under good ventilation，Avoid overheating。

• Check bearing lubrication，In case of poor lubrication, lubricating oil should be added in time。

To sum up，The stepper motor should be fully inspected before use，Power supply and driver included、Control signals and connections、Check motor condition and installation and other related aspects。Through these checks，It can ensure that the stepper motor runs in normal working condition，Reduce the risk of failure and damage。
