During the use of linear modules, many common issues often arise, leaving managers unsure of how to proceed. To address this, our engineers at Rui Xiang have compiled a "Common Troubleshooting and Solutions" guide. Due to its length, it will be divided into several parts. Business owners can refer to these sections based on their specific situations.
1.
Issue: Motor overheating severely
Possible Causes: Driver current setting exceeds motor rated current.
Solution:
1. Adjust the driver current to match the motor current.
2. It is normal for the surface temperature of stepper motors to be between 80-90 degrees Celsius.
2.
Issue: Motor makes noise upon power-up, but the lead screw does not rotate
Possible Causes:
1. Incompatibility between driver and motor
2. Insufficient motor torque
3. Acceleration and deceleration times not set in control
4. Loose coupling or eccentricity between motor shaft and lead screw
Solution:
1. Replace with suitable motor and driver matching the motor's rated power and adjust the current accordingly.
2. Set acceleration and deceleration times in the control (around 0.35s).
3. Adjust the coaxiality between motor and lead screw and tighten the coupling.
3.
Issue: Lead screw jams intermittently
Possible Causes:
1. Insufficient motor torque
2. Acceleration and deceleration times not set in control
3. Loose coupling or eccentricity between motor shaft and lead screw
4. Lack of lubrication between lead screw and nut
Solution:
1. Set acceleration and deceleration times in the control.
2. Adjust the coaxiality between motor and lead screw and tighten the coupling.
3. Apply lubricating oil.
4.
Issue: Motor feels insufficient torque, lead screw sometimes cannot turn
Possible Causes:
1. Insufficient motor power
2. Incompatibility between driver and motor
Solution:
1. Adjust the driver current to match the motor current.
2. Replace with a suitable driver.
5.
Issue: Oscillation during operation
Possible Causes:
1. Low-speed operation with low microstepping
2. Overloaded operation not meeting customer requirements
Solution:
1. Increase driver microstepping during low-speed operation.
2. Replace with a smoother and more suitable solution.
Encountering faults during industrial operations is normal, but knowing how to use and troubleshoot effectively is crucial for improving operational efficiency. These common and easily solvable issues cover various scenarios, allowing business owners to identify their specific problems and apply appropriate solutions promptly.
