Exceptions and solutions

TPA ROBOT guarantees that the quality of our delivered products is the best. Even so, we cannot 100% guarantee that our actuators will not have any problems. When you notice any abnormalities in the actuators, please stop using them immediately, and Follow the steps below to troubleshoot and easily resolve failures or exceptions.

If you still cannot solve the existing fault or abnormality, please call our after-sales engineer or sales: info@tparobot.com, or fill out the form, we will immediately respond to your request and assist you to solve the problem.

Abnormal solutions for ball screw driven actuators/electric cylinders:

Applicable Models	Exceptions	Solutions
GCR Series GCRS Series KSR/KNR Series HCR Series HNR Series ESR Series EMR Series EHR Series	Abnormal sound when power is connected	a. Adjust the value of the parameter "Mechanical Resonance Suppression" in the servo drive. b. Adjust the value of the parameter "Auto-Tuning" in the servo drive.
	Abnormal noise when the motor turns	a. Adjust the value of the parameter "Mechanical Resonance Suppression" in the servo drive. b. Adjust the value of the parameter "Auto-tuning" in the servo drive. c. Check whether the motor brake is released. d. Check whether the mechanism is deformed due to overload.
	The slider/rod is not smooth when the motor is running	a. Check whether the brake is released; b. Separate the motor from the linear actuator/electric cylinder, push the sliding seat by hand, and judge the cause of the problem. c. Check whether the fixing screw of the coupling is loose. d. Check whether there is foreign matter falling in the moving area of the linear actuator/electric cylinder.
	The walking distance of the linear module/electric cylinder rod does not match the actual distance	a. Check whether the input travel value is correct. b. Check whether the lead input value is correct.
	The slider/rod does not move when the motor movement is ON	a. Check if the brake is released. b. Check if the coupling fixing screw is loose. c. Separate the motor from the linear actuator/electric cylinder, and determine the problem and cause.

Abnormal solutions for belt driven actuators:

Applicable Models	Exceptions	Solutions
HCB Series HNB Series OCB Series ONB Series GCB Series GCBS Series	Abnormal sound when the power is connected	a. Adjust the value of the "mechanical resonance suppression" parameter in the servo drive b. Adjust the value of the parameter "auto-tuning" in the servo drive
	Coupling, timing pulley slipping	a. Check the timing pulley and whether the coupling is locked b. Check the timing pulley and whether the coupling has a keyway c. Whether the shafts of the timing pulley and the coupling match.
	Slider motion is not smooth when the motor is running	a. Check if the brake is released b. Separate the motor from the linear module, push the sliding seat by hand, and determine the cause of the problem c. Check whether the coupling fixing screws are loose d. Check whether there are foreign objects falling in the moving area of the linear module
	Actuator motion positioning is not accurate	a. Check whether the belt is slack and skipped teeth b. Check whether the input value of the belt lead is correct
	Servo motor alarm, indicating overload	a. Check whether the brake is released b. Check whether the coupling fixing screws are loose c. If because of installing reducer, increase the speed ratio, increase the torque, and reduce the speed

Abnormal solutions for direct drive linear motors:

Applicable Models	Exceptions	Solutions
Direct drive linear motors (LNP series LNP2 series P series UH series)	Motor overrun	1. The motor exceeds the limit position; 2. Adjust the motor parameters; a. Overall reset after restarting the software; b. Check whether the length of the connecting rod between the motor and the walking arm is appropriate.
	Could not find motor origin	1. The motor exceeds HM; 2. Manually move the walking arm and observe the position of the motor; a. Replace the reading head, restart and reset b. Check whether the surface of the magnetic scale is damaged, if so, replace the magnetic scale.
	Can't reset	1. Software problems; 2. Re-download the motor board driver test; a. Replace the driver board; b. Check whether the driver board and the peripheral wiring of the motor are loose.
	CAN bus communication alarm	a. Check if the CAN Bus wiring is loose; b. Unplug the bus connector on the PC board, if there is dust, plug it back in after cleaning and test; C. Replace the driver board and download the program again.
	Abnormal noise and vibration	1. Check the corresponding mechanical parts, make adjustments, and replace spare parts if necessary; 2. Adjust the motor PID parameters.
