Teco Drive Alarms

AL-01:

- This can be due to drive enable signal (through control cable), coming on prior to the drive having power (enable signal which powers up the drive through the contactor).  We have had a bad batch of control cables cause this issue.

AL-02:

If you are getting an AL-02 Over-Voltage on your drive you should check the motor power terminal continuity (Ohms):

- The main circuit voltage has exceeded its maximum allowable value (170 to 250 VAC)

- Check continuity between GND and each pin for the motor power. 

• For smaller motors (3 main pins inside the connection), GND will be the outside threads for the motor power cable
• For larger motors (4 main pins inside the connection), GND will be one of the pins. Shine a flashlight in to see the marking for which one is ground.
• If there is any continuity between GND and any of the U,V,W terminals, it is a bad motor causing the problem and will likely need to replace the drive as well.

AL-04:

-If you are getting an AL-04 Output Transistor Malfunction error on your drive after following the instructions in the drive error list, it is most often the drive which has gone bad. However, it could be the motor as well. If there is the same size motor you can do some cable swapping to determine if it is the motor or the drive.  Contact MachMotion for help in cable swap testing.

 

- Could be the Motor Code being wrong. Contact MachMotion.
