Tac 32 Evo Controller, traditional traction machine only runs for about .5 seconds and has an "Torque Limit Fault". Motor is only 2 years old car has been moded. Counter weight was added for addition of new weight.
Accord Drive 663 fault - XS_Torque_Limit - The torque current is greater than 2.5 times the motor nominal current for .5 seconds (if running elevator on Inspection or Automatic Operation.
Things I've done
- Motor Windings ohmed good (9 wire motor multi voltage, wired for high voltage)
- Brake is fully picking
- Safties are not dragging
- 35 amp motor rating, each leg on in-rush current is 28 amps or less.
- The car moves about an inch in each direction before it faults.
- Motor shaft spins 1 1/2 rotations before it faults.
- It has oil and was greased recently (from what I can see)
- They put in a flex coupler with new motor.
Planning to do
- I'm going to pick the brake and see if the car drifts to ultimately tell if it is mechanically bound at all.
- Try and find the parameter settings to increase the time or current to see if I can get it to pull through what ever it is preventing or causing issues as the machine may be seizing and I will get some feed back and noise to narrow in.
Personally I think this is a drive issue, but I need to finish preliminary testing.
My question to to everyone is, has anyone seen this fault and if so was it associated with the Accord drive? Before I go bonkers.
Thank you!
