Kinetix 6000 servo drive fault of E04, motor overtemp fault

I kept getting Kinetix 6000 servo drive fault of E04 (motor overtemp fault). The servo motor is MPL-B450F. The motor was barely warm, certainly not enough to trigger motor temp switch.

Two wires from the motor thermostat is terminated on the Kinetix wire terminal # 6 & 11 according to the online manual I found here. http://literature.rockwellautomation.com/idc/groups/literature/documents/um/2094-um001_-en-p.pdf
I'm attaching a screenshot from the manual.

Since the motor was not hot at all, we jumpered these two terminals and then we no longer get the E04. Had anyone have same experience?

BTW, I had to jumper the terminals AND leave the thermostat wires to the terminals (so two wires on each terminal), otherwise it wouldn't work. Doesn't make sense, I know.

E04 MotorOvertemp Fault (Motor Overtemp) Motor thermal switch tripped
• High motor ambient temperature
and/or
• Excessive current

Motor wiring error. Check motor wiring at MF connector on the IAM/AM
module.
Incorrect motor selection. Verify the proper motor has been selected.

These are other considerations from the manual.

I already checked the mf connector. no motor wiring error. Correct motor.

I would expect that the sensor is damaged. I would measure the mV signal and see if it is reasonable compared to the charts.
