Disconnection/short circuit check
When one or more of the following errors occur, perform a disconnection/short circuit
check for the resolver or motor.
Occurred error
9 Motor Test Error (Tilt)
10 Motor Driver Error (Rotate)
11 Motor Driver Error (Tilt)
16 Motor Test Error (Rotate)

15 Resolver Test Error (Tilt)
• Disconnection/short circuit check for the motor
Remove the terminal block 734-209-FUR from the TB1 (HFLT board) in the control
box, then measure resistance using a multimeter.
