Disconnection/short circuit check
When one or more of the following errors occur, perform a disconnection/short circuit
check for the resolver or motor.
• 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.
• Disconnection/short circuit check for the resolver
Remove the terminal block 733-106-FUR and 733-110-FUR from the TB8 and TB10
in the control box, then measure resistance using a multimeter.
