I have a problem with a Hitachi Seiki ht30j lathe cnc.
The machine has an error code 3421 ( Inverter code problem), the inverter has his own alarm AL-60. The manual's inverter it says that it can be: faulty encoder PCB board, spindle encoder or spindle motor.
I have contacted yaskawa, they say I have to send the motor to be fixed. But because the motor is build on the machine can't be done.
Does someone has this problem?
