A06B-6102-H245 is typically used with Fanuc 16MC, 16MA, 18TA, 18MC, 21TB, 16TB, 18TB, and 21MB controls.
Typically found on machines such as Youji YV1200

A06B-6102-H245 Alarm 12 and Alarm 03 Troubleshooting Steps
(1) Power off the machine. Remove the power line wires from the spindle amplifier terminals, and be sure to place them so that there is no chance or shorting out something in the electrical cabinet. Power ON the machine/ control and command the spindle. 
If Alarm 12 occurs, go to (3). If not, go to (2). 

(2) Check for insulation between PE and each of the removed power wires U, V, and W.  Good/ acceptable insulation is in the order of several HUNDRED MEGA OHMS or higher.  
If not, disconnect the power wires from the motor.  Then check for insulation again between PE and each of the U, V, and W terminals on the motor itself. If there is a short circuit between PE and  U, V, or W of the motor, replace the motor. 
If motor insulation is tested good, replace the motor power wires.
