Straight out of the Fanuc 0M B Maintenance manual:

417: When the X-axis enters any of the conditions shown in the following, this alarm results.

1) A Value which is out of the specified range has been set to the parameter 8120 for motor type

2) A proper value (111 or -111) has not been set to the parameter 8122 for the rotating direction of the motor

3) An improper data such as 0 or less has been set to the parameter 8123 for the number of velocity feedback pulses per rotation of the motor

4) An improper data such as 0 or less has been set to parameter 8124 for the number of position feedback pulses per rotation of motor.
