Activates when the total servo current time
exceeds the specified value.
Activates when an overcurrent flows to the motor
circuit.
Activates when the encoder cable is discon-
nected.
Activates when an error occurs between the com-
mand value and actual position, and the error
exceeds the specified amount.
Activates when the AC power voltage drops below
the specified value.
Activates when an error occurs in the CPU.
