Details
The servo amplifier is in a normal state (communication with
the servo amplifier can be performed).
Servo amplifier is not loaded. The servo amplifier control
circuit power supply is turned OFF. Because of a failure
with the connection cable, communication with the servo
amplifier cannot be performed.
