*1. Servo Ready (READY) turns ON and returns a response when these conditions are met: MPU initialization is
completed, main power is established, no alarms exist, MECHATROLINK-II communications are established, and
the servo is synchronized.
*2. Once the internal control power is established, the protective function starts working about 1.5 s after the CPU starts
initializing itself.
Be sure that the input signals, in particular the Emergency Stop (STOP) and Drive Prohibit (POT/NOT) inputs are
settled before the protective function starts working.
