(Note) After connecting the power, it takes about 1-2 seconds until the alarm signal leads
to normal operation. Consider this when designing the power connection sequence.
Also the alarm signal operates alarm detection relay 1Ry to turn on the main circuit
power of servo drive.
It only has the signals related to Mitsubishi AD72 and FDA7000 Series
(Note) The above connection is only shown in case of P07-01=26 (Speed control mode).
