(2) Power Supply Sequence
The diagram below shows the timing of power ON/OFF of the drive unit 200VAC (400VAC), the optical
communication repeater unit, and the control unit.
[Power ON]
Turn the power ON in the following order; drive unit -> optical communication repeater unit -> control unit
If the control unit is powered ON before the optical communication repeater unit, the initial communication with the
drive unit may fail and cause an alarm.
[Power OFF]
Turn the power OFF in the following order; control unit -> optical communication repeater unit -> drive unit.
Set aside more than 8ms the time difference between the power OFF of the control unit and the power OFF of the
optical communication repeater unit.
If the optical communication repeater unit is powered OFF before the drive unit, or the time lag is less than 8ms,
data acquisition from the drive unit may fail and cause an alarm.
t1: Time lag between the power-ON of the drive unit and the optical communication repeater unit
t2: Time lag between the power-ON of the optical communication repeater unit and the control unit
t3: Time lag between the power-OFF of the optical communication repeater unit and the control unit
