Apply the following power–on sequence. Alternatively, turn on the
power to all the units simultaneously.
1 Power to the entire machine <200 VAC>
Power to the servo amplifier <200 VAC>
Power to the separate detector
2 Power to the separate detector interface unit <24 VDC>
3 Power to the Digital Servo Adapter <24 VDC>
“Simultaneously,” as used here, refers to the following:
The units described in items 1 and 2 are turned on within 500 ms of the
Digital Servo Adapter in item 3 being turned on.

If a separate detector (scale) of parallel interface is used and its power is
supplied from a power source other than a separate detector interface unit,
turn on the power to the separate detector (scale) before turning on the
power to the separate detector interface unit. The A/B–phase signal of the
separate detector (scale) must be stabilized before the separate detector
interface unit is turned on.
