NOTE
1 In Fig. 5.2 (c), the 24–VDC power source must have a
startup time not exceeding 500 ms.
2 In Figs. 5.2 (a) to 5.2 (c), the FANUC I/O Link slave (such as
an I/O card) is a slave of the Power Mate i.
3 In Figs. 5.2 (b) and 5.2 (c), the FANUC I/O Link master (such
as a CNC) acts as the master for the Power Mate i.
The power to separate detectors (scales) can be supplied from the
separate detector interface unit, provided that the current (voltage) is
0.35 A (5 V) or less per scale. Note that the separate detector (scale)
to which the power is to be supplied from the separate detector
interface unit must be such that the A/B–phase signal is stabilized
within 500 ms of the power being turned on.
