9. CONNECTION TO SERVO OR SPINDLE
When a separate pulse coder or linear scale is used, a separate detector
interface unit is required. The separate detector interface unit should be
connected to the Power Mate control unit through an optical cable, as one
of the units on the servo interface (FSSB). See Figures in Sec. 9.1. The
separate detector interface connected in the final stage of the FSSB line,
it can also be connected, at the nearest location, to the Power Mate control
unit. Or, it can be installed between two servo amplifier modules.
Usually, the separate detectors corresponding to the servo motors for the
first to eighth axes are connected to JF101 to JF108 of the separate
detector interface. If required, the controlled axis numbers corresponding
to JF101 to JF108 may be changed. For example, in the figure above, if
separate detectors are used for the second, fourth, sixth, and eighth
controlled axes only, the second, fourth, sixth, and eighth axes can be
made to correspond to JF101 to JF104 of the basic unit, eliminating the
need for an additional unit. The power that the unit can supply to separate
detectors is 0.35 A (5V) per detector.
1 When the separate detector interface unit is used with the
serial interface in the Power Mate i, a high–speed axis
control card is required.
2 The +5–V output in the interface can be used as the power
supply of a separate detector or linear scale. The supply
current per separate detector is 0.35 A maximum. The
voltage of the basic unit is 4.95 V (min), and that of the
additional unit is 4.90 V (min).
