FANUC Power Mate i-MODEL H CONNECTION MANUAL (HARDWARE)

B63173EN/03
10. CONNECTION TO PERIPHERALS
389
NOTE
1 To use this function, option card 1 or 2 is needed.
2 This interface cannot be used together with an position
coder interface.
3 The Power Mate can supply power to a unit requiring not
more than 0.35 A at 5 V (the total for two external pulse
generators if used). In this case, pay careful attention to the
voltage drop caused by the cable resistance. Assume 4.95
V for the 5 V power of the Power Mate.
4 Line length is 50m or less.
5 Do not make any connection other than the above.
(a) Operating conditions
The maximum allowable frequency for the input signal is 100 kHz (the
frequency is, however, multiplied by four in the CNC).
