10. CONNECTION TO PERIPHERALS
In the Power Mate i–H, an external pulse generator with a single–phase
input can be connected instead of the manual pulse generator
manufactured by FANUC.
The relationship between the HAn and HBn signals and the Power Mate
pulses shall be as shown in Fig. 10.3.4 (a).
Pulse cycle T
shall be 200 msec or more. Pulse cycle T
/4 shall be 50 msec
Fig. 10.3.4 (a)
A circuit configuration shown in Fig. 10.3.4 (b) is recommended for the
output signals of the external pulse generator.

Input signal level change point (threshold)
When the voltage is 3.7 V or higher, the input signal level changes
from low to high.
When the voltage is 1.5 V or lower, the input signal level changes from
high to low.
