---Manual pulse generator I/F specification----
Input pulse signal type: 90°phase difference between HA1 and HB1.
Max. input pulse frequency : 100kHz
Number of pulses per rotation: 100pulse/rev
Input signal voltage : H level 3.5V to 5.25V, L level 0V to 0.5V
Output power voltage : +5VDC -10% -10%
Max. output current : 100mA
(Note) The connector MPG and EXT I/F have input pins for HA1 and
HB1. Use either of the connectors.
HA1 (HB1)
HB1 (HA1)
a
a.b.c.d.e: HA1 or HB1 rising edge (falling edge) phase difference = T/4 ± T/10
T: HA1 or HB1 cycle (Min. 10μs)
---SKIP I/F specification---
Input ON voltage : 18V or more to 25.2V or
less
Input ON current : 6mA or more
Input OFF voltage : 4V or less
Input OFF current : 2mA or less
Input signal holding time (Ton) : 2ms or
more
Internal response time :0.08ms or less
(Note) NC recognizes input signals of 2ms or more as the valid skip signals. If
machine contacts (relay, etc.) are used, malfunctions will occur due to chatter-
ing. Use semiconductor contacts (transistor, etc.).
