4. Inputs and outputs on connector X4
Interface Circuit (Input)
Connection to sequence input signals
PI2
(Pulse train interface exclusive to line driver)
Line driver I/F (Input pulse frequency : max. 4Mpps)
• This signal transmission method has better noise immunity.
We recommend this to secure the signal transmission when line driver I/F is used.

Analog command input
• The analog command input goes through 3 routes, SPR (Pin-14), P-ATL (Pin-16) and N-ATL
(Pin-18).
• Max. permissible input voltage to each input is ±10V.
For input impedance of each input, refer to the right Fig.
• When you compose a simple command circuit using variable resistor(VR) and register R,
connect as the right Fig. shows. When the variable range of each input is made as
–10V to +10V, use VR with 2kW, B-characteristics, 1/2W or larger, R with 200W, 1/2W or
larger.
• A/D converter resolution of each command input is as follows.
(1)ADC1 : 16 bit (SPR/TRQR)
(2)ADC2 : 12 bit (P-ATL and N-ATL)
