• This signal transmission method has better noise immunity.
We recommend this to secure the signal transmission when line driver I/F is used.
• 1 system: PI2. For function, refer to P.3-38, P.3-39.

• It goes through 3 systems, AI1 to AI3.
• Max. permissible input voltage to each input is ±10 V.
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
–10 V to +10 V, use VR with 2 kΩ, B-characteristics, 1/2 W or larger, R with 200 Ω, 1/2 W or
larger.
• A/D converter resolution of each command input is as follows.
(1)ADC1 : 16-bit (AI1)
(2)ADC2 : 12-bit (AI2, AI3)
• For function, refer to P.3-46, P.3-47.
