Input Circuit
Wiring to the Connector, CN X5
(1) Line driver I/F (Input pulse frequency : max. 500kpps)
• This signal transmission method has better noise immunity.
We recommend this to secure the signal transmission.
(2)Open collector I/F (Input pulse frequency : max. 200kpps)
• The method which uses an external control signal power supply (V
DC
)
• Current regulating resistor R corresponding to V
DC
is
required in this case.
• Connect the specified resister as below.
(3)Open collector I/F (Input pulse frequency : max. 200kpps)
• Connecting diagram when a current regulating resistor is not
used with 24V power supply.

• Connect to contacts of switches and relays, or open collector output transistors.
• When you use contact inputs, use the switches and relays for micro current to avoid contact failure.
• Make the lower limit voltage of the power supply (12 to 24V) as 11.4V or more in order to secure the primary
current for photo-couplers.

Analog command input
AI
• The analog command input goes through 3 routes,
SPR/TRQR(Pin-14), CCWTL (Pin-16) and CWTL (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 2k
Ω
, B-characteristics, 1/2W or larger, R
with 200
Ω
, 1/2W or larger.
• A/D converter resolution of each command input is as follows.
(1)ADC1 : 16 bit (SPR/TRQR), (including 1bit for sign),
±
10V
(2)ADC2 : 10 bit (CCWTL, CWTL), 0 to 3.3V
