7.3 Connecting the I/O signals
Connect the I/O signals to the I/O signal connector (CN4). Keep the wiring distance as short as possible [less than 2 m
(6.6 ft.)] to suppress the eect of noise.
Note
•
The connector for connecting the I/O signals is not included. Provide the following products.
· D-Sub connector (15-pin)
· Hood (screw: No.4-40UNC)
•
Wire the I/O signal cable at a distance of 100 mm (3.94 in) or more apart from the inductive load
(electromagnetic relay etc.), power supply or power cable (motor cable etc.).

Output signals circuit
All output signals of the driver are photocoupler/open-collector outputs.
The ON voltage of the output circuit is maximum 1.5 V (0.5 V for SPEED-OUT
output). When driving each element using the output signal circuit, give
consideration to this ON voltage.

: 30 VDC or less and 100 mA or less
BLV640
: 53 VDC or less and 100 mA or less
(The current of the SPEED-OUT output should be maximum 10 mA)

Note
•
Always connect a current-limiting resistor. If the power supply voltage is connected to the output circuit
directly without connecting a current-limiting resistor in between, the driver will be damaged.
•
When connecting a relay (inductive load), etc., to detect alarm outputs,
provide a y-back voltage control measure based on diode, etc., for the
inductive load. Or use a relay with built-in ywheel diode.
