6. CONNECTION OF I/O UNITS TO
MACHINE INTERFACE
B–63173EN/03
120
Recommended connector:
A02B–0120–K303 (such as the following connector and its
housing)
(Connector:Soldering–type FI40–2015S, manufactured by Hirose
Electric Co., Ltd.)
(Housing:FI–20–CV, manufactured by Hirose Electric Co., Ltd.)
Recommended cables:
A02B–0120–K841 (7 m) (for connecting three manual pulse
generators)
A02B–0120–K848 (7 m) (for connecting two manual pulse
generators)
A02B–0120–K847 (7 m) (for connecting one manual pulse
generator)
(These cables do not include the wire shown in the above figure.)
NOTE
1 The Power Mate i–D supports the connection of only two
manual pulse generators. In such cases, signals HA3 and
HB3 are not used.
2 The interface cannot be used together with the manual
pulse generator interface of the Power Mate i.
Like a pulse coder, the manual pulse generator operates on 5 VDC. The
supply voltage drop due to the cable resistance must be held below 0.2 V
(when those of the 0–volt and 5–volt wires are combined), as expressed
in the following expression:
Where
0.1 = manual pulse generator supply
current (0.1 A)
R = resistance per unit cable length
(W/m)
m = number of 0–volt and 5–volt wires
L = cable length (m).
Therefore, the cable length can be determined using the following
expression.
In the case of the A66L–0001–0286 cable, for example, when three pairs
of signal wires and six power supply wires (20/0.18, 0.0394 W/m) are
used (three power supply wires connected to 5 V and the other three to 0
V when one manual pulse generator is used), the cable length is:
However, the maximum pulse transmission distance for the manual pulse
generator is 50 m. Taking this into consideration, the cable length may
be extended to:
38.37 m (when two manual pulse generators are used), or
25.58 m (when three manual pulse generators are used).
