Recommended cables:
A02B0259K822 (7m) (for connecting two manual pulse
generators)
A02B0259K821 (7m) (for connecting one manual pulse
generator)
(These cables are those used between the JA47 connector and the
connector panel.)
Do not make any connection other than the above.
NOTE
Do not make any connection other than the above.
Like a pulse coder, the manual pulse generator (manufactured byFANUC)
operates on 5 VDC. The supply voltage drop due to the cable resistance
must be held below 0.2 V (when those of the 0volt and 5volt wires are
combined), as expressed in the following expression:
Wher
0.1 = manual pulse generator supply
current (0.1 A)/unit
R = resistance per unit cable length
(W/m)
m = number of 0volt and 5volt wires
L = cable length (m).
Therefore, the cable length can be determined using the following
expression.
In the case of the A66L00010286 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).
