4.1.3 Prevention of noise
Separate the communications cable from drive power cables and other communications cables more than
50cm so as not to be affected by noises.
4.1.4 Crimp style terminals
Falling off of connections is one of communications
failures. Terminate the communications cable with an
[O] or [Y] type crimp style terminal having an
insulation sleeve. (The terminal screws of SE3000
series field scanner and line converters are
M3.5mm.)
4.1.5 Mount an insulation resistor
For using the RS-422A or RS-485 communications interface, mount a 100
Ω
resistor to the SE3000
scanner connected at the final end. (For details, see Section 4.4)
[A general metal film resistor can be used. The resistor (sold separately) is available at CHINO.]
4.1.6 Number of SE3000 series field scanner connectable
For RS-232C:
1 set
For RS-422A or RS-485: Up to 31 sets
