10-1) Cable size
The electric circuits inside the control panel can be divided into the main circuit and control circuit.
Cables used for general circuits except for those of encoder wiring of the servomotor are as follows.
n 600V class, poly-vinyl insulated cable (JIS C 3307: IV)
Used for main circuit. The cable cannot be twisted.
n Poly-vinyl insulated cable for electric appliances (JIS C 3316: KIV)
Can be used for all circuits; superior in flexibility.
n 600V class, cross-link polyethylene insulated cable (JCS 360 (standard of the Japanese
Electric Wire & Cable Maker’s Association): FSCL)
Used for main circuit. The cable size is smaller than the 600V-class poly-vinyl cable and superior in
flexibility.
Example: Furukawa Electric’s Baudrex
n Twisted shielded cable for electronic devices and electric appliances
Used for control circuit. Cables are prone to radio noise and inductive noise even in the panel and
therefore shielded cables should be used.
Example: Furukawa Electric’s Beemex S Shielded Cable XEBV or XEWV
The encoder cable for the servomotor is a composite 2C (cable) 4P (pair) shielded cable housing
cables of different sizes.
n Cross-link polyethylene poly-vinyl insulated cable for robot travel (twisted pair type) (Daito
Co., Ltd.)
RMCV-SV AWG#25 / 4P + AWG#23 / 2C (within 10m)
AWG#25 / 4P + AWG#17 / 2C (within 50m)
