10.2 Cable Size
 Main circuit section
600 V class 2 vinyl cable, or 600 V polyethylene insulated cable (HIV cable)
When compared with the IV cable, the cable size is smaller and the cable is superior in
flexibility and the maximum allowable temperature as an insulated cable is as high as 75°C.
Therefore this cable is used both for the main circuit and for the control circuit.
However, if the cable is used for the control circuit, the wiring distance must be short and the
cable must be twisted.
600 V cross linked polyethylene insulated cable (CV cable)
Mainly used for the main circuit and grounding circuit. When compared with the IV and HIV
cables, the cable size is smaller and the cable is superior in flexibility. Due to these features,
the cable is used for higher ambient temperatures (50°C, etc.), reduced cable space,
improved actuation efficiency, etc. The maximum allowable temperature as an insulated cable
is 90°C.
[Example]:BOARDLEX made by FURUKAWA ELECTRIC
 Control circuit section
Twisted shielded cable for electronic and electric devices
Used for control circuits. Use this cable for applications susceptible to (potential) radiant noise
and inductive noise. The cable has a large shielding effect. Even inside panels, use this cable
without fail if the wiring distance is long.
[Example]: BEAMEX S shielded cable XEBV or XEWV made by FURUKAWA ELECTRIC
Encoder section
The encoder cable of the servomotor is a composite 2C (cable), 2P (pair) shielded cable
housing different cable sizes shown below.
Cross linked polyethylene vinyl sheath cable for robot travel (composite cable) (DAIDEN Co., Ltd.)
RMCV-SB-A (UL2464) AWG#25/2P+AWG#23/2C (wiring length ≤ 10 m)
RMCV-SB-A (UL2464) AWG#25/2P+AWG#17/2C (10 m < wiring length ≤ 50 m)
