20. EMC AND LOW VOLTAGE DIRECTIVES
(c) Always use double-shielded coaxial cables as the coaxial cables
*2
connected to
the 10BASE2 connectors. Ground the double-shielded coaxial cable by
connecting its outer shield to the ground.
Refer to (1) for the grounding of the shield.
*2 Make sure to attach a ferrite core to the cable.
As a ferrite core, ZCAT2035 manufactured by TDK is recommended.
(4) I/O signal cables and other communication cables
Always ground the I/O signal lines (including common line) and other communication
cables (RS-232-C, RS-422, etc.) in the same manner as described in (1) if they are
brought out of the control panel.
(5) Positioning modules
Precautions for configuring machinery compliant with the EMC Directives using the
AD75P -S3 are described below.
(a) When using a cable of 2m (6.56ft.) or less
• Ground the shield section of the external wiring cable with a cable clamp.
(Ground the shield at the closest location to the AD75 external wiring
connector.)
• Connect the external wiring cable to a drive unit or an external device in the
shortest distance.
• Install the drive unit in the same panel.
