SECTION 2
Installation and Connections/Wiring
■ Influence of Background Metal on ID Tag
Metals in the vicinity of the communications area will affect the range, making it smaller.
Refer to page 110.
■ Influence of Noise
This CIDRW system uses a frequency of 134 kHz for communications with ID Tags. Equipment such
as switching power supplies, inverters, servomotors, or monitors in the surrounding area will adversely
affect communications, restricting the communications area.
The noise levels in the vicinity of the CIDRW Head can be determined with the environmental NOISE MEASUREMENT
command (applies only when SECS is not used)
For details on the relationship between noise and communications distance, see Appendix
■ Mounting
Use spring washers and flat washers with the four M3 screws when mounting a CIDRW Head.
Mounting dimensions
4-M3 OR 3.5 dia.
4-M3 OR 3.5 dia.
*The mounting dimensions are same between V640-HS61 and V640-HS62.
