6.2 Performance Data Based on Operating Conditions
(information only)
The maximum effective communication distance of an IDRW head varies depending on the operating
conditions (presence/absence of a nearby metal object, spacing between the IDRW heads, etc.). This section
describes the effect of varying operating conditions on the effective communication distance. Before operating
the IDRW heads, study the information in this section. The values mentioned here are given only as a
guideline.
6.2.1 Effect of nearby metal object onto IDRW head
■ Model V700-HMD13
When mounting the Model V700-HMD13 , make sure that the communication surface of IDRW head
is not below the top surface of sheet metal top panel (mounting bracket). Otherwise, the effective com-
munication distance will decrease.
■ Model V700-HMD11-1
A metal object located in the vicinity of the Model V700-HMD11-1 decreases the effective communica-
tion distance of the IDRW head. The correlation between the distance between iron object and IDRW
head and the effective communication distance (read/write, misalignment of ±0 mm) is plotted below.
