Tag not present error
(ERR_72)
This bit is set if a communicable ID
tag is not present within the antenna
communication area.
(1) Check the distance between the antenna
and ID tag and secure the communication
distance.
(2) Decrease the axis deflection between the
antenna and ID tag.
(3) Measure the surrounding noise of the
antenna. If excessive noise is occurring,
remove the noise source. (Refer to Section
5.1.3 (4) "Noise level measurement".)
(4) Check if the antenna is connected correctly.
(5) Check the types of the antenna and the
amplifier connected to the module, and the ID
tag to find out whether they are supported.
(6) If the error occurs even though the antenna,
amplifier and ID tag are applicable, failure
most likely occurred. Replace the part.
11
Protect error
(ERR_7D)
This bit is set if data is written to an
area that is write protected.
(1) Properly set the start address specification
and number of processing points specification
written to the ID tag.
(2) Properly set the start address and end
address of the write protect setting area.
(3) Set the write protect enable/disable setting to
disable, thereby cancelling write protect.
12
Tag communication
error
(ERR_70)
This bit is set if communication with
an ID tag does not end normally.
(1) Make sure that there is one ID tag within the
antenna communication area.
(2) Measure the surrounding noise of the
antenna. If excessive noise is occurring,
remove the noise source. (Refer to Section
5.1.3 (4) "Noise level measurement".)
(3) Slow down the movement speed of the ID tag.
(4) Check the distance between the antenna
and ID tag and secure the communication
distance.
(5) If you are using two or more antennas,
increase the distance between the antennas.
(6) Check the types of the antenna and the
amplifier connected to the module, and the ID
tag to find out whether they are supported.
(7) If the error occurs even though the antenna,
amplifier and ID tag are applicable, failure
most likely occurred. Replace the part.
13
Address error
(ERR_7A)
This bit is set if an attempt is made to
read or write beyond the ID tag
address specifiable range.
(1) Properly set the start address specification and
number of processing points specification of ID
tag memory.
