*2 (ERR_) means the system error code of the Omron RFID system.
*3 When an error occurs at the Copy command on the copy destination side, the bit of the copy source side turns on.
*4 When an error occurs as a result of data writing after reading at the Copy command, the status flag (bit 4) turns on.

Error name Description
Protect error Data are written in a protected area.
(ERR_7D)
Tag communication Communication with the RF tag is not
error completed successfully.
(ERR_70)
Address error Read/Write data exceed the address
(ERR_7A) range of RF tag.
Verify error Data are not written to the RF tag
*4
ASCII/HEX normally.
conversion error
(ERR_71)
When data are read with ASCII/HEX
conversion, the RF tag includes data that
cannot be converted.
Antenna error The following causes are conceivable.
(ERR_7C) • The antenna or amplifier is not
connected.
• An unavailable antenna is connected.
• The antenna breaks.
Action

• Correct the head address and the number of
processing points to write to the RF tag.
• Correct the start address and end address of
the write protect setting area.
• Set "Disable" to "Write protect enable/disable
setting" to clear the write protect setting.
• Place only one RF tag within the antenna
*4
communication range.
• Measure the ambient noise. If excessive noise
is generated, eliminate the noise source. (
Page 85 Noise level)
• Slow down the movement speed of the RF tag.
• Check the distance between the antenna and
RF tag, and set them within the communication
range.
• When using two antennas or more, keep
suitable distance between antennas.
• Check that the antenna, amplifier, and RF tag
connected to the module are available for the
module. Even so, if an error occurs, the devices
may break.
Set the correct value to the head address and No.
of processing points specification area (Un\G4,
Un\G4004) of the RF tag memory.
• Slow down the movement speed of the RF tag.
• Measure the ambient noise. If excessive noise
is generated, eliminate the noise source. (
Page 85 Noise level)
Specify the data that consists of only "0" to "9" and
"A" to "F".
• Check that the antenna and amplifier are
connected correctly.
• Check that the antenna and amplifier are
available for the module. Even so, if an error
occurs, the devices may break.
