Error name
Description
ID System error 1
ID System error
Tag not present
No communicable RF tag are in the
error
antenna communication area.
Tag communication
Communication with the RF tag is not
error
completed successfully.
Address error
Read/Write data exceed the address
range of RF tag.
Antenna error
The following causes are conceivable.
• The antenna or amplifier is not
connected.
• An unavailable antenna is connected.
• The antenna breaks.
Action
Please consult your local Mitsubishi
representative and explain the error details.
• Check the distance between the antenna and
RF tag, and set them within the communication
range.
• Keep the less axis gap between the antenna
and RF tag.
• Measure the ambient noise. If excessive noise
is generated, eliminate the noise source. (
Page 85 Noise level)
• Check that the antenna is connected correctly.
• 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.
• Place only one RF tag within the antenna
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
are available for the module. Even so, if an error
occurs, the devices may break.
Set the correct value to the No. of processing
points specification area (Un\G4, Un\G4004) of
the RF tag.
• Check that the amplifier and antenna are
connected correctly.
• Check that the antenna and amplifier connected
to the module are available for the module.
Even so, if an error occurs, the devices may
break.
