◆ Broadcast Messages
Data can be written from the master to all slave devices at the same time.
The slave address in a broadcast command message must be set to 00H. All slaves will receive the message, but will not
respond.
◆ Fault Trace Contents
The table below shows the fault codes that can be read out by MEMOBUS/Modbus commands from the U2-†† monitor
parameters.

<1> Parameter o1-03, Digital Operator Display Selection, determines the units.
<2> The display resolution depends on the rated output power of the drive. Models 2A0018 to 2A0041 and 4A0009 to 4A0023 display values in
0.01 A units, while models 2A0059 to 2A0432 and 4A0030 to 4A0260 display values in 0.1 A units.
<3> Communication error contents are saved until the fault is reset.
<4> Set the number of motor poles to parameter E2-04, E4-04, or E5-05 depending on the motor being used.
