This section provides troubleshooting flowcharts when Servo Drive communi-
cations cannot be established or movement is not possible even when move-
ment commands are sent from the ladder program.
12-5-1 Initial Troubleshooting
The following troubleshooting flowchart is for errors that occur during initial
checking.
This flowchart can be used to determine whether the PCU is faulty and cannot

The Servo Drive cannot communicate.
The Servomotor will not operate in
response to commands.
Is the RUN indicator lit?
Are any other
indicators lit?
Is the ERH indicator lit?
Is power being supplied to
the PLC correctly?
Is the unit number
set correctly?
Are the I/O tables
set correctly?
Supply the correct
power supply
voltage to the PLC.
Make sure that the PCU
is installed correctly,
and turn the power OFF
and ON again.
If the problem occurs
again, the probable
cause is a faulty PCU
Unit. Replace the PCU.
Create the I/O
tables for the CPU
Unit again.
Check whether the
PCU's unit number is
the same as another
Unit.
