If you encountered an error which is not explained below, use CX-Programmer to print out the
details of the problem, allocated areas and parameters and send the information to OMRON.
If your system operates unexpectedly, the transferred parameters and memory operation data
may not be saved in the flash memory. Check if the parameters and data are saved in the flash
memory.
If your system operates unexpectedly, data or flags may not be exchanged properly between
the ladder program and PCU.
Use the data tracing function of CX-Programmer to check if data and flags are exchanged at
the correct timings.
The RUN
LED of the
CPU Unit
does not turn
ON after you
turn ON the
power
supply.
Only the RUN
LED of the
PCU does not
turn ON after
you turn ON
the power
supply.
Motor does
not lock.
Problem
Wrong wiring of the
power supply line
Drop in power supply
voltage
Faulty power supply
Insufficient power
supply capacity
Failure
The PCU does not
output operation
commands to the
Servo Drive.
Drive setting error
Probable cause
Check the wiring of the
power supply.
Check the voltage of the
power supply.
Add up the power supply
capacities of the CPU
Units which are installed
in the same system, as
well as all other units,
and compare the total
power supply capacity
against the power
supply capacity of the
Power Supply Unit. If the
total power supply
capacity exceeds the
capacity of the Power
supply Unit, you cannot
use your system
properly.
Check the wiring of the
RUN output signal
between the PCU and
driver.
Check if the ladder
program is executing
servo lock.
Check the drive
settings.
Item to check
−
−
Wire correctly.
Use the correct power
supply.
Check the power supply
capacity.
Replace the power
supply.
Increase the power
supply capacity.
Change the system
configuration so that the
power supply capacity is
not exceeded.
Perform the actions from
"LED Error Indicator" on
page 12-11 onward.
Change the wiring.
Correct the ladder
program.
Set the drive correctly.
