The MPG's ratio (factor) is too great, so the command value
cannot occur. Reduce the MPG ratio or the frequency of the
pulses from the MPG. (Turn the MPG a little slower.)
The feedback pulses exceeded 625,000 pps or a task error
occurred while the absolute encoder's data was being read
and the read was cancelled.
The encoder dividing ratio set in the Servo Driver parameters
is wrong.
When using the U Series, check the setting of Cn-0A.
When using the W Series, check the setting of Pn201.
When using the G Series, check the setting of Pn44 and set
Pn45 to 0.
The excessive feedback pulse frequency could be caused by
a broken encoder cable, encoder error, or noise.
Take appropriate countermeasures and try again.
Remove the causes that have caused the task error.
Important errors detected at the MC Unit are saved in non-volatile memory.
These records can be accessed during maintenance and inspection to see
what kinds of errors have been occurring, and how often. The error log can be
read using the CX-Motion.
The following table shows the kinds of errors that are saved in the error log.
Error
Error processing
Processing
Follow the instructions in the applicable PLC manual.
May be caused by the following:
An end refresh prohibition is set by the CPU Unit.
The CPU Unit scan time is too short.
Take the following countermeasures:
Clear the end refresh prohibition.
Lengthen the CPU Unit scan time.
Make adjustments at the CPU Unit.
Check whether the MC Unit is securely mounted to the
Backplane. If the error persists, the CPU Unit or the
Backplane may be defective. Replace the CPU Unit or the
Backplane.
May be caused by the following:
The unit number is not correctly set.
The unit number is allocated to another
Special I/O Unit.
Set the unit number correctly and power up again.
Follow the instructions in the applicable PLC manual.
Follow the instructions in the applicable PLC manual.
These errors do not normally occur. If they do occur,
contact an OMRON representative.
An error has occurred at the flash memory or EEPROM. If
this error occurs frequently, replace the MC Unit.
Refer to the system error code 0001 hex.
Refer to the system error code 0003 hex.
