When Cannot Write To Motion Cpu; When Cannot Read From Motion Cpu; When The Servo Amplifier Does Not Start - Mitsubishi Electric R64MTCPU User Manual

If an error is still displayed or flickers in the dot matrix LED after checking the above items, there may be a hardware error.
Please consult your local Mitsubishi representative.

When cannot write to Motion CPU

When cannot write to Motion CPU, check the following items.
Check item
Has a password been registered?
With the SD memory card as the write target, is the SD memory card write-
protected?
With the SD memory card as the write target, has the SD memory card not
been formatted?
Does the writing data exceed the capacity of the standard ROM or the SD
memory card?
With the Multiple CPU system in an erroneous state (self-diagnostic errors
such as CPU configuration error, parameter error etc. occurring), is
transmission via Multiple CPU being performed?
If write to Motion CPU cannot be performed after checking the above items, there may be a hardware error. Please consult
your local Mitsubishi representative.

When cannot read from Motion CPU

When cannot read from Motion CPU, check the following items.
Check item
Has a password been registered?
Is the specified target memory for reading incorrect?
With the Multiple CPU system in an erroneous state (self-diagnostic errors
such as CPU configuration error, parameter error etc. occurring), is
transmission via Multiple CPU being performed?
If read from Motion CPU cannot be performed after checking the above items, there may be a hardware error. Please consult
your local Mitsubishi representative.

When the servo amplifier does not start

When the servo amplifier does not start, check the following items.
Check item
An error is displayed or flickering in the dot matrix LED of the Motion CPU.
Is the SSCNET cable connected correctly?
Have the applicable axes been set in the parameters?
Have the setting switches on the servo amplifier been set correctly?
Are the servo amplifiers connected closer to the Motion controller than the
applicable axis started?
If the servo amplifier does not start after checking the above items, there may be a hardware error. Please consult your local
Mitsubishi representative.
Corrective action
Authenticate a password in MT Developer2.
Remove the write-protect from the SD memory card.
Format the SD memory card.
Secure enough free-space on the standard ROM or the SD memory card.
Use the PERIPHERAL I/F of the Motion CPU to write to the Motion CPU.
Corrective action
Authenticate a password in MT Developer2.
Check the target memory (standard ROM, SD memory card) for reading is
correct.
Use the PERIPHERAL I/F of the Motion CPU to read from the Motion CPU.
Corrective action
Check the display of dot matrix LED, and remove the error factor.
(Page 66 When an error is displayed or flickering in the dot matrix LED)
Connect the SSCNET cable correctly.
Set the applicable axes in [Motion CPU Common Parameter]  [Servo Network
Setting] of MT Developer2.
Set the axis select rotary switch and auxiliary axis No. setting switch correctly.
Check the error on the servo amplifier that is not starting, and remove the error
factor.
