of controller.

of sending packets from the
controller.
Checking Method
The computing time in IP mode
takes too long. Please disable the
USB monitoring function.
Checking Method
Examine the content of 0x1006.If
it is smaller than or equals to 0, the
alarm will occur.
Checking Method
Check if the DI (0x47) is accidently
triggered because of the parameter
setting.
Checking Method
Please refer to the description of
parameter P1-48.
After DO.MC_OK has been ON,
DO.MC_OK becomes OFF because
