Description
Stores the cumulative error occurrence count of the forward loop (IN-side) communication
short frame error.
0: No error
1 or greater: Cumulative count
There is no problem if values are counted up little by little over a long period of time. If
values are rapidly counted up in a short period of time, check if the cables are faulty.
Stores the cumulative error occurrence count of the forward loop (IN-side) communication
abort error.
0: No error
1 or greater: Cumulative count
There is no problem if values are counted up little by little over a long period of time. If
values are rapidly counted up in a short period of time, check if the cables are faulty.
Stores the cumulative error occurrence count of the forward loop (IN-side) communication
timeout.
0: No error
1 or greater: Cumulative count
There is no problem if values are counted up little by little over a long period of time. If
values are rapidly counted up in a short period of time, check if the cables are faulty.
Stores the cumulative error occurrence count of the reception of 2K bytes or more at the
forward loop (IN-side).
0: No error
1 or greater: Cumulative count
There is no problem if values are counted up little by little over a long period of time. If
values are rapidly counted up in a short period of time, check if the cables are faulty.
Stores the cumulative error occurrence count of the forward loop (IN-side) communication
DPLL error.
0: No error
1 or greater: Cumulative count
There is no problem if values are counted up little by little over a long period of time. If
values are rapidly counted up in a short period of time, check if the cables are faulty.
Stores the cumulative error occurrence count of the reverse loop (OUT-side)
communication under-error.
0: No error
1 or greater: Cumulative count
There is no problem if values are counted up little by little over a long period of time. If
values are rapidly counted up in a short period of time, check if the cables are faulty.
Stores the cumulative error occurrence count of the reverse loop (OUT-side)
communication CRC error.
0: No error
1 or greater: Cumulative count
There is no problem if values are counted up little by little over a long period of time. If
values are rapidly counted up in a short period of time, check if the cables are faulty.
Stores the cumulative error occurrence count of the reverse loop (OUT-side)
communication overrun error.
0: No error
1 or greater: Cumulative count
There is no problem if values are counted up little by little over a long period of time. If
values are rapidly counted up in a short period of time, check if the cables are faulty.
Stores the cumulative error occurrence count of the reverse loop (OUT-side)
communication short frame error.
0: No error
1 or greater: Cumulative count
There is no problem if values are counted up little by little over a long period of time. If
values are rapidly counted up in a short period of time, check if the cables are faulty.
Stores the cumulative error occurrence count of the reverse loop (OUT-side)
communication abort error.
0: No error
1 or greater: Cumulative count
There is no problem if values are counted up little by little over a long period of time. If
values are rapidly counted up in a short period of time, check if the cables are faulty.
