Status Register The object 1001H (Error Register) is a byte used by the device to display internal

(EMCY Byte 2) errors when an error is detected:

Bit	Description	Comments
0	Generic error	See Object 1003H
1	Current fault (overload or short-circuit)	See Object 1003H
2	Voltage fault	See Object 1003H
3	Temperature	Unchecked
4	Communication error	See Object 1003H
5	Reserved	Unchecked
6	Reserved	Unchecked
7	Specific to the manufacturer	Detection of wire cut on sensor

Channel	Data returned in bytes 5 and 6 is the image of channels with the error defined by
Diagnostics	EMCY byte 7 (manufacturer status register):
(EMCY Bytes 5-6-
	Byte	6 (channels 0 to 7)	5 (channels 10 to	7
7)
			17)
	Contents	Faulty channels	Faulty channels	Types of faults

The following table indicates the assignment of all EMCY byte 7 bits:
