The emergency object is always size 8 bytes:Assignment of user data: Error0(LB)/Error1(HB): 16-bit error code Error-Reg: Error register (contents of object 0x1001, see chap. 6.1, p. 43) FE0(LB)/FE1(HB): 16-bit FAULHABER error register (contents of object 0x2320, seeTab. 12) Bytes 5 to 7: unused (0)The error register identifies the error type. The individual error types are bit-coded and areassigned to the respective error codes. The object 0x1001 allows interrogation of the lastvalue of the error register.Tab. 9 lists all the errors that have been reported by emergency messages, providing therespective error is included in the emergency mask for the FAULHABER error register(Tab. 13).Tab. 9: Emergency error codes11-bit identi-fier8 bytes user data0x80 (128d) +node IDError0(LB) Error1(HB) Error-Reg FE0 (LB) FE1 (HB) 0 0 0Emergency message FAULHABER error register 0x2320 Error register 0x1001ErrorCodeDesignation Errormask0x2321Bit Designation Bit Designation0x0000 No error (is sent outwhen an error is nolonger present or hasbeen acknowledged)– – – – –– – – – 0 Generic error(is set if one of the error bits 1to 7 is set)0x3210 Overvoltage 0x0004 2 OverVoltageError 2 Voltage error0x3220 Undervoltage 0x0008 3 UnderVoltageError 2 Voltage error0x43F0 Temperature warning 0x0010 4 TempWarning 1 Current errora)0x4310 Temperature Error 0x0020 5 TempError 3 Temperature error0x5410 Output stages 0x0080 7 IntHW error 7 Manufacturer-specific error0x5530 EEPROM fault 0x0400 10 Memory error – –0x6100 Software error 0x1000 12 Calculation error 7 Manufacturer-specific error
