8.1.5.2 Object 0x2834: Fault retain status
All reported faults in bit coded form since powering on the servo valve.
8.1.6 Error register
The <ErrorRegister> (0x1001) displays the error information about the last reported fault in bit-coded form.
Bit 0 of the <ErrorRegister> (0x1001) is set as soon as an error occurs on the servo valve.
8.1.6.1 Object 0x1001: Error register
This object shall provide error information. The CANopen device maps internal errors into this object. This in-
formation is also sent with the emergency object.
Value description
If a specific error occurs, the corresponding bit shall be set to 1
b
. The bits are cleared automatically when the
error has gone.
