Information
1000 0 Device Type Unsigned32 RO Describes the type of the device. Composed of two 16-bit fields (one for
device profile, the other for additional information. The object value of
the NCAN-02 is 0×0192, which corresponds to drive profile DSP-402
(0×192), and to additional information
Frequency Converter (0×01).
1001 0 Error Register Unsigned8 RO Error register for the NCAN-02. Bit-encoded according to DS301/401.
Bit value 1 = Error occurred.
1003 0 Pre-defined Error Field Unsigned8 RO Number of errors occurred and listed at Sub-indexes 1 to A. Writing a
zero here deletes the list.
1 Pre-defined Error Field Unsigned32 RO List of errors.
The most recent error is at Sub-index 1. When a new error occurs,
previous errors move down the list. Error numbers comprise a 16-bit
error code (listed in Appendix B) and a 16-bit additional information
field (0 with NCAN-02). The error code is contained in the lower 2 bytes
(LSB), the additional information in the upper 2 bytes (MSB).
