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.
