Drive Status
Description: Class 3 diagnostic (C3D). Drive operation status flags.
When a condition changes in the drive, the corresponding bit changes in the C3D, this sets the change bit for C3D
in the SERCOS drive status (bit 11) to a binary '1'. When the C3D is read via the service channel, the C3D change
bit is reset to '0'.
Enumerated Bit Pattern:
Structure of C3D:
Bit 0: nfeedback = ncommand (see parameter 330) “At_Prog_Speed”
Bit 1: nfeedback = 0 (see parameter 331) “Zero Speed”
Bit 2: n

Description: Manufacturer version. The operation data of the manufacturer version contains the actual version
and additional information of the manufacturer. The structure of the manufacturer version appears as:
Vers: 01.001, where the first 2 numbers are the major revision and the second 3 numbers are the minor revision.
