Object Dictionary
About this reference
This reference follows the drive EDS file tl-7230.eds and covers every standard and manufacturer object of WD-DRIVE_TL7230_V1 (vendor WEI DONG DRIVE, EDS version 4.0). Parameter names, data types and default values match the EDS so they can be checked item by item against the host tool (wddrive-studio) and the master configuration.
The EDS describes design values; a given firmware revision may differ slightly. Always trust the value read back from the device.
Object ranges
Following the CANopen convention, the object dictionary is split into the following pages:
| Page | Index range | Description |
|---|---|---|
| Communication objects | 0x1000–0x1FFF | CiA 301 communication objects: device info, error register, heartbeat, SDO, RPDO/TPDO and NMT startup. |
| CiA402 objects | 0x6000–0x6FFF | Drive and motion control profile objects: status/control word, modes of operation, position/velocity/torque and homing. |
| Manufacturer objects (0x2000) | 0x2000–0x2FFF | Real-time status monitoring, protection, control-loop tuning, filtering and homing on block. |
| Manufacturer objects (0x3000) | 0x3000–0x3FFF | Motor parameter identification and calibration (resistance/inductance/encoder direction/phase/cogging). |
Legend
- Index:sub-index: objects are addressed by a 16-bit hexadecimal index such as
0x6041; an object with sub-indexes is writtenindex:sub-index, where the sub-index is 8-bit hexadecimal. Here each object is titled0xXXXXand its sub-indexes are listed in the “Sub” column of the table (VARobjects only have00). - Object type:
VARis a single-value object;ARRAYis an array of one data type;RECORDis a record that may mix data types.
Data types are:
| Code | Meaning |
|---|---|
| 0x0001 | BOOLEAN |
| 0x0002 | INTEGER8 |
| 0x0003 | INTEGER16 |
| 0x0004 | INTEGER32 |
| 0x0005 | UNSIGNED8 |
| 0x0006 | UNSIGNED16 |
| 0x0007 | UNSIGNED32 |
| 0x0008 | REAL32 |
| 0x0009 | VISIBLE_STRING |
| 0x000A | OCTET_STRING |
| 0x000B | UNICODE_STRING |
| 0x000F | DOMAIN |
- Access:
ROread-only;WOwrite-only;RWread/write;RW (RPDO)/RW (TPDO)means the object can be mapped into the corresponding PDO;CONSTconstant. Read-only objects can only be read over SDO. - PDO column:
✓means the object (or sub-index) can be mapped into a PDO,—means it is not mappable and is only reachable over SDO. - Notes:
Range a–bis the lower/upper value limit declared in the EDS;P(PERSIST_COMM) means the value is stored in non-volatile memory and survives power-off, whereas other objects revert to their default value.
