Removed from:
Servo Inverter i950 FW: from V01.10.xx (in planning)
Behavior of the new version:
Description of the behavior:
Some singleturn HIPERFACE-DSL encoder types cannot be operated with Lenze inverters because they do not conform to the HIPERFACE-DSL specification from Sick. Lenze internal investigations have shown that not all encoder types from the manufacturer Sick fully comply with this specification. Some encoder types deliver an incorrect encoder_ID and thus also an incorrect overall resolution, so that Boperation on Lenze inverters is not possible.
Conditions under which the behavior occurs:
Not affected are: All motors supplied by Lenze with OCT encoders can also be operated with Lenze inverters.
In general, only OCT encoder types to which the described restriction does not apply are used.
Only OCT encoders with a total resolution of <= 23 bit are possibly affected, which only applies to some singleturn encoders .
All known multiturn encoders have an overall resolution that is significantly higher.
The total resolution is as follows:
Singleturn: total-resolution = "resolution-per-turn"Multiturn: total-resolution = "resolution-per-turn" plus 12 bits (for 4096 multiturn revolutions).Beispiel:
Resolution per revolution = 16 bit Multiturn rotations = 12 bit
Total resolution = 28 bit
Exemplary example: OCT-Encoder Sick EDS35 (Singleturn):
Resolution per revolution | Security-oriented system | type | ArticleNo. | Transferred Encoder_ID |
20 bit | ✔ | EDS35-2KF0A020A | 1090710 | Erroneous |
EDS35-2KF0A020A-40 | 1112142 | Erroneous |
- | EDS35-0KF0A020A | 1090708 | Erroneous |
24 bit | ✔ | EDS35-2KF0A024A | 1090734 | OK |
- | EDS35-0KF0A024A | 1090732 | Ok |
Affected products:
Servo-Inverter i950 FW
Short-term measures, Recommendations, Rating:
Singleturn only HIPERFACE-DSL Use encoders with a total resolution >= 24 bit.
