Fixed from:
Servo inverter i950 FW: from V01.10.00
Behavior of the new version:
It may now also single-turn HIPERFACE-DSL encoder types with one total resolution of <= 23 bit be used.
Description of behavior:
Some singleturn HIPERFACE-DSL encoder types are not with Lenze inverters operable, because they are not conform to specification HIPERFACE-DSL of Sick Sick behavior. Lenze internal investigations have shown that not all encoder types from manufacturer Sick of specification . Some encoder types provide an incorrect encoder_ID and therefore a an incorrect total resolution, so that an operation with Lenze converters possible . style="font-family: Calibri; font-size: 14.6667px;">
Terms and Conditions under which the behavior occurs:
Not affected are: All of Lenze are: motors with OCT encoders are also compatible with Lenze converters . style="font-weight:400;font-family:Calibri;font-size:14.6667px;">It are generally only OCT encoder types are used, on which the described restriction does not apply. style="font-weight:400;font-family:Calibri;font-size:14.6667px;">
Only OCT encoders with a total resolution style="text-decoration-line:underline;">total resolutionof<=23 bits are affected affected, which only on a few style="text-decoration-line: underline;">single-turn encoders
. All known known multiturn encoders have a significantly above total total resolution . style="font-family:calibri;font-size:14.6667px;font-weight:bold;">
The total resolution is as follows as follows:
Single turn total resolution = "Resolution per revolution"Multiturn total resolution = "Resolution per revolution" plus 12 bits (for 4096 multiturn revolutions).Example;
Resolution per revolution = 16 bit Multiturn revolutions = 12 Bit
Total resolution = 28 Bit
Example example: OCT encoder Sick EDS35 (single turn):
Resolution per revolution | Security-oriented System | Type | Item no. | Transferred Encoder_ID |
20 bit | ✔ | EDS35-2KF0A020A | 1090710 | Incorrect |
EDS35-2KF0A020A-40 | 1112142 | Incorrect |
- | EDS35-0KF0A020A | 1090708 | Incorrect |
24 bit | ✔ | EDS35-2KF0A024A | 1090734 | OK |
- | EDS35-0KF0A024A | 1090732 | Ok |

Short-term measures, Recommendations, Rating:
Single turn onlyHIPERFACE-DSL Use encoders with a total resolution of >= 24 bits.
