HIPERFACE-DSL (OCT): Some singleturn encoder types with a total resolution <= 23 bit are currently not supported (fixed as of V01.03.00)
Fixed from:
Servo inverter i750: from V01.03.00
Behavior of the new version:
It now also single-turnHIPERFACE-DSL Encoder Typeswith one total resolution of <= 23 bit 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 deliver 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 .
It are generally only OCT encoder types are used, on which the described restriction does not applies. style="font-weight:bold;">
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-weight:bold;font-family:calibri;font-size:14.6667px;">
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):
