IO-Link Absolute Encoder: Position Reconstruction After Power-On Is Missing Due to Offset Storage

     

Description of the behavior: 


The offset is stored in parameter 0x500B:086. The parameter can be defined manually or using the homing function. After definition, the save button or 0x2022:003 must be activated; otherwise, the value will be lost when the power is turned off. 


The additional parameter 0x500B:085 defines whether “Drive homed” (0x5030:110, bit 5 or 0x500A:005, bit 5) is permanently set, and positioning can begin immediately.


Note: This function currently has errors. 

  • Executing the homing function twice has a negative effect on the offset. 0x500B:086 must be manually set to 0 to correct the homing. 
  • "Drive homed" is always true, regardless of whether an IO-Link sensor is connected or not.
