ENC Status Compact

Input data of the encoder interface

 

Status

 

 

  • Latch C valid

New data are available in the process data Latch value. Reset via Enable latch C

 

  • Set counter done

Acknowledgement for setting the Set counter

 

  • Counter underflow

The counter is lower than the lowest counter value that can be displayed

 

  • Counter overflow

The counter is higher than the highest counter value that can be displayed

 

  • Open circuit

One of the channels (A, B or C) has an open circuit (configurable for each channel via CoE)

 

  • Extrapolation stall

Micro-increment value invalid (when micro-increment evaluation is enabled -> index 0x8000:0A)

 

  • Status of Input A, B,C

Status of inputs A, B, and C

 

  • Sync error

EtherCAT error, see EtherCAT system documentation

 

  • TxPDO State

See object description

 

  • TxPDO Toggle

See object description

 

Counter value

Current encoder counter value

 

Latch value

Counter value of the encoder with rising edge at the latch input

ENC Control Compact

Output data of the encoder interface.

 

Control

 

 

  • Enable latch C

Input C is activated. When an edge is encountered, the Counter value is stored in Latch value.

 

  • Set counter

When a positive edge is encountered, the Set counter value is transferred to the Counter value

 

Set counter value

Preselection value for Counter value
