EnDat 2.1 encoders

This chapter describes how EnDat 2.1 encoders are commissioned.
Note:
Note:
Step 1: Install the EM-ABS-01 as described in chapter 5.2. Do not connect the encod-
er cable yet.
Step 2: Turn the frequency inverter on for parameter configuration (mains voltage or
DC 24 V).
Step 3: Configure the frequency inverter according to the following parameters.

If the data track cannot be evaluated, error "F1719 Dig. encoder: Protocol
error" will be triggered. In this case, check
When the frequency inverter is turned on, the absolute position is read via
the data tracks. Via the incremental tracks, the position is counted up in-
ternally and compared to the updated absolute position at regular inter-
vals. This guarantees a very high positioning and speed accuracy at all
supported transmission rates.
Only EnDat 2.1 encoders with SinCos tracks can be connected.
The EM-ABS-01 module supports, in the case of EnDat 2.1 encoders, a
baud rate of 100 kBit/s. Other baud rates will not be supported.
Adjust the
Division marks
Chapter 8.4.1), in the case of EnDat 2.1 encoders, the value is typically 512
amplitudes/turn, (e.g. Heidenhain ECN 1113, EQN 1125).
Set 1184 to value 1101 (please see chapter 8.4.2).

Adjust the
Supply voltage
Chapter 8.4.4), in the case of EnDat 2.1 encoders, the value is typically 5.0V.
Adjust 1186 according to the connections (see chapter 8.4.3).
Power supply
Bonfiglioli Vectron recommends evaluating the sense line (settings: "5-intern,
Sense" or "6-Via X410A, Sense").
Attention: Always set the
