Step 4: Turn the frequency inverter off.
Step 5: Connect the EnDat 2.1 Geber to the EM-ABS-01. Bonfiglioli Vectron recom-
mends the use of pre-assembled cables (see chapter 5.3.2.1).
Step 6: Turn the frequency inverter on.
Step 7: Check the encoder for proper function.
Step 8: In configurations "Positioning" x40: Carry out referencing operation once.

SSI encoders

This chapter describes how SSI encoders are commissioned. You can connect SSI
encoders with binary evaluation and SSI encoders with Gray code evaluation.

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

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.
For a correct function of the speed control, an SSI encoder with incremen-
tal tracks (TTL [RS-422] level or SinCos tracks) must be used.
If the SSI encoder is used for positioning (and not for speed feedback),
you can also use a SSI encoder without incremental tracks.
HTL tracks cannot be used as incremental tracks.
Set 1184 according to the encoder data sheet (please see
