34 EM-ABS-01 for ACU 03/12
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.
Note: If the data track cannot be evaluated, error “F1719 Di
. encoder: Protocol
error” will be triggered. In this case, check
Tracks/Protocol 1184 setting.
Note: 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
uarantees a very hi
h positionin
and speed accuracy at all
supported transmission rates.
6.5 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.
his
function is being prepared and is currently not supported!
Note: 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 positionin
(and not for speed feedback),
you can also use a SSI encoder without incremental tracks.
HTL tracks cannot be used as incremental tracks.
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 confi
uration (mains volta
e or
DC 24 V).
Step 3: Configure the frequency inverter according to the following parameters.
• Set Tracks/Protocol 1184 according to the encoder data sheet (please see
chapter 8.4.2).
SSI operation modes key:
Note: If a SSI encoder without incremental trac
(Tracks/Protocol 1184 = 50xx or 60xx) is used for positionin
, the speed
of the data track must be as high as possible for optimum control quality.
The usable transmission rate depends on the length of the encoder cable.
