32 EM-ABS-01 for ACU 03/12
6.3 Hiperface encoders
This chapter describes how Hiperface encoders are commissioned.
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.
• Adjust the Division marks 1183 accordin
to the encoder data sheet (see
Chapter 8.4.1), in the case of Hiperface encoders, the value is typically 1024
amplitudes/turn (in example SRS50/SRM50).
• Set
Tracks/Protocol 1184 according to the encoder data sheet to value 3109,
3119, 3138 or 700 (please see chapter 8.4.2).
Typical values:
Sick SEK37/S
EL37 & SEK52/SEL52: 9.6 kBaud Æ value 3109
Sick SKS36/SKM36: 9.6 kBaud Æ = value 3109
Sick SRS50/SRM50: 9.6 kBaud Æ = value 3109
• Adjust the
Supply voltage 1187 accordin
to the encoder data sheet (see
Chapter 8.4.4), in the case of Hiperface encoders, the value is typically 8.0 V.
• Adjust
Power supply 1186 according to the connections to “1-internal” or “2-
Via X410A” (see chapter 8.4.3).
In the case of Hiperface encoders, the sens
e line (settings “5-intern, Sense
or “6-Via X410A, Sense“) is typically not used, as it is not defined in the Hiper-
face standard Specification. Thus, usin
the sense line is not required in the
case of Hiperface encoders.
Attention: Always set the
Supply voltage 1187 first and then set Powe
supply
1186.
• Set the number of Bits/Turn 1271 accordin
to the encoder data sheet (see
chapter 8.4.7).
Typical values:
Sick SEK37/S
EL37 & SEK52/SEL52: 9 bits/t
Sick SKS36/SKM36: 12 bits/t
Sick SRS50/SRM50: 15 bits/t
• Set the
Bits Multiturn 1272 accordin
to the encoder data sheet (see chapter
8.4.8),
Typical values:
Sick SEL37, S
EL52, SKM36, SRM50: 12 bits/t
Note: In the case of sin
leturn encoders (e.
. Sick SEK37, SKS36, SRS50), you
will have to set
Bits Multiturn 1272 = 0.
• If the encoder is used as a motor encoder for a synchronous servomotor, set
Offset 1188 according to chapter 8.4.6. This step is not required in the case
of asynchronous motors or if the encoder is used as an application encoder.
Step 4: Turn the frequency inverter off.
Step 5: Connect the Hiperface Geber to the EM-ABS-01. Bonfiglioli Vectron recom-
mends the use of pre-assembled cables (see chapter 5.3.2.3).
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.
