03/12 EM-ABS-01 for ACU 31
6.2 SinCos encoders
This chapter describes how SinCos encoders are commissioned.
Note: If a SinCos encoder is used as a motor encoder on a synchronous servo-
motor, the SinCos encoder must also feature, in addition to si
nal tracks
/B, commutation tracks C/D (e.
. Heidenhain ERN 1185).
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 SinCos encoders, the value is typically 1024
pulses/turn.
• Set
Tracks/Protocol 1184 to value 100, 300, 500 or 700 (please see chapter
8.4.2).
• Adjust the
Supply voltage 1187 accordin
to the encoder data sheet (see
Chapter 8.4.4), in the case of SinCos encoders, the value is typically 5.0V.
• Adjust
Power supply 1186 according to the connections (see chapter 8.4.3).
Bonfiglioli Vectron recommends evaluating the sense line (settings: “5-intern,
Sense” or “6-Via X410A, Sense”), if available and connected.
Attention: Always set the
Supply voltage 1187 first and then set Powe
supply
1186.
• 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 SinCos Geber to the EM-ABS-01. Bonfiglioli Vectron recommends
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.
Note: SinCos encoders are no absolute value encoders. In configurations “Posi-
tioning” x40 you will have to carry out a referencing operation with SinCos
encoders after mains on.
