With an oscilloscope and differential probes the EMC noise level on the HDSL-lines
can be checked. Within (HIPERFACE DSL
®
field test & analysis – Possibilities and
limits Application Note Vers. 12-00; Doc. E_148498) some test possibilities are
described. This can be done during different servo controller operation modes like
acceleration, deceleration, stand still, reverse cycling at free running mode or with
motor load.

By modifying connections and/or shielding performances changes can be checked
for optimization purposes.
10.2
Motor recommendations
The servo motor part within the system configuration contains the motor connector, the
encoder connecting set and the encoder as well.
10.2.1
Motor connector
In principle the information provided at
apply here, too. Depending on
the motor power size currently the two different sizes are in use: M17 and M23, the last
one is the mainly used size. For interchangeable components the 9-pin layout version
should be used as shown at
(e.g. Intercontec connector series 923)
For both the connector sizes there are the same criteria applicable:
•
Keep open (= unshielded) wire lengths as short as possible, especially for the data
wires (< 20 mm).
•
Keep data wires well separated from power and brake wires, no cross overs
between data and other wires.
•
Connect the shielding via areal contact to the connector (no pigtails).
•
Data line shielding gets its own contact through the connector.
For connecting and assembling the particular connector follow the according instruc‐
tions of the manufacturer.
10.2.2
Encoder connection set
With the encoder connecting set the encoder is connected to the motor connector
inside the motor. SICK provides this configured cable set as an accessory. Here the
wires are already assembled to the connector for the HDSL-connection to the encoder.
For the connection between the encoder to the motor connector the length shall be
minimized without any loops, unused wire lengths shall be cut-off. By using a connec‐
tion set without shielding which is typical for small and midsize servo motors (frame
sizes up to 130 mm) the data line shielding at pin F needs to be connected to PE at the
motor housing. When using a shielded connection set (for connections lengths >200
mm) this shielding is connected to pin F. In this case the connector series 723 (of Inter‐
contec e.g.) is used for the motor connection (at the motor and cable as well) to opti‐
mize data line shielding performance. At the encoder side this shielding is connected to
the encoder housing and by special measures inside the encoder to PE finally.
10.2.3
Encoder mounting
For a proper and long reliable function the encoder needs to be assembled according
the information within its operation instructions. If necessary the required special tools
shall be used and the listed torque setting. Tools with adjustable torque setting shall be
used for repeatable mounting conditions. Motor temperature sensor leads shall be cut
to a reasonable length before configured with the connector to connect to the encoder.
Long loops of these leads shall be avoided.
