Removal
1. Unscrew the screws (1) and remove the cover (2).
2. Pull out the balancing weight (3).
3. Unscrew the screws (4) and remove the cover (5).
4. Scanning unit:
–
Unscrew the screw (6).
– Remove the connector (8) for the signal cable.
– Remove the screws (9) with washers and remove the scanning unit (10).
5. Toothed wheel:
–
Pull off the toothed wheel (11).
Mounting
Mount the toothed-wheel encoder in the reverse order to the order in which you removed it,
with the following differences:
1.
Heat up the toothed wheel (11) (approx. 150 °C), push it onto the motor shaft (12) and
allow it to cool down.
2. Lock the screws (9) for attaching the scanning unit (10), e.g. with Loctite 243.
3. Observe the mounting dimensions (see Fig. "Installing the toothed-wheel encoder").
8.2.4 Replacing the DRIVE-CLiQ interface (encoder module)
WARNING
Danger to life when using an incorrect encoder module
The DRIVE-CLiQ encoder contains motor and encoder-specific data and an electronic type
plate. If you use an incorrect DRIVE-CLiQ encoder, this can result in death, severe injury
and severe material damage.
• Only use the DRIVE-CLiQ encoder and the electronic type plate for the original motor.
•
Do not mount the DRIVE-CLiQ encoder onto other motors.
• Do not replace a DRIVE-CLiQ encoder by a DRIVE-CLiQ encoder belonging to another
motor.
•
Only appropriately trained Siemens service personnel should replace DRIVE-CLiQ
encoders.
