Replacing an encoder for SIMOTICS motors

For 1FK7 G2, 1FG1 and 1FT7 motors you can replace a defective encoder by an encoder of the
same type. The encoder can be replaced without special tools simply by adjusting the coupling
element opposite the motor shaft. You can recognize the motors mentioned as a result of the
round, raised encoder mounting at the end of the motor enclosure and from the rating plate.
How do you replace an encoder?
An overview of the possible encoder replacement versions is provided below.

Note
Recommendation:
1. Always replace the encoder as a complete component (including the Sensor Module).
2. Use replacement version 1.
Advantage: You order a replacement encoder with a custom-programmed electronic type
plate from your Siemens service organization.
The encoder contains all of the motor data loaded in the factory. You only have to
mechanically replace the encoder, and your system is ready to operate again.
How do you determine the replacement encoder you require?
To replace an existing encoder, you need its article number. You have several options of
obtaining this article number:
● Read off the article number at the encoder
● Determine the article number through Spares on Web (https://www.sow.siemens.com/)
● Determine the article number using assignment tables (see the service instructions)

The encoder contains motor data (an electronic type plate).
The encoder has no motor data.
