SIMOTION C230-2, 04.2003 Edition
Types of encoder that can be connected
Both rotary (shaft encoders, angle measurement systems) and linear (linear en-
coder, linear measurement systems) measuring systems can be used. These can
be built on the machine/system (incremental encoder) or integrated in the motor
(rotor shaft angle encoder).
The following table gives you an overview of the encoders that can be connected
and what you should take into account here.

Note
If you operate drives via the PROFIBUS DP, you do not need to connect any en-
coders to this interface. The encoders are connected directly to the drive.
Encoder emulation (incremental shaft encoder (WSG) interface)
If the drive unit is equipped with encoder emulation, this can be connected instead
of an encoder. The drive control analyzes the information from a rotor shaft angle
encoder and provides information on the actual position to this interface by emulat-
ing the signals of an incremental encoder.
Note
Please note the drive manufacturer’s wiring specifications. As the encoder inter-
face of the C230-2 is non-isolated, in individual cases it may be necessary to take
special measures in respect of EMC.
