Note
If you want to connect incremental encoders without zero signals, then you must
connect the corresponding pins in the connector with the encoder power supply:
Pin 10 with pin 7 or 9 (MEXT)
Pin 11 with pin 4 or 6 (P5EXT)
Absolute encoders (SSI)
Transmission procedure: Serial synchronous interface (SSI) with 5 V differential

Encoder supply 5 V
The 5 V supply voltage for the encoders is generated inside the module and is
therefore present at the Sub-D socket. This means you can supply the encoders
via the connecting cable without the need for additional wiring. The voltage
supplied is protected electronically against short circuits and thermal overload, and
it is monitored. The encoder supply is not isolated from the load power supply to
the module.
Encoder supply 24 V
For encoders with an operating voltage of 24 V, the 24 VDC power is supplied to
the Sub-D sockets. This means you can supply the encoders via the connecting
cable without the need for additional wiring. The voltage supplied is protected elec-
tronically against short circuits and thermal overload, and it is monitored. The
encoder supply is not isolated from the load power supply to the module.
