Features:
- PROFIBUS DP exchanges drive setpoints, status and diagnostics with the controller.
- PROFIsafe and local fail-safe I/O form the configured safety communication path.
- Motor data, encoder feedback and the matched power module complete the drive-control loop.
Machine commands enter through the fieldbus or M12-connected local inputs.
The control unit processes those commands and sends gating instructions to the power stage.
Encoder and diagnostic feedback return motor and drive state to the controller.

Keeping standard and safety telegrams distinct
- PROFIBUS DP: Setpoints, control words, status words, and diagnostics use the standard bus channel.
- PROFIsafe: Safety telegrams carry the configured fail-safe commands and acknowledgements.
- Addressing: The fieldbus address and telegram selection match the controller project.
- Acceptance: Safety parameters and every protective function are proved before operation.
Connecting machine signals to the distributed drive
- Standard inputs: Six digital inputs receive operating commands and sensor states.
- Analog inputs: Two 0 to 10 V channels accept analog references or measurements.
- Standard outputs: Two isolated outputs report configured drive conditions.
- Fail-safe signals: Three F-DI and one F-DO connect the local safety circuit.
Closing the control loop around the motor
- Motor data: Nameplate values establish current, voltage, speed, and power limits.
- HTL encoder: Pulse count and direction describe actual motor movement.
- Control method: V/f, FCC, or sensorless vector operation is selected for the load.
- Power stage: The control unit commands the matched G120D power module to energize the motor.
Preserving the settings that define the installed drive
- Project archive: Keep the approved drive configuration and parameter backup.
- Network data: Record PROFIBUS address, telegram, controller assignment, and diagnostics.
- I/O map: Document every M12 input, output, analog signal, and encoder connection.
- Safety proof: Retain the PROFIsafe configuration and signed functional-test results.
