STO signal must be provided in order to permit running the motor. Start/Stop commands and speed reference are provided by serial
communication. In Modbus mode, the digital input and analogue input can be used as remote I/O by the controller, the relay output
can also be configured to be controlled by Modbus and used by the controller if required.
