Analog outputs and Wideband Modulation
Radonix’s PC-Smart series models feature analog outputs. These outputs are referred to as “Analog Out [n]” or “A[n],” where n represents a number greater than or equal to zero. Analog outputs provide a continuous voltage between 0 and 10 volts.

These outputs are protected against short circuits to the negative terminal of the power supply and static electricity. However, they can be damaged if directly connected to voltages higher than 10 volts.
The way analog outputs are connected to inverters to control spindle speed is shown in Figure 14.

Due to their high impedance, analog inputs and outputs are very sensitive to noise. Therefore, analog communication cables should not run alongside high-voltage cables or near noise-generating elements. It is recommended to use two-wire cables, and if possible, avoid using multi-core or single-core cables for analog communication.
