2.5 Frequency Converter Inputs and Outputs
The frequency converter operates by receiving control input signals. The frequency converter can also output status data or control auxiliary devices. Control
input is connected to the frequency converter in three possible ways. One way for frequency converter control is through the Keypad on the front of the frequency
converter when operating in local (hand) mode. These inputs include start, stop, reset, and speed reference.
Another control source is through serial communication from a serial bus. A serial communication protocol supplies commands and references to the frequency
converter, can program the frequency converter, and reads status data from the frequency converter. The serial bus connects to the frequency converter through
the RS-485 serial port or through a communication option card.
The third way is through signal wiring connected to the frequency converter control terminals (see illustration below). The frequency converter control terminals
are located below the frequency converter Keypad. Improperly connected control wiring can be the cause of a motor not operating or the frequency converter
not responding to a remote input.
