2.6 Control Terminals
Control terminals must be programmed. Each terminal has specific functions it is capable of performing and a numbered parameter associated with it. See table
Control Terminals and Associated Parameters. The setting selected in the parameter enables the function of the terminal.
It is important to confirm that the control terminal is programmed for the correct function.
Parameter settings are displayed by pressing the [Status] key on the
Keypad.
Use the arrow keys [

rameters.
See the Programming Guide for details on changing parameters and the functions available for each control terminal.
In addition, the input terminal must be receiving a signal. Confirm that the control and power sources are wired to the terminal. Then check the signal.
Signals can be checked in two ways. Digital input can be selected for display by pressing [status] key as discussed previously, or a voltmeter may be used to check
for voltage at the control terminal. See procedure details at Input Terminal Test in Section Test Procedures.
In summary, for proper frequency converter functioning, the frequency converter input control terminals must be:
1. wired properly
2. powered
3. programmed correctly for the intended function
4. receiving a signal
