System and method for motor drive control pad and drive terminals
First Claim
1. A method of controlling a pump driven by a motor, the pump being installed in a well, the motor connected to a drive with a control pad, the drive connected to the motor by an installer, the method comprising:
- providing a drive having an input power terminal block, an output power terminal block, at least one digital input terminal, at least one digital output terminal, and at least one analog input terminal;
connecting at least one of a run/enable switch to the at least one digital input terminal, an indicator device to the at least one digital output terminal, a status output to the at least one digital output terminal, and a fault alarm output to the at least one digital output terminal;
operating the pump in a pump-out mode if sand and dirt need to be discharged from the well; and
automatically entering a password protection mode after a predetermined time period once the installer finishes connecting the drive to the motor and finishes a set up operation.
