Technical parameters of the inverter controller:

• 2×16 character LCD display, with LED backlight;
• 6-button keyboard;
• 4 LEDs indicating the operating status;
• RS-485 interface, used to communicate with the inverter using the MODBUS RTU protocol;

The inverter controller was designed to control the cyclic operation of the inverter which was connected to a 3-phase motor. Parameter settings are made from the keyboard and are displayed on a 2×16 character LCD display. The controller communicates with the inverter via a serial RS-485 connection, MODBUS RTU protocol. The operating status is indicated by LEDs.

The controller enables the engine to operate according to the following parameters:

• engine speed;
• turning direction;
• turn on, turn off the engine;
• engine operating time at a specific speed.
