CONTROL/DISPLA Y BOARD The Control/Display Boar d assembly is actually two boards mounted together . They should be replaced together . The Display portion houses the control panel, LEDs, push buttons and output encoders. The Display Boards functions as the interface between the user and the V205-T machine.
INSULA TED GA TE BIPOLAR TRANSIST OR (IGBT) OPERA TION An IGBT is a type of transistor . IGBT are semiconduc- tors well suited for high frequency switching and high current applications. Example A in Figure E.6 shows an IGBT in passive mode. There is no gate signal, zer o volts relative to the source, and ther efore, no curr ent flow .
