4.2 Drive Functional Description
The 2001 Series controller utilizes a 16-bit microprocessor based, keypad programmable, variable speed AC
motor drive. There are four major sections: an input diode bridge and filter, a power board, a control board, and
an output intelligent power module.
4.2.1 Drive Operation
Incoming AC line voltage is converted to a pulsating DC voltage by the input diode bridge. The DC voltage is
supplied to the bus filter capacitors through a charge circuit, which limits inrush current to the capacitors during
power-up. The pulsating DC voltage is filtered by the bus capacitors, which reduces the ripple level. The
filtered DC voltage enters the inverter section of the drive, composed of six output intelligent insulated gate bi-
polar transistors (IGBTs), which make up the three output legs of the drive. Each leg has one intelligent IGBT
connected to the positive bus voltage and one connected to the negative bus voltage. Alternately switching on
each leg, the intelligent IGBT produces an alternating voltage on each of the corresponding motor windings. By
switching each output intelligent IGBT at a very high frequency (known as the carrier frequency) for varying
time intervals, the inverter is able to produce a smooth, three phase, sinusoidal output current wave which
optimizes motor performance.
