A diode bridge converts line power almost entirely to active power. The displacement power factor approaches unity (>0.98) regardless of the speed or load of the connected motors.
The DC-Intermediate Circuit filters the DC-voltage ripple supplied by the Rectifier Stage. This section consists of an inductor and capacitors, as well as a charging circuit. The charging circuit limits the in-rush current when power is applied by directing the current through a resistor. Once the bus is charged, the resistor is shorted with a relay or SCR. Note: 600 VAC units have an AC choke in place of the DC choke.
Note: The maximum number of chargings in one minute is four. In applications where frequent start/stop is required, electronic start/stop should be used with the unit powered continuously.
The Inverter Stage forms symmetrical three-phase AC voltage from the constant DC voltage supplied by the DC-Intermediate Circuit.
A Motor Control Card controls the Inverter Stage and monitors the operation of the ACS 501.
A Control Interface Card is the link between the operator and the ACS 501. It features a Control Panel with an alphanumeric display and keypad. A terminal block for external control connections is also located on the Control Interface Card.
The Control Interface Card is optically isolated from the line potential. The Control Interface Card common is connected to the chassis ground through a 10 megohm resistor.
