DPF72004 - 4 Axis, Bilevel, Unipolar Driver Pack
Bilevel Drive Operation
The DPF72003 and DPF72004, One and Two Axis Driver Packs contain Anaheim Automation's latest driver technology, which includes protection against shorted motors or open motor connections. These models feature 600 Watt Power Supplies and output current capability of 10 amps peak (7 amps continuous). If either a short or open circuit occurs, a Fault LED turns on and the driver shuts down. Like other Anaheim Automation Step Motor Drivers, the DPF72000 Series uses a bilevel drive technique. High voltage is applied to rapidly build up the current in the motor windings and a low voltage is used to sustain the current. This bilevel drive technique achieves outstanding motor performance without high frequency switching as used in chopper drives. Therefore, there are little or no EMI or RFI problems, and motor heating is greatly reduced.
