Models, Options and Packages

The BA drives are available in three models with continuous power, ranging from 1,360
to 4,080 watts. A list of these models and the available voltage configurations is shown in

The BA drives feature self-commutation with Hall effect feedback signals.
operation is also available for the BA drives. The BA drives include a 5 VDC, 250 mA
supply to power encoders and Hall effect devices (HEDs). Each model is jumper
selectable, providing the capability to drive both brush and brushless motors. The heat
sink can be mounted in two different orientations, but it is recommended that this heat
sink be mounted to a larger, thermally conductive surface for further heat dissipation.
Complete electrical isolation is provided between the control stage and the power stage
for all models of the BA series. This is accomplished with a transformer isolated control
voltage power supply and opto-isolation of the drive signals, current feedback signals and
fault signal between the control and power stages. Each drive is fully protected against the
following fault conditions:
½ control power supply under voltage
½ RMS current limit exceeded
½ power stage bias supplies under voltage
½ over temperature
½ over current
½ output short circuits (phase to phase and phase to ground)
½ DC bus overvoltage.
Operating modes include current command, velocity command or dual-phase command
(for brushless modes of operation only). For brush modes of operation the available
operating modes are current command and velocity command. Differential inputs are used
for better noise immunity. Velocity feedback is from either an encoder or tachometer and
logic inputs include directional current limits and shutdown. Fault, current, and velocity
outputs simplify monitoring drive status.
