BL series amplifiers are highly reliable linear brushless servo amplifiers that are easily adaptable to drive brush or brushless servomotors. The BL amplifier package is a complete modular unit that includes heat sink, metal cover, control, and bus power supplies that operate at ±40 VDC (@ 20 amps peak) or ±80 VDC (@ 10 amps peak). The BL drives provide the designer with servo drive flexibility for use in applications such as CMM (Coordinate Measurement Machines), X-Y stages, inspection and scanning, medical device fabrication, and semiconductor fabrication.
The BL drives feature a self-commutation mode using analog or digital Hall effect feedback signals. The BL drives even 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 in current (torque) mode, velocity mode, etc.
Complete electrical isolation is provided between the control stage and the power stage for all models of the BL series. This is accomplished with a transformer-isolated control voltage power supply and opto-isolation of the drive signals, current command signals, and fault signal between the control and power stages. Each drive is fully protected against control power supply under voltage, rms current limit exceeded, power stage bias supplies under voltage, over temperature, over current, and excessive power transistor dissipation.
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. In addition, the BL drive can drive three individual brush motors in torque mode.

- Actual peak and continuous output current is load dependent.
- The BL series can drive each of its phases rail to rail since the drive supply for each phase is not derived from the ± bus voltages.
- This specification based on the output power transistors in the saturated (e.g., full on) condition.
- Driving BLM-203-A (RLL = 4 W, LLL = 3.2 mH)
