Internal Product Review
The PRD-B040ASIB-62 is a Kollmorgen CD Servostar servo drive configured for Goldline submersible motors with resolver feedback. Continuous output at 6 Arms and 12 Arms peak output for 2 seconds give this unit strong dynamic response under changing load conditions. A 16 kHz PWM current ripple frequency with 8 kHz switching supports smooth current regulation in demanding motion applications.

Product Description:
The PRD-B040ASIB-62 drive controller is manufactured by Kollmorgen for the CD Servostar CD Drives series. It supplies regulated three-phase power to Goldline submersible servo motors used in industrial automation cells that require sealed actuation. Mounted in a cabinet slot, the unit processes resolver feedback to align its current vectors with the rotor position, allowing precise torque production. Its embedded analog output stage also shares operating data with supervisory hardware, supporting integration with a higher-level control system.
Under a steady load, the amplifier delivers a continuous motor current of 6 A rms, while brief current transients can be handled with a two-second peak capability of 12 A rms. Current is synthesized through an H-bridge that switches at 8 kHz. The load filters the resulting ripple so that only a residual component at 16 kHz reaches the motor windings. When the DC bus exceeds 430 VDC, the overvoltage trip disables the gate drive to protect the power semiconductors. Analog command information is processed with 12-bit precision, providing fine resolution for speed or position control when the drive is paired with a compatible controller and motor.
A supply decrease below 90 VDC activates the undervoltage trip, preventing incomplete commutation that could stall a motor under load. An internal relay rated at 1 A signals faults to external safety circuits, and its contacts close within 3 ms. Soft-start charging limits inrush current by precharging the filter capacitors over 0.25 s, reducing stress on the input power components when the controller is energized. Upstream circuit protection is provided by a line fuse rated at 15 A. For demanding acceleration events, the drive also supports a 30 A surge rating and can deliver a peak current of 18 A rms for 500 ms, providing additional current for indexing and cyclic machinery.
