Product Description:

The B8962-FK1 is a brushless servo smart drive produced by Kollmorgen within the B8000 Brushless Servo Smart Drives series. It functions as a compact motion controller that coordinates two servo axes and supplies regulated current to matched motors. This allows precise positioning, velocity regulation, and electronic gearing in automated machinery. The integrated format is useful in compact machines where coordinated multi-axis motion is required without a separate external control rack.

This unit controls 2 axes and accepts up to 2300 VA of single-phase power at 115 VAC. Under steady load, it delivers a continuous phase current of 5 A, while short bursts can reach 10 A during acceleration or shock loading. This current range supports normal running conditions as well as brief demand spikes created by rapid index moves or abrupt load changes. Drive-to-host communication over the auxiliary port is fixed at 9600 baud. Eight discrete inputs and eight discrete outputs are available; each input draws 12 mA when active, and each output can sink 100 mA for relays or indicators. Thermal management uses a clip-on fan that increases enclosure depth by 1.05 in, and the controller initiates a protective shutdown if the heat sink reaches 55 °C.

The feedback stage supports encoder signals up to 2 MHz. This allows tight loop bandwidth when paired with the differential quadrature incremental encoders used in the series. Position tracking is performed at a system resolution of 8,000 counts/rev, while the sensor header furnishes a stabilized supply of +5 VDC @ 200 mA for the encoder electronics. Diagnostic and parameter loading tasks are handled through a RS-232C serial link that shares the command channel with the programmable I/O. These feedback and communication resources support interpolation, homing, and motor commutation without an external motion card.
