Product Description:
The BDS5A-220-40110\816A4-030 is a digital servo drive manufactured by Kollmorgen within the BDS Industrial Servo Drives series. Designed for closed-loop motion platforms, the unit converts three-phase mains power into controlled armature currents for brushless servomotors used in material-handling systems, pick-and-place axes, and packaging lines. It communicates through an integrated RS-232 port for parameter downloads and diagnostics. The drive accepts resolver feedback to synchronize its output with the rotor position and maintain accurate motor control.
During continuous operation, the drive delivers a steady current of 20.0 A, while short acceleration bursts can draw up to 40.0 A; these limits establish the thermal requirements for cables and protective devices. It supplies 8.0 kVA of continuous electrical power to the motor and up to 16.0 kVA during transient peaks, allowing machines to overcome inertia without an oversized power stage. The input section is rated for 230 VAC and includes line filtering. Its width is limited to 98 mm, allowing multiple axes to fit in standard control enclosures. Thirty-two discrete I/O channels connect the drive to limit switches or PLC logic, and internal heat dissipation remains 150 watts under nominal load. Resolver conversion accuracy is 8 arc minutes with 14-bit resolution, supporting positioning increments of 0.024 degrees at the shaft.
For precise torque modulation, the inverter refreshes its output transistors at a pulse-width modulation rate of 10.0 kHz. Motor current ripple is further smoothed by a commanded sine table that repeats each mechanical revolution at 20.0 kHz. The command interface accepts a bipolar control signal of up to ±10 V, allowing direct connection to analog motion cards. A built-in position counter interpolates resolver signals to 16,384 counts per revolution, providing fine granularity for indexing and contouring. A resolver excitation frequency of 8.5 kHz supports stable position tracking while keeping conducted emissions low.
