Product Description:

The LE06300 servo drive is built by Kollmorgen as part of the SERVOSTAR CD Drives series. It is a digital amplifier that conditions DC bus power and delivers phase-synchronized output to brushless servo motors used in CNC machinery, material handling, and automated assembly. Inside the housing, a 40 MHz DSP works with an embedded controller to handle motion calculations and protective diagnostics. The drive regulates motor torque and speed so that external controllers obtain predictable mechanical responses under changing load conditions.

The drive accepts an analog command range of ±10 VDC and provides a serial setup link through RS-232, so configuration software and legacy control cards can issue motion requests. Current regulation is executed at 16 kHz using a pole-placement algorithm, while the velocity loop runs at 4 kHz with a PDFF profile that filters derivative noise without adding steady-state error. Continuous motor current is limited to 6 A, yet the output can reach 18 A for 0.5 seconds during brief acceleration bursts. These electrical limits and the incoming encoder data establish the operating range monitored by the DSP to prevent overcurrent trips and maintain stable motor control.

An integrated 5 VDC encoder supply delivers 250 mA to digital position sensors, allowing compatible feedback devices to receive low-voltage power directly from the drive. The feedback port supports frequencies up to 3 MHz and line counts as high as 10,000,000, giving the controller fine-grained position data for accurate commutation and motion correction. Signal integrity is maintained when the motor cable does not exceed 50 ft (15 m), matching typical cabinet-to-axis distances and reducing exposure to signal degradation over longer runs. Encoder data returns the rotor position to the internal control loops, which use this information to correct phase timing and velocity response as the load and speed change.
