The LVD Sercos III is a compact, high-power and intelligent servo drive for low voltage 1548 VDC bus servo motion applications. The drive is for use with small low voltage brushless, stepper or brushed DC motors. In the case of stepper motors, the control is done through a closed loop commutation with no step loss.
The LVD has been qualified by Bosch Rexroth to operate with the IndraMotion Control models, MLC motion logic control, MLD drive-integrated motion control, and MTX CNC platform.
The drive is about the size of a smartphone, and weighs just 250 grams – making it one of the smallest drives available. It has 12 Arms peak current and a switching frequency of up to 100 KHz.
The drive’s high PWM switching frequency, combined with the field oriented control (DQ) and space-vector modulation, enables operation of low inductance motors while minimizing current ripple and eliminating acoustic noise. Separate logic and bus power supplies allow safe motor power-off while maintaining the drive state, and a fast restart.
