Parker Compumotor (Rohnert Park, CA), a division of Parker Hannifin Corp., introduced its new small, low-voltage, digital (SLVD) drives that measure 5.56in x 3.39in x 5.49in, and deliver shaft powers of up to 620W. The SLVD servo drives can be used for position, speed or torque control, and are capable of handling simple position-control functions such as following and electronic cam profiling.
Designed for direct online operation from a standard 240Vac main supply, the SLVD servo drives are available with a choice of three power output stages, offering current ratings of 1.25A, 2.5A and 5A continuous RMS (2.5A, 5A and 10A peak RMS). High-frequency switching techniques are employed to maximize performance and efficiency, and to reduce internal heat dissipation. The drives can be used with any standard three-phase, brushless, servo motor that uses sinusoidal commutation and resolver feedback. The drive also offers industry-standard, step-direction and ±10V analog-control inputs, for users who wish to migrate existing machines to modern servo technology without changing host controllers.
