GalilMotion Control'stwo multi-axis servo drives perform sinusoidal commutation. The AMP-43540contains four 600W servo drives and the AMP-43640 contains four 20W servodrives. Both models are sinusoidally commutated for minimized torque ripplecompared to drives using trapezoidal commutation. This is important forapplications using low friction linear motors.

The AMP-43540 and AMP-43640 4-axis drives areavailable as options for Galil's DMC-40x0 Accelera and DMC-41x3 Econo motion controllers with Ethernet. Designed to minimize space,cost and wiring, the drives reside directly inside the controller enclosure.The DMC-4040 4-axis controller and drive package dimensions are 8.1 x 7.3 x 1.7inch. Two 4-axis drives can also be installed inside the DMC-4080 8-axiscontroller package which measures 11.5 x 7.3 x 1.7 inch.

The AMP-43540 contains four 600W fully digital,transconductance amplifiers for driving brushless motors with sinusoidalcommutation. Each amplifier drives motors operating at up to 8A continuous, 15Apeak, 20-80V dc. The gain settings of the amplifier are user-programmable at0.4, 0.8 and 1.6 A/V. Both the switching and sampling frequencies are 33 kHz.The amplifier offers protection for over-voltage, under-voltage, over-current,short-circuit and over temperature. A shunt regulator option is available.

The AMP-43640 contains four 20W linear,transconductance amplifiers for driving brushless motors with sinusoidalcommutation. Each amplifier drives motors operating at up to 1A peak, 15-30V dcwith a gain setting of 0.1A/V.

When using the AMP-43540 and AMP-43640sinusoidal drives, hall sensors are not required for brushless motorcommutation. Galil provides commands for initialization of the motor using theencoder feedback.
