Galil
Motion Control's
two multi-axis servo drives perform sinusoidal commutation. The AMP-43540
contains four 600W servo drives and the AMP-43640 contains four 20W servo
drives. Both models are sinusoidally commutated for minimized torque ripple
compared to drives using trapezoidal commutation. This is important for
applications using low friction linear motors.
The AMP-43540 and AMP-43640 4-axis drives are
available 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 1.7
inch. Two 4-axis drives can also be installed inside the DMC-4080 8-axis
controller 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 sinusoidal
commutation. Each amplifier drives motors operating at up to 8A continuous, 15A
peak, 20-80V dc. The gain settings of the amplifier are user-programmable at
0.4, 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 sinusoidal
commutation. Each amplifier drives motors operating at up to 1A peak, 15-30V dc
with a gain setting of 0.1A/V.
When using the AMP-43540 and AMP-43640
sinusoidal drives, hall sensors are not required for brushless motor
commutation. Galil provides commands for initialization of the motor using the
encoder feedback.
