Sinusoidal Commutation Goes Standard at Galil - 2/2
proportional currents. Because the sum of all three phase currents must be zero, the
amplifier easily constructs the third current. An optical encoder attached to the motor
shaft reports the motor position enabling the controller to determine the commutation
phase.
To effect the sinusoidal commutation, one must initialize the commutation phase.
Galil provides several initialization methods including the most common, Hall sensors.
The sinusoidal commutation feature is configurable by the user on all DMC-1700 and
DMC-1600 controllers and is available at no extra charge.
Galil's Product Line
Galil's array of motion controllers are designed to solve complex motion
problems for such applications as jogging, point-to-point positioning, vector positioning,
electronic gearing, electronic CAM, multiple move sequences and contouring. Galil's
newest product is their DMC-1600 Series of Compact PCI Bus controllers, featuring
Eurocard design and `plug and play' installation. The DMC-1700 Series of ISA Bus
motion controllers allow up to 8 axes on a single card. The DMC-1400 Series provides
an economical, `half-size, half-price' solution for 1-axis applications, while the DMC-1500
Series are stand-alone motion controllers that provide intelligent, precise control without
a host computer.
