Key Benefits
Performance
FOC: All Gamma Series employ Field Oriented Control method which allows accurate control in both steady state or transient operation, and optimal orientation of the magnetic field.
Space Vector Modulation: Glentek’s advanced algorithms allow for maximum utilization of the DC bus voltage while generating minimum harmonic distortion of the currents in the winding of 3-phase AC motor.
Digital Current Loops: Current loop bandwidths up to 5 kHz.
DC Sync Rate: as fast as 125µs.
Digitally Tuned: All parameters set digitally. No potentiometers to adjust. DSP control for the ultimate in high performance.
Parametric Filtering: Provides control engineers advanced filtering to eliminate unwanted system mechanical resonance.
Smart-Comm Initialization: Eliminates the need for Hall sensor or commutation tracks for many applications.
Auto Phase Finding: Plug and Play for all types of three phase brushless motors. The drives algorithm will automatically find and align the motor phases.
Auto Phase Advance: Glentek’s advanced algorithms incorporated in the Gamma Series drives, automatically provide phase advance, insuring that the current is delivered at the appropriate time, and provides the most efficient operation.
Sinusoidal Commutation: For the ultimate in efficiency and smooth motion. Commutates from almost any resolution linear or rotary encoder or Hall sensors only.
Fault protection: Short from output to output, short from output to ground, drive RMS over current, drive under/over voltage, drive over temperature, motor over temperature.
On-the-fly mode switching: This feature allows the drive to switch between any mode of operation on-the-fly.
Software configurable: Glentek’s Windows™ based MotionMaestro© software provides ease of set-up, monitoring and tuning with no previous programming experience required.
Silent operation: 25 kHz PWM standard.
Feedback
Encoder feedback: Accepts quadrature encoder signals up to 5 MHz (maximum frequency of up to 10 MHz is possible, but is system dependent). Absolute serial encoder (Biss, EnDat, and T-Format). Analog Sin/Cos encoder.
Encoder Output Divider: The encoder input signal can be divided by a user selectable integer for the encoder output signal. Note: Available upon request only.
Resolver feedback: For resolver feedback the drive creates a simulated encoder output with a typical resolution of 12 bits.
Tachometer feedback: Accepts analog signals from all types of tachometer feedback.
