MOSFET , Dual H-Bridge, 4 Quadrant
4 state PWM at 20 KHz
0.5 — 3.2 in 0.01 amp increments
Line operated nominal 120-240VAC, 50/60 Hz
Nominal 330VDC (at 240VAC line input)
94—265VAC, 50/60Hz
Over-voltage, under-voltage, over-temp, external output shorts
(phase to-phase, phase-to-ground), inter amplifier shorts
Reduction to any integer percent of full-current after a delay
selectable in milliseconds
Configurations are saved in FLASH memory aboard the DSP
Step & Direction, CW/CCW, Encoder Following, Joystick, SCL
Optically isolated, 5 Volt; Minimum pulse width = 200 ns.
Maximum pulse frequency = 2 MHz. Programmable digital
filter
Depends upon selected resolution; amplifier is suitable for
speeds up to 133 rps
Software selectable: 0-5V, ±5V, 0-10V, ±10V
12 bits (with ±10V signal range)
11 bits (with 0-10V or ±5V signal range)
10 bits (with 0-5V signal range)
Software selectable from 200 to 51200 steps/rev in
increments of 2 steps/rev
Raises the system damping ratio to-0.3-0.5. eliminates
midrange instability and allows stable operation to 50 rps
Allows for fine adjustment of phase current waveform
harmonic content to reduce low-speed torque ripple in the
range 0.25 to 1.5 rps
Measures motor parameters and configures tuning and
observer parameters
Identifies the presence of an encoder and determines
resolution, diagnoses miswires and open phases
Software selectable from 200 to 51200 steps/rev in 2
steps/rev increments.
Software configurable filtering (4th order, elliptic) for use in
removing spectral components from the command sequence,
reduces jerk and excitation of extraneous system resonances
Employs encoder (hi or low resolution) to provide stall
detection, stall prevention and perform position verification
