H-Bridge, 4 Quadrant
Current Control: 4 state PWM at 20 KHz
Output Current: 0.5 to 5.0 A/phase in
0.01 A increments
Power Supply: External 24 to 48 Vdc
power supply required
Input Voltage Range: 18 to 53 Vdc
Protection: Over voltage, under voltage,
over-temp, external output shorts
(phase-to-phase, phase-to-ground),
internal amplifier shorts
Idle Current Reduction: Reduction to
any integer percent of full-current after
delay selectable in milliseconds

-S AND -SI (COMMON FEATURES)
CONTROLLER SECTION
Mode of Operation: Step and direction,
CW/CCW, encoder following, oscillator,
joystick, SCL, Si (Si programming is
only available on the -Si models)
Microstep Resolution: Software
selectable from 200 to 51,200 steps/rev
in increments of 200 steps/rev
Speed Range: Depends upon selected
resolution; amplifier is suitable for
speeds up to 50 rps
Anti-Resonance: Raises the system
damping ratio to eliminate mid-range
instability and allows stable operation
to 50 rps
Waveform: 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
Dymanic Smoothing: Software
configurable filtering (4th order,
elliptic) for use in removing spectral
components from the command
sequence; reduces jerk and excitation
of extraneous system resonances
Encoder Option: Employs encoder
(high or low resolution) to provide stall
detection, stall prevention and perform
position verification and maintenance
