Technical Speciﬁcations

POWER AMPLIFIER SECTION

AMPLIFIER TYPE MOSFET , Dual H-Bridge, 4 Quadrant

CURRENT CONTROL 4 state PWM at 20 Khz

OUTPUT CURRENT STAC6 0.5— 6.0 amps in 0.01 amp increments (6A peak of sine)

STAC6-220 0.5— 3.2 amps in 0.01 amp increments (3.2A peak of sine)

POWER SUPPLY STAC6 Line Operated Nominal 120 VAC, 50/60 Hz

STAC6-220 Line Operated Nominal 220 VAC, 50/60 Hz

AC INPUT VOLTAGE STAC6 94—135VAC, 50/60Hz

STAC6-220 94—265VAC, 50/60Hz

PROTECTION Over-voltage, under-voltage, over-temp, external output shorts (phase to-phase, phase-to-

ground), internal amplier shorts

IDLE CURRENT REDUCTION Reduction to any integer percent of full-current after delay selectable in milliseconds.

MOTOR REGENERATION Built in regeneration circuit - 25watts max.

CONTROLLER SECTION

NON-VOLATILE STORAGE Congurations are saved in FLASH memory on board the DSP.

STEP AND DIRECTION INPUTS Optically Isolated: 5 Volt. Minimum pulse width = 200 ns. Maximum pulse frequency

= 2 MHz

RESOLUTION Software selectable from 200 to 51200 steps/rev in increments of 2 steps/rev

ANTI RESONANCE

(Electronic Damping)

Raises the system damping ratio to eliminate midrange instability and allow stable

operation throughout the speed range and improves settling time.

TORQUE RIPPLE SMOOTHING Allows for ne adjustment of phase current waveform harmonic content to reduce low-

speed torque ripple in the range 0.25 — 1.5 rps.

SELF TEST AND AUTO SETUP Checks internal & external power supply voltages, diagnoses open motor phases.

Measures motor parameters and congures motor current control and anti-resonance

gain settings.

MICROSTEP EMULATION Performs low resolution stepping by synthesizing ne microsteps from coarse steps.

COMMAND SIGNAL SMOOTHING Software congurable ltering reduces jerk and excitation of extraneous system

resonances (step & direction mode only)

ENCODER OPTION Employs encoder (hi or low resolution) to provide failsafe stall detect and perform stall

prevention and position maintenance. Differential line receivers suitable for 500 kHz

or greater. Minimum encoder resolution is 1000 lines.

INTERFACE RS-232 and RS-485 , CANopen standard on STAC6-C models.

AMBIENT TEMPERATURE 0 to 55

C (32- 158

HUMIDITY 90% non-condensing
