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)
Automatically calculates natural resonant frequencies and applies damping to the
control algorithm, greatly improving motor performance.
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 Measures motor parameters and congures tuning and observer parameters. At start-
up the drive measures motor parameters, including the resistance and inductance,
then uses this information to optimize system performance. The drive can also detect
open and short circuits.
MICROSTEP EMULATION Performs low resolution stepping by synthesizing ne microsteps from coarse steps.
COMMAND SIGNAL SMOOTHING Command Signal Smoothing can soften the effect of immediate changes in velocity
and direction, making the motion of the motor less jerky. An added advantage is that
it can reduce the wear on mechanical components.
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.
