Motion Control Functions
• Programmable step rates from 20 steps/sec to over 27,000 steps/sec provide extremely
large dynamic range.
• Linear acceleration curves for optimum performance.
• Partial accelerations make short moves in the least time.
• Separate parameters for starting rate, final rate, and acceleration values allow totally
programmable motions.
• Relative moves of +/- 16 Mega steps from current position. Absolute moves within a 16
Mega step range.
• Continuous moves with no specific number of steps, allow acceleration from the starting
rate to the final rate, followed by an indefinite run length.
• Internal step position updated during all motions.
Motor Support Signals
• Step Pulse and Direction signals
work with standard power driver
modules.
• Internal or external direction
control.
• Forced ramp down and abort
signal for emergency or externally
controlled end of motion.
• Separate CW and CCW limit
signals inhibit stepping beyond
one limit, but allow stepping in the
opposite direction.
• Moving/not moving signal for use
as Motion Complete or to switch
stepper power driver between
high and park power.
• Externally operated jog mode,
with direction control and
start/stop control from one signal,
all at programmable manual
control step rates between 1 and
1K steps/sec.
• Automatic home sensor seek,
with backlash compensation.
