BRUSH MOTOR Enables the brushless motor option.
LINEAR DISPL This bit changes the display from degrees to inches (or millimeters) on the A
and B axes.
SCALE/X LO With SCALE/X HI bit, determines the scale factor used in bit SCALE FACT/X,
SCALE/X HI With SCALE/X LO bit, determines the scale factor used in bit SCALE FACT/X.

Parameter 2 X P GAIN
Proportional gain in servo loop.
Parameter 3 X D GAIN
Derivative gain in servo loop.
Parameter 4 X I GAIN
Integral gain in servo loop.
Parameter 5 X RATIO (STEPS/UNIT)
The number of steps of the encoder per unit of travel. Encoder steps
supply four times their line count per revolution. Thus a 2000 line en
coder and a 6mm pitch screw give:
2000 x 4 x 25.4 / 6 = 33867
Parameter 6 X MAX TRAVEL (STEPS)
Max negative direction of travel from machine zero in encoder steps.
Does not apply to A-axis. Thus a 20 inch travel and 2000 line encoder
and 6 mm pitch screw give:
20.0 x 33867 = 677340
Parameter 7 X ACCELERATION
Maximum acceleration of axis in steps per second per second.
Parameter 8 X MAX SPEED
Max speed for this axis in steps per second.
Parameter 9 X MAX ERROR
Max error allowed in servo loop before alarm is generated. Units are
encoder steps.
Parameter 10 X FUSE LEVEL
Fuse level in % of max power to motor. Applies only when motor in
motion.
