CHAPTER 4 Adjustment
(2) Setting the Z-axis soft limits
Make this setting from outside the safeguard enclosure.
The Z-axis has mechanical stoppers fixed at the upper and lower ends of
the Z-axis movement range. When the actual working range of the robot is
smaller than the maximum working envelope or the manipulator interferes
with the peripheral equipment, reduce the Z-axis plus (+) soft limit [pulses]
to narrow the working envelope.
(3) Setting the R-axis soft limit
To make this setting, set emergency stop just as for the X-axis and Y-axis,
or be sure to do this from outside the safeguard enclosure. The R-axis has
no mechanical stoppers. When the actual working range of the R-axis is
small or it interferes with the peripheral equipment, reduce the R axis plus
(+) soft limit [pulse] and minus (-) soft limit [pulses] to narrow the working
envelope.
(4) Relation between the X, Y and R-axis movement angle, the Z-axis move-
ment distance and the number of pulses
The tables below are for calculating resolver pulses with respect to the X, Y
and R-axis movement angles and to the Z-axis movement distance for each
robot. Use these figures as a guide to set the soft limits.

CAUTION
OVERLOADS MAY OCCUR IF THE SOFT LIMIT IS ALMOST NEAR THE
ENCODER PULSE AT THE MECHANICAL STOPPER AND THE
OPERATING POINT IS USED AT THE EDGE OF THE MOVEMENT RANGE.
SET THE SOFT LIMIT TO THE INNER SIDE OF THE MECHANICAL
STOPPER WITH AN AMPLE SAFETY MARGIN.
