allowable duty ratio

! CAUTION
Service life may be shortened if the robot is used for longer than its allow-
able duty time.
For instance, if we set a job operation where work is gripped at point A, placed at
point B and then again returned to point A, all as one cycle taking place in 1
second, then the allowable duty is 70% which we calculate as:
Time needed for round-trip between A and B of 0.8 sec.
0.8 sec. for round-trip between A and B + 0.2 sec. for work transfer at points A&B
= 80%
Note that a time of at least 0.2 seconds is needed for stopping at points A and B.
