6.16.8 PTP Speed / Acceleration for Small Distances
You can change the speed and acceleration for small distances using PTPBoost and
PTPBoostOK. Normally, PTPBoost is not required. In certain cases, you may want to
shorten the cycle time even if vibration becomes larger, or conversely you may want to
reduce vibration even if cycle time becomes longer. PTPBoost is a robot parameter with
values from 0 – 100 that affects the speed and acceleration for small distances. Normally,
for small distance motion, the desired speed cannot be attained using the current
acceleration. By increasing PTPBoost, acceralation, deceleration, and speed are increased
for small distance motion. To check if a motion command will be affected by PTPBoost,
use the PTPBoostOK function. See PTPBoost and PTPBoostOK in the SPEL+ Language
Reference manual for more details.
