Bumper Stops
In addition to software overtravel limits and limit sensors the end of travel
bumper stops can stop the slide up to the ratings listed. Bumper stops are not
intended to be used as range of motion stops.
Table 4 - Bumper Stop Energy Limits for Stage End of Travel
To calculate kinetic energy of the slide with your payload use the formula
J in jules
M = moving mass in kg (slide + payload)
V = maximum velocity of stage in your application in m/s
(1)
Cat. No. Bumper Stop Energy Limit
CHPS-x6xxxx-xLMxxx 37.3 J (330 in•lb)
CHPS-x8xxxx-xLMxxx 45.5 J (403 in•lb)
CHPS-x9xxxx-xLMxxx 35.2 J (312 in•lb)
ATTENTION: If energy greater than the bumper capacity is anticipated in the
application, provide additional mechanical means for safely stopping the slide.

(1) Velocity and kinetic energy can be much higher due to a uncontrolled worst-case motion constrained by the stroke and power
capacity of the motor drive pairing only.
