(6) Load on the Actuator
Table below shows the allowable load moment and allowable load overhang length for each actuator.
Use the actuators within the allowable range.

Caution : Do not have the load mounted on the actuator exceed the allowable load overhang
length (L). If it is exceeded, it may cause an occurrence of vibration or longer
operation time.
Using the actuator with the moment greater than the allowable load moment applied
may not only shorten the guide life, but also cause an occurrence of vibration or
longer operation time.
: When using the axes cantilevered and X-Y combined, base body of the Y-axis has a
risk to get deformed. Use under the condition of Ma and Mc moments less that 1/2 of
the rated values.

Have the Ma and Mc moments
placed on this slider less than
1/2 of the rated.
The picture above shows IS(P)A-W as an example, however, also handle in the same manner for
other actuators.
