■The maximum loads refer to<br />
50 Hz. Please inquire about<br />
60 Hz operation.<br />
* Bracketed values with frame sizes<br />
112 to 160 apply to 1MJ6 motors.<br />
The figures for the maximum axial<br />
loads have been calculated<br />
assuming the maximum permitted<br />
cantilever forces.<br />
Please ask for advice if the loading<br />
direction alternates (i.e. if<br />
the side from which the load is<br />
applied changes).<br />
