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