Fig 7.8 Operation Pattern Of Vertical Load - OE Max Controls CSDJ Plus User Manual

The table above is for the horizontal load. When using in
vertical load, allowable load inertia may be lowered
according to the usage conditionRefer to [C. Vertical Load].
The table above is load inertia when operating in rated
speed. Supposing that there is no friction, energy the rotor
generates is calculated as follows
Thus, when operating above the maximum speed, the
maximum allowable load inertia is remarkably lowered.
Contact the agencies. On the contrary, if it is operated with
lower than rated speed, it can correspond to greater load
inertia than that of above table. In other words, if the speed
is reduced to half, then the allowable load inertia gets 4
times bigger.
Vertical Load
In case of vertical load operation, continuous regeneration area
may occur when moving downward at a constant speed. Be cautious
in regeneration when operating a vertical load. Motor speed or torque
value can be checked in DA output (CN1 pin 23, 28) or PC S/W.
