Number of connectable regenerative resistor units (Option) (Reference)
Shown below is a reference of the number of regenerative resistor units (option) connectable.
For instance, if the total motor wattage of ELECYLINDER units is 800 W in horizontal orientation
and 400 W for the total in vertical orientation, take 800 W in Horizontal and 400 W in Vertical, find
the crossing point and you will see that the number of regenerative resistor unit you will need is
two units (reference).

[Caution]
1. The values shown in the table above is a reference assuming that an actuator is ran back and
forth under the condition of rated acceleration/deceleration, rated load, 1000 mm stroke and
duty ratio at 50%.
2. Regenerative energy is absorbed also inside the controller. In case it exceeds the capacity,
the excess assumed regenerative electric discharge alarm should be generated. In such a
case, add a regenerative resistor unit externally.
In case the duty ratio of an operation is higher than 50% or the load in the vertical oriented
installation is large, it is necessary to have more regenerative resistor units than shown in the
table above.
The maximum number of regenerative resistor units connectable should be five units.
Do not attempt to connect more than five units as it could cause malfunction.
3. If you would require to find out the optimum number considering your operation condition, use
the calculation software to figure it out.
