2.3.5 Connection of Regenerative Resistance Unit
Connect the regenerative resistance unit with a cable enclosed with it referring to the figure
below. The cable to connect with MSCON and that to connect each regenerative resistance
unit differ to each other in the model code.

Caution : The number of connectable units is a reference for when operation is made
under the following condition;
[Condition] When 1,000mm of back and forth operation is made under the
actuator maximum speed, acceleration/deceleration 0.3G and
rated load with the duty 50%.
In some operational conditions, gateway alarm “0A2 Motor Power Voltage
Error” or “0AB Estimated Regenerative Discharge Power Excess” may be
generated, and it may require more regenerative resistor that described in
the table above. In such cases, add more regenerative resistance units.
However, please note the number of maximum connectable regenerative
resistance units is 4. It is not effective even with connection more than
necessary. Consider to change the operational conditions (to reduce the
load) or to use a higher specification actuator.
