Number of Connectable Regenerative Resistor Units (Reference)
Shown below is a reference for the number of the regenerative resistor units connectable to the DC power supply for motor drive (PSA-200).
When the total motor wattage of ELECYLINDER in horizontal orientation is 800W and the total in vertical orientation is 400W for example, the value where 800W in horizontal and 400W in vertical crosses shows that the regenerative resistor units should be two units (reference).
Refer to Regenerative Resistor Unit (Option) for the specifications of the regenerative resistor unit.

* Value in brackets in the table indicate shows the number of connected units when using including S18/S18X (600W/750W motor equipped models).
Caution
- The table above shows a reference when an ELECYLINDER makes a back and forth operation under the condition of rated acceleration/deceleration, rated load, stroke at 1,000mm and 50% of duty ratio.
- Regenerative energy should be absorbed also in a controller. When it exceeds the allowance range, “Estimated Regenerative Discharge Power Excess Alarm” should get generated. In such a case, connect an additional regenerative resistor unit externally.
- If the duty ratio of operation is higher than 50% or load is high in vertical orientation, it is necessary to have more regenerative resistor units to be connected than what is shown in the able above.
Also, the number of connectable regenerative resistor units should be five at the maximum.
Connecting more than five units may cause malfunction. Make sure not to do so.
