When installing an external regenerative resistor, connect the resistor to P and C contacts,
and P and D contacts are left open. It is recommended that you choose external regenerative
resistors of the resistance values specified in the table on page 16. Choose the external
regenerative resistor according to the selected rotary motor (the setting value has included the
factor of energy consumed by the IGBT).
Rotary motor:
Selecting the regenerative energy
(a)
Calculation of the regenerative energy when there is no external torque.

(2)
(1) Moving direction of the object; (2) Direction of torque;
(3) Regenerative energy generated when the motor decelerates
If the motor is making a reciprocating motion, the regenerative resistor consumes the excess
return energy. Refer to the following table when calculating and selecting the required
regenerative resistor.
