ASDA-B3 Installation 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 2 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.
(3) (1) (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.
