Installation

When installing an external regenerative resistor, connect the resistor to P3 and C contacts, and

P3 and D contacts are left open. It is recommended that you choose external regenerative

resistors of the resistance values specified in the table on the previous page. For easy

calculation of the required regenerative resistor capacity, regardless of the energy consumed by

IGBT, select the capacity of the external regenerative resistor according to the selected rotary

motor.

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.
