When using an external regenerative resistor, the resistor should connect to P3, C terminal; and
the contact of P3, D terminal should be left open. It is recommended that you choose the above
mentioned resistance. For easy calculation of the regenerative resistor capacity, except for the
energy consumed by IGBT, there are two ways provided to calculate the capacity according to
the selected linear motor or rotary motor.
Rotary Motor:
(a) Calculation of the regenerative power when there is no external torque
(1) Direction of motion of the object; (2) Force direction of the motor;
(3) Regenerative power generated while the motor decelerates
If the motor is making a reciprocating motion, the regenerative resistor consumes the spare
energy. You can select the regenerative resistor by calculating the regenerative power. Refer to
the following table when calculating and selecting the required regenerative resistor.
