2.6.2 When a Separated Regenerative Discharge Resistor is Needed by
SVM1-4 i and SVM1-20 i.
If the amount of energy regenerated per regeneration cycle exceeds the
maximum amount of energy that a servo amplifier can handle, a DC link
over-voltage alarm occurs. In this case, a separated regenerative
discharge resistor is needed.
Note in mind that an incorrect connection can damage the
amplifier.
Selecting a regenerative discharge resistor
First obtain how much regenerative energy occurs.

  • Page 776 HEAT DISSIPATION The amount of heat dissipation depends on the SVM model and the current that flows through the servo motor. For the current that flows through a servo motor, reference the continuous rated current of each servo motor. (For the continuous rated current of each servo motor, refer to
  • Page 78(2) Residual amount of heat in the cabinet By placing the heat sink section outside the cabinet, the residual amount of heat in the cabinet can be calculated according to the expression below. Residual amount of heat in the cabinet = a + Kb1 × b1 a: Amount of heat dissipation determined by the SVM m
