Negative torque: TL × Wr TL: external load torque
For safety reasons, please calculate it by considering the safest situation.
For example, when the external load torque is the +70% rated torque and the rotation
reaches 3000 r/min, then take 400 W (the rated torque is 1.27 Nt-m) as the example,
the user has to connect the regenerative resistor of 40, which is 2 × (0.7× 1.27) ×
(3000 × 2 × π／60) = 560W.
(2) Simple Selection
Choose the appropriate regenerative resistor according to the allowable frequency
and empty load frequency in actual operation. The so-called empty allowable
frequency is the frequency of continuous operation when the servo motor runs from
0r/min to the rated speed and then decelerates from the rated speed to 0r/min within
the shortest time. The following table lists the allowable frequency when the servo
drive runs without load (times/min).
