Calculation of inverter acceleration and deceleration time
I am planning to control rotation of a centrifuge, but I wonder how long it takes for acceleration. Let me know how to calculate it.
The conditions given by the centrifuge manufacturer are as follows:
- Motor: SF-JRV 15 kW 6P 200 V
- Total inertia upon startup and braking (based on motor shaft): 40 kgm2
- Mechanical loss (resistance torque): Approximately 25% of motor output
Calculate the acceleration time upon startup from "rated torque - resistance torque" of the motor
Calculate the deceleration time upon braking from the "rated torque" of the motor.
Can you calculate the acceleration time under these conditions? Do you have any calculation reference?
(Such as selection sample contained in the Servo Motor Instructions Manual)
Assume that the inverter is A520.
