Servo Amplifier Capacity of 0.8 to 3.0kW
Servomotors with a capacity of 500W to 3kW have built-in regenerative
resistors. The allowable frequencies for just the servomotor during
acceleration/deceleration operation, in the run cycle from 0 to the
maximum rotation speed to 0, are summarized in the following table.
Convert the data into the values obtained with actual rotation speed
used and load inertia to determine whether an external regenerative
resistor is needed.
