Servo Amplifier Capacity of 0.5 to 5.0kW
Servomotors with a capacity of 500W to 5kW have built-in regenerative resistors.
The allowable frequencies for just the servomotor during acceleration/deceleration
operation, in the run cycle from 0 to 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.
Servo Amplifier Capacity of 6.0kW or More
Servomotors with a capacity of 6.0kW or more do not have built-in
regenerative resistors. The following table summarizes the allowable frequencies
for the servomotor during regeneration mode, when the servo amplifier is combined
with the JUSP-RA04 or JUSP-RA05 Regenerative Resistor Unit.
