Power Amperage and Heat Radiation
For the power amperage and heat radiation on each axis, use the values shown in the table and figure out in the formulas below.
Figure out the power amperage and heat radiation for the axes connected to the DC power supply for motor drive.
The total should be the power amperage and heat radiation of the DC power supply for motor drive.
Figure out the power amperage and heat radiation for the axes connected to the DC power supply for motor drive.
The total should be the power amperage and heat radiation of the DC power supply for motor drive.
Rated power amperage [VA] = Motor power amperage [VA] + Control transient max. power amperage [VA]
Transient max. power amperage [VA] = Motor transient max. power amperage [VA] + Control transient max. power amperage [VA]
Heat radiation [W] = Motor power supply heat radiation [W] + Control power supply heat radiation [W] + Fixed resistor heat radiation [W]
Transient max. power amperage [VA] = Motor transient max. power amperage [VA] + Control transient max. power amperage [VA]
Heat radiation [W] = Motor power supply heat radiation [W] + Control power supply heat radiation [W] + Fixed resistor heat radiation [W]

(Note) The control power supply shows the values at the maximum load.
(Note) The values for the motor power supply may differ depending on load. It shows the maximum performance of the controller.
(Note) Current up to three times of the rated current at the maximum should flow during acceleration. Therefore, the transient maximum power amperage should be three times of the power amperage.
