Power Supply Capacity And Generated Loss [Wg] - Mitsubishi Electric MELSERVO-J5 User Manual

Power supply capacity and generated loss [WG]

Calculate the generated loss and the power supply capacity of the servo amplifier under rated load by referring to this section.
The calculated value will vary depending on the number of connected linear servo motors and the capacities of the linear
servo motors. For thermal design of an enclosed type cabinet, use the values calculated in consideration for the worst
operating conditions. The actual amount of generated heat depends on the frequency of operation and will be between the "At
rated output" and "At servo-off" values. When the linear servo motor is run at less than the rated speed, the power supply
capacity will be smaller than the calculated value, but the servo amplifier's generated heat will not change.
Calculation method of power supply capacity
Calculate the power supply capacity for one servo amplifier from the following tables.

*1 The power supply capacity will vary according to the power impedance. This value is applicable when the power factor improving reactor
is not used.
