Power Supply Capacity And Generated Loss - Mitsubishi Electric MELSERVO-J4 Series Instruction Manual

10.2

Power supply capacity and generated loss

Amount of heat generated by the servo amplifier
The following table indicates servo amplifiers' power supply capacities and losses generated under rated load. For thermal
design of an enclosed type cabinet, use the values in the table in consideration for the worst operating conditions. The actual
amount of generated heat will be intermediate between values at rated torque and servo-off according to the duty used during
operation. When the servo motor is run at less than the rated speed, the power supply capacity will be smaller than the value
in the table, but the servo amplifier's generated heat will not change.
