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

Power supply capacity and generated loss

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 linear 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.
Mounting a heat sink outside of the cabinet enables to reduce heat in the cabinet and design a compact enclosed type
cabinet.

*1 The power supply equipment capacity changes with the power supply impedance. This value is applicable when the power factor
improving AC reactor or power factor improving DC reactor are not used.
*2 Heat generated during regeneration is not included in the servo amplifier-generated heat. To calculate heat generated by the
regenerative option, refer to the following.
