Power Supply Equipment Capacity And Generated Loss - Mitsubishi Electric MR-J3-10B Instruction Manual

10. CHARACTERISTICS

10.2 Power supply equipment capacity and generated loss

(1) Amount of heat generated by the servo amplifier
Table 10.1 indicates servo amplifiers' power supply capacities and losses generated under rated load. For
thermal design of an enclosure, use the values in Table 10.1 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
maximum speed, the power supply capacity will be smaller than the value in the table, but the servo
amplifier's generated heat will not change.

Note 1. Note that the power supply capacity will vary according to the power supply impedance. This value assumes that the power
factor improving reactor is not used.
2. Heat generated during regeneration is not included in the servo amplifier-generated heat. To calculate heat generated by the
regenerative brake option, in Section 11.2.
