Power Supply Equipment Capacity And Generated Loss - Mitsubishi Electric MELSERVO MR-J2S- A Instruction Manual

12. CHARACTERISTICS

12.2 Power supply equipment capacity and generated loss

(1) Amount of heat generated by the servo amplifier
Table 12.1 indicates servo amplifiers' power supply capacities and losses generated under rated load.
For thermal design of an enclosure, use the values in Table 12.1 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, use Equation 13.1 in Section 13.1.1.
