Power Supply Capacity And Generated Loss - Mitsubishi Electric MR-J4-TM Instruction Manual

14. USING A LINEAR SERVO MOTOR

14.4.2 Power supply capacity and generated loss

Table 14.1 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.

Note 1. Note that the power supply capacity will vary according to 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 section 11.2.
