Mitsubishi Electric MELDAS MDS-B-SVJ2 Series - Servo Amplifier Generation Loss; Servo Amplifier Calorific Value

9-2 Servo amplifier generation loss
9-2-1 Servo amplifier calorific value
The servo amplifier calorific value is determined from the following table by the motor with which the
servo amplifier is combined. The calorific value for the actual machine will be a value between the
calorific values at the stall torque (at the rated torque) and the zero torque according to the frequency
during operation. Consider the worst usage conditions for the thermal design of the fully closed type
control panel, and use the values given below. Even when the servomotor is run below the maximum
speed, the servo amplifier calorific value will not change if the generated torque is the same.

(Note) The asterisk "*" in the motor type indicates the value for a combination with an amplifier having a one-rank lower capacity
than the standard.
POINT
1. The heat generated by the regeneration resistor is not included in the servo
amplifier calorific value. Refer to section "11-4 Selection of regenerative
resistor" and calculate the calorific value of the regenerative resistor using
the regeneration load and positioning frequency.
2. The area required for heat radiation is the heat radiation area (guideline) of
the fully closed type control panel storing the servo amplifier when using the
unit at an ambient temperature of 40°C and stall (rated) load.
