ASDA-A3
220V Models
The ambient temperature of the operating environment for the 220V servo drive is between 0°C
(32°F) and 55°C (131°F). If the temperature is over 45°C (113°F), place the product in a
well-ventilated environment. During long-term operation, the suggested temperature of the
operating environment should be under 45°C (113°F) to ensure the servo drive's performance.
Mount the product vertically in the distribution board (see the illustration of the correct mounting
direction in Section 2.3) and install a fan on the board for heat dissipation. Ensure that the
temperature for the clearance of 5 cm (1.97 inches) beneath and on both sides of the servo
drive is kept under 55°C (131°F), and the servo drive must be kept clear of heat sources.
Moreover, the airflow velocity at the measuring point which is 10 mm (0.4 inches) above the
servo drive of 400 W (or below) has to be greater than 0.5 m/s; the airflow velocity at the
measuring point which is 10 mm (0.4 inches) above the servo drive of 750 W (or above) has to
be greater than 1 m/s. Make sure the size of the distribution board and its ventilation condition
can prevent the internal electrical devices from overheating. Besides, check if the vibration of
the machine affects the electrical devices of the distribution board.
Measuring
point
I output (%) is the output current percentage;
Ta (°C) is the operating temperature
Note: the maximum operating temperature for the models of
750 W - 3 kW is up to 60°C (140°F), but the output
current declines as shown above; the maximum
operating temperature for the models of 400 W (or
below) and 4.5 kW (or above) is only up to 55°C (131°F).
