2.-5.2 Cooling
(1) Cooling system of drive unit
The drive has been designed so that it is able to work at the
environmental temperature 104°F (40°C) without any additional cooling fan.
The drive is cooled by a centralized cooling system a line blower. The air is
sucked in through the air vents on the front cover, passes through the air
fil ter and the line blower, and is blown uniformly over the entire DE, card
cage, power amplifier, and interface PCBs.
The air which passes through the card cage cools the DC power supply and
the air which passes over the DE cools interface PCBs, and is discharged.
