Drive Watts Loss Data
The Open Chassis type drive can be installed in a fully-enclosed panel.
For installing the drive with capacity of
200 V class
22 kW or 400 V class 22 kW, be sure to leave
enough clearance during installation for
suspension brackets on both side of the unit and
main circuit wiring for maintenance.
Intake air temperature for external heatsink
Heatsink side:
50 ˚C
Open chassis side:
50 ˚C
Use only an open chassis type for the
external heatsink.
An open chassis model in a protective enclosure with the heatsink inside the panel allows for intake air temperature up to
50
˚C.
The heatsink can alternatively be mounted outside the control panel, thus reducing the amount of heat inside the panel and
allowing for a more compact set up.

Heat loss is calculated in the following conditions:
･
200 V class: Input voltage 220 V, power frequency 60 Hz, load ratio 100%
･
400 V class: Input voltage 440 V, power frequency 60 Hz, load ratio 100%
Contact your Yaskawa or nearest agent when not calculating heat loss in the above conditions.
