Altitude Derating

Install the drive in a location that has an altitude of 1000 m (3281 ft) or lower.
Derate the output current by 1% for each 100 m (328 ft) to install the drive in altitudes between 1000 to 4000 m (3281
to 13123 ft).
It is not necessary to derate the rated voltage in these conditions:
• Installing the drive at 2000 m (6562 ft) or lower
• Installing the drive between 2000 to 4000 m (6562 to 13123 ft) and grounding the neutral point on the power
supply.
If you do not ground the drive with a neutral network, contact Yaskawa or your nearest sales representative.
