Electromagnetic compatibility
An EMC mounting plate is supplied with the drive controller for grounding the shields of the power cables when the installation must
meet EN 55011 Class A requirements. Refer to “Electromagnetic Compatibility” in the Altivar® 31 Installation Manual, bulletin
number VVDED303041US, for instructions on securing the mounting plate and grounding the cable shields on the EMC plate.
Derating curves
The derating curves below show the drive current (In) as a function of
temperature, switching frequency, and mounting type. For intermediate
temperatures, such as 55 °C (131 °F), interpolate between two curves.
ATV31 drive controllers can be used at altitudes up to 3,300 ft (1,000 m)
without derating. Derate by 1% for each additional 330 ft (100 m).
