NOTE:
1. Output*: Default is heavy duty.
2. IP40*: The IP ratings of the wiring area (main circuit terminals and control terminals for frame A/B/C/D/E/F)
and the vent near the capacitor (frame C/D/E/F) are both IP20.
3. The value of the carrier frequency is a factory default. Decrease the current value if you need to increase the
carrier frequency. Refer to Section 9-7 Derating for Ambient Temperature and Altitude for details.
4. For shock or impact load applications, select a drive with a larger capacity model.
