Maximum ambient temperature
50˚ C without derating.

Coated electronics
Improved reliability in corrosive and aggressive environments due to protection class 3C2 (EN 60721-3-3) as standard or optionally 3C3.

• Software features

Automatic Energy Optimization
The standard feature AEO provides optimized motor magnetization at all speeds and loads. This increases energy efficiency by 5-15% for partial loads.

LON for AKD, Modbus RTU. Enables fast and simple connections to overall controller.

Sleep mode
The drive detects when the load is too low and stops the motor. The load can e.g. be air flow or water pressure.

Day/night control
In day/night control mode the application runs normally during the day, while running with an increased set-point during night time.
