Frequently Asked Questions

What is the difference between the heavy duty and normal duty ratings?

In heavy duty (HD) mode, the ATV340D11N4 is rated for 11 kW / 24 A at 4 kHz with higher overload capacity, suitable for demanding loads such as conveyors. In normal duty (ND) mode, it is rated for 15 kW / 32 A, optimized for variable-torque loads like pumps and fans.

What supply voltage is required?

The drive accepts 3-phase 380 to 480 V AC with a tolerance of –15 % to +10 %, covering standard 400 V and 480 V industrial supplies.

Is the ATV340D11N4 suitable for functional safety applications?

Yes. The drive is certified to IEC 61508 and ISO 13849-1, supporting safety functions such as STO (Safe Torque Off) for integration into safety-related control systems.

What mounting arrangement does this drive require?

The ATV340D11N4 is designed for cabinet mounting with dimensions of 180 mm (W) × 385 mm (H) × 249 mm (D) and weighs 9.5 kg.
