Installation & Setup Guide

1. Ensure the power source matches the 320-528VAC or 460-740VDC range.

2. Mount the inverter securely using its compact dimensions (78x350x250mm).

3. Connect the 3-phase mains wiring according to local regulations.

4. Wire your servo motor to the output terminals.

5. Configure the rated voltage (400V or 480V) and switching frequency (8 or 16 kHz) for your application.

Compatibility Information

The EVS9322-ES is designed to control standard 4-pole asynchronous servo motors (ASM) up to 0.75 kW. It is perfectly suited for integration into automation systems requiring precise speed and torque control, such as conveyors, packaging machines, and material handling equipment.

Professional FAQs

Q: What is the main benefit of the dual voltage rating?

A: It provides great flexibility. You can install the same inverter unit in different factories or regions that use either 400V or 480V standard mains power without needing a different model.

Q: When should I use the 8 kHz vs. the 16 kHz switching frequency?

A: Use 8 kHz for higher output current and torque. Choose 16 kHz for smoother motor operation and reduced audible noise, accepting a slightly lower current rating.

Q: Can I power this drive from a DC bus?

A: Yes. The unit can connect directly to a 460-740 VDC supply, making it ideal for systems with a common DC bus or battery backup.

Q: Is this drive suitable for a basic pump or fan?

A> While it can work, this is a high-performance servo inverter designed for dynamic motion control. For simple pumps/fans, a standard variable frequency drive (VFD) is often more cost-effective.

Q: How do I choose between the rated current and the maximum current?

A: The rated current (e.g., 2.5A @8kHz) is for continuous, safe operation. The maximum current (e.g., 5.0A) is for short-term peaks during acceleration or overload. Size your motor accordingly.
