Frequently Asked Questions (FAQ)

What applications benefit most from this 2 HP high-performance drive?

It is ideal for precision applications requiring advanced control, such as small machine tool spindles, positioning systems, test benches, and automated equipment where precise speed/torque regulation and connectivity are critical.

What is the benefit of the wide carrier frequency range (1-16 kHz)?

It allows fine-tuning of motor performance. Lower frequencies reduce switching losses, while higher frequencies minimize motor audible noise and improve the smoothness of vector control at low speeds.

Does it include a braking resistor?

No, the drive has an integrated dynamic braking chopper circuit. An external braking resistor must be supplied and connected by the user based on the application's braking energy requirements.

How does the dual Ethernet port functionality help?

Dual ports enable easy daisy-chaining of multiple drives without needing an external Ethernet switch, simplifying network topology and reducing installation costs.

What is required to use the Safe Torque Off (STO) feature?

STO requires connection to a safety-rated control device (e.g., safety relay, PLC) via the designated terminals. Implementation must follow all applicable safety standards and validation procedures.
