Delta VFD MS300 2.2kW 3HP 1-Phase to 3-Phase AC Drive - 11AMS21ANSAA

The Delta VFD MS300 (11AMS21ANSAA) is a robust and highly efficient compact vector control drive designed to deliver heavy-duty performance from a single-phase power source. This 2.2kW (3HP) unit is the ideal solution for workshops and industrial settings where only 230V single-phase power is available but 3-phase motor performance is required. It features advanced motor control logic for both Induction Motors (IM) and Permanent Magnet (PM) motors, ensuring precise speed and torque regulation. With built-in STO (Safe Torque Off) safety features, an integrated PLC for custom logic, and a high-speed USB port for rapid commissioning, the MS300 optimizes efficiency in CNC routers, heavy-duty conveyors, industrial fans, and pumping systems.

Technical FAQ & Operational Guide

Can I use this 2.2kW VFD for a 2HP motor?

Yes. This VFD is rated for up to 3HP (2.2kW). Using it for a 2HP motor provides extra headroom and safety margin, though you must configure the motor parameters correctly in the VFD.

How do I wire a 3-phase 415V motor to this 230V VFD?

You must check if your motor can be wired in 'Delta' for 230V operation. This VFD outputs 3-phase 230V. Most standard industrial motors are 415V Star / 230V Delta; ensure the motor terminals are linked correctly.

What protection features does this Delta drive have?

The MS300 includes comprehensive protection against overvoltage, overcurrent, undervoltage, overheating, and motor overload, alongside a built-in safety STO function.

How is the rotational balancing calibrated on this spindle motor?

Every spindle motor is dynamically balanced in accordance with the ISO 1940 balancing standard to guarantee vibration-free running and maximum stability at high RPMs.

What are the runout tolerances of the shaft and collet interface?

The internal shaft taper maintains a runout accuracy tolerance of under 0.003mm (3 microns), maintaining precise tool concentricity and preventing premature cutter wear.

What cooling precautions are built-in to prevent heat exhaustion?

Built-in temperature dissipation channels support continuous water/liquid cooling circulation or forced fan airflow, preventing thermal expansion of components.

Is this spindle motor compatible with standard VFD inverters and collets?

Yes, the spindle supports direct electrical integration with standard variable frequency drives (VFD) and accepts industrial ER collets (ER11, ER20, ER25, or ER32) to match standard toolholder dimensions.
