Delta VFD MS300 1.5kW 2HP 1-Phase to 3-Phase AC Drive - 7A5MS21ANSAA

The Delta VFD MS300 (7A5MS21ANSAA) is a high-performance compact vector control drive designed to bridge the gap between single-phase power supply and three-phase motor requirements. This 1.5kW (2HP) unit is specifically engineered to optimize the operation of CNC routers, pumps, and conveyors in environments where only 230V single-phase power is available. It supports both Induction Motors (IM) and Permanent Magnet (PM) motors, providing incredible flexibility for industrial automation. With built-in PLC functionality, a high-speed USB port for configuration, and an integrated STO (Safe Torque Off) safety feature, the MS300 ensures smooth motor performance, high torque at low speeds, and superior energy efficiency.

Technical FAQ & Operational Guide

Can I use this VFD to run a 3-phase 415V motor?

No. This VFD takes 1-phase 230V input and outputs 3-phase 230V. You must ensure your motor is configured (usually via Delta/Star connection) to run on 230V 3-phase.

What is the maximum frequency output of the MS300 series?

Standard MS300 models like the 7A5MS21ANSAA support an output frequency up to 599 Hz, which is ideal for high-speed CNC spindles.

Does this VFD have built-in safety features?

Yes, it includes an integrated STO (Safe Torque Off) function, which complies with international safety standards to prevent the motor from accidental restarts.

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.
