Technical FAQ & Operational Guide

Can this Delta VFD run a 1HP motor on single-phase power?

No, the 2A7MS43ANSAA model is specifically designed for a 3-phase 415V input. For single-phase input requirements, the MS300 series has dedicated 'single-phase to three-phase' models.

Does this VFD support Permanent Magnet (PM) motors?

Yes, the MS300 series is versatile and supports both standard Induction Motors (IM) and high-efficiency Permanent Magnet (PM) motors.

Is there a built-in safety function in the MS300?

Yes, it includes a built-in STO (Safe Torque Off) function, which is a critical safety feature for preventing the motor from starting unexpectedly during maintenance.

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.
