Technical FAQ & Operational Guide

Can this 11kW VFD run a 15HP motor?

Yes. This drive is rated for 11kW, which is equivalent to 15HP, making it a perfect match for 15HP 3-phase industrial motors.

Does the MS300 series support energy-saving functions?

Yes, it includes advanced algorithms that optimize motor efficiency under varying loads, which is particularly beneficial for reducing power costs in pump and compressor applications.

What safety certifications does this drive have?

The MS300 series includes integrated Safe Torque Off (STO) which complies with SIL2 and PLd safety standards, ensuring safe operation in industrial environments.

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.
