FAQs

Q1: What is the difference between an open-loop and closed-loop system drive?

A1: Open-loop drives control motor speed without feedback, while closed-loop drives use a feedback loop to adjust the output based on actual motor behavior. Closed-loop drives provide more precise control and are better suited for demanding applications.

Q2: How do I calculate the appropriate drive size for my application?

A2: Refer to the motor manufacturer's specifications for the required power, torque, and speed. Select a drive with a power rating slightly higher than the motor's rated power to account for potential overloads.

Q3: What is the warranty period for ABB system drives?

A3: ABB system drives typically come with a standard warranty period of 2 years. Extended warranty options are available for added peace of mind.
