Series overview
What MDD021 identifies
MDD021 includes the MDD021A and MDD021B models. The compact frame does not make the lengths interchangeable; preserve the complete winding, feedback, shaft and connection configuration from the tag.
Ratings, connections, feedback, braking and mechanical options vary by complete type code. Send Litco Automation a clear nameplate photo so the exact configuration and compatible replacement can be confirmed.

Series questions
MDD021 questions
Before Litco pulls a unit
Is MDD021 enough information to order a replacement?+
No. MDD021 identifies the series group, but the complete type code still carries the winding, cooling, feedback, mounting, shaft, brake and mechanical options that determine compatibility.
Which MDD021 fields should I compare first?+
Start with complete mdd type code and motor-length letter; nominal-speed or winding code; cooling and housing design. Then preserve the remaining suffix, material number, revision and every installed option or firmware label.
Where is MDD021 equipment commonly used?+
MDD021 is documented for digital machine-tool axes, printing and packaging equipment, robotics and handling systems, high-precision production machinery. The installed machine, axis and connected equipment still control the final replacement decision.
Can Litco evaluate a failed MDD021 unit?+
Yes. Litco can discuss replacement, repair and exchange paths after reviewing the complete code, application and failure information.
