Product description

What to know about HMS02.1N-W0028-A-07-NNNN

The HMS02.1N-W0028-A-07-NNNN is an IndraDrive M single-axis inverter. It takes power from the shared DC bus and produces the controlled three-phase output for one servo motor axis.

Bosch Rexroth project-planning data identifies the 0028 current class, internal blower cooling, IP20 protection and the 07 DC-bus class. Published cross-reference records associate the unit with material number R911309078.

A complete drive also depends on the installed control section and firmware. Include those labels with the HMS nameplate when asking Litco for a replacement or repair.
