The INDRAMAT HMS01.1N-W0070-A-07-NNNN, material number R911295326, is a power supply module from the IndraDrive M family, designed for multi-axis servo systems used in CNC machines and industrial automation. It provides the shared DC link power required by connected IndraDrive M power sections and servo axes.

The module is installed in the CNC control cabinet and supplies stable DC bus voltage to multiple servo drives operating with Rexroth servo motors. This shared power architecture is suitable for applications requiring coordinated multi-axis motion, including CNC machine tools, automated production lines, packaging equipment and material-handling systems.

The unit is specified as a single-axis servo drive module with a 42.4/49 A current rating, 254 VDC and 500/750 VAC input specifications, with an operating frequency range up to 1000 Hz according to the supplied product data.

The exact reference HMS01.1N-W0070-A-07-NNNN / R911295326 is important when sourcing a replacement, as the complete designation determines the required electrical and mechanical configuration. It is therefore recommended to match the original nameplate and all suffixes before installation.

This INDRAMAT module is suitable as a replacement unit, spare part or CNC replacement component for existing IndraDrive M installations. A tested unit can be checked for DC bus behavior, communication and status signals before dispatch, providing a practical solution for maintenance, retrofit and emergency replacement on legacy CNC equipment.

Frequently asked questions about HMS01.1N-W0070-A-07:

What IndraDrive platform does this unit support
It is part of the Rexroth IndraDrive M modular system and supplies the DC bus for multi-axis power sections within that platform.

How do I confirm drop-in compatibility for a field replacement
Match the complete code on your installed nameplate including all suffixes and the R911295326 material number. This ensures electrical rating and connection layout align with your cabinet.

Does this supply require parameter setup after installation
In most cabinets the supply module is plug-in while axis parameters reside in the associated drive controllers. Use the original configuration and wiring to maintain the same operating conditions.

Can this unit be used as a stocked spare for preventive maintenance
Yes, many MRO teams keep a stocked spare to shorten downtime when a supply fault occurs. Verify the rating code W0070 matches the original design capacity before planning the swap.
