Rexroth HMD01.1N-W0012-A-07-NNNN-AA Double-Axis Inverter R911326665

Product Overview

The Rexroth HMD01.1N-W0012-A-07-NNNN-AA is an HMD01 double-axis inverter power section for an IndraDrive M drive system. This inquiry listing identifies the full AA-suffix type code and material reference R911326665 for maintenance of installed machinery. The 12 A value identifies the peak-current class of the model. It is not a continuous-current rating and should not be used by itself to choose a spare. The complete designation, hardware index and configuration of both motor axes must be checked before an order is confirmed.

Two-Axis Power-Section Function

An HMD power section combines two motor power-output channels in one module. It receives energy from the drive system's DC bus and supplies the motor outputs as part of a configured two-axis installation. This is a power section rather than a complete standalone controller with its own mains supply. The shared supply arrangement, control hardware, firmware, motor feedback, brake connections and machine parameters determine the actual operation of the two axes. Identify these components when assessing an offered replacement unit.

DC Bus and Auxiliary Supply

The HMD01 operating instructions specify a DC power-input range of 254 to 750 V and a separate external 24 VDC auxiliary supply for the electronics. The auxiliary supply is not the motor power source. Confirm the permitted voltage range and the applicable supply tolerances against documentation for the actual hardware version, including requirements when motor holding brakes are supplied. Existing DC-link wiring and cabinet protection should be checked by qualified personnel using the machine's drawings; this listing does not propose a different electrical installation.

Cooling and Installation

The W configuration uses internal air cooling with forced ventilation. The condition and completeness of the fan assembly and the cabinet air path should be assessed for the actual unit. Observe the installation clearances and thermal requirements in the relevant operating instructions. Do not replace an air-cooled module on housing appearance alone or assume that a different cooling code has identical mounting requirements. Cooling performance also depends on cabinet conditions, contamination and the operating load of the installed axes.

AA Suffix and Material Reference

This page retains the complete NNNN-AA ending. The AA suffix is not omitted when searching or quoting, and the item is kept separate from a listing ending at NNNN. The associated public material reference is R911326665; verify that it appears with the correct full type designation on the offered unit's label. A related family code or a matching current class does not establish interchangeability between two catalog entries. Any permitted replacement relationship must be supported by the machine configuration and the applicable technical documentation.

Peak Current and Operating Duty

Peak output demand and continuous duty require separate assessment. Continuous current can vary with switching frequency, temperature and installation conditions, while the two motors may have different acceleration, torque and braking demands. Do not interpret the 12 A model class as an unconditional continuous capability or calculate an overall cabinet rating by simply adding two nominal values. Use the original axis sizing, motor data and operating duty to confirm that the actual power section is appropriate for the machine.

Control Hardware and Axis Configuration

The quotation should state whether the offered item is the bare HMD power section or includes installed control hardware. Communication interfaces, motor feedback support, parameter storage, operating panel and safety functions are not guaranteed by the power-section type code alone. Supply clear photographs of any fitted control-section label, the motor connectors and the complete nameplate. Identify the configuration for both axes and whether existing control hardware will be retained. Firmware and parameter backup requirements must be assessed before removal of the original assembly.

Condition and Supply Scope

The condition and completeness of the supplied spare are confirmed for each inquiry. New surplus, used or other disclosed conditions are stated in the quotation when an actual unit has been identified. Ask for available photographs showing the terminal area, fan components, covers and control hardware. Inspection or test evidence is supplied only when it exists for that unit. No manufacturer authorization, fixed inventory or unverified warranty is implied by this catalog entry. Accessories and connectors must be specified as included or excluded before the order is agreed.

MOQ, Availability and Dispatch

The minimum order quantity is 1 piece. The supply target is 10 pieces per month, subject to actual sourcing and availability. Confirmed in-stock units are normally dispatched within one week after the order and payment arrangements are completed. Non-stock sourcing and its lead time are agreed separately. Protective export packaging is arranged for the actual module and its connectors; shipping cost and packaging details depend on the destination and unit supplied. Final availability, condition and delivery terms are confirmed in the quotation.

Budget Price Basis

The displayed budget is USD 325.00 per piece, calculated as 65% of an observed eBay asking price of USD 500.00 for the related HMD01.1N-W0012-A-07-NNNN model. The reference does not carry the AA suffix and is used only as a pricing estimate for this HMD01.1N-W0012-A-07-NNNN-AA inquiry. It does not confirm an equivalent hardware revision, technical interchangeability or stock. The reference is an asking price, not a completed-sale record, and excludes shipping and taxes. The other seller's condition, testing, availability and warranty statements are not adopted as commitments for this listing.

Request a Matched Quotation

For a matched quotation, please send the full HMD01.1N-W0012-A-07-NNNN-AA type code, R911326665, a clear nameplate photograph, required quantity and delivery destination. Include the machine model, supply-unit code, installed control hardware and motor identifiers for both axes. A brief description of the failure or maintenance need helps define the required supply scope. Installation and commissioning should follow the machine builder's procedures, including parameter backup and applicable safety checks. Exact identification is reviewed before a final price and delivery date are offered.
