Description
Product Overview
The Bosch Rexroth HCS01.1E-W0018-A-03-B-ET-EC-PB-NN-NN-FW is part of the IndraDrive Cs family, which integrates the power stage and control electronics into a compact drive unit for single-axis motion applications. It is intended for applications where a servo motor must be controlled through a configured motion-control system, such as packaging equipment, assembly machinery, and automated production lines. The drive’s 18 A maximum-current rating is a peak rating, not a continuous-current rating; thermal conditions, switching frequency, and duty cycle affect the usable output.
The communication configuration is a key selection criterion. The ET code is associated with MultiEthernet communication, while PB identifies the PROFIBUS interface option. The EC code identifies the configured multi-encoder interface, with supported encoder types depending on the drive configuration. These features do not mean that every industrial Ethernet protocol or every encoder can be used without configuration checks. Confirm the required fieldbus, controller compatibility, encoder feedback type, and drive firmware before installation.
The model is specified for three-phase AC input from 200 to 500 V, with integrated forced-air cooling and an IP20 enclosure. That enclosure rating is intended for protected cabinet installation, not direct exposure to dust or water. Published data lists 7 A continuous current and 18 A maximum current, with firmware needing separate selection or confirmation. During procurement, check the complete order number, existing motor and feedback arrangement, firmware identification, and any installed safety functions. Do not assume that a visually similar HCS01 drive has the same interface or safety configuration.
Product Introduction
The HCS01.1E-W0018-A-03-B-ET-EC-PB-NN-NN-FW is designed for compact, single-axis servo control where the application requires an 18 A peak-current drive, MultiEthernet communication, and a PROFIBUS interface option. Its multi-encoder capability allows connection to supported motor feedback systems when the encoder and drive configuration are correctly matched.
For a replacement installation, verify the motor’s rated current and voltage, encoder type, control-system fieldbus, firmware, and parameter backup. Also confirm cabinet ventilation and the drive’s permitted operating environment. The complete type code matters: a different option code can change the available interface or safety functionality.

Frequently Asked Questions
Q1: What is the .1E-W0018-A-03-B-ET-EC-PB-NN-NN-FW?
It is a Bosch Rexroth IndraDrive Cs compact single-axis drive controller with an 18 A peak-current rating, MultiEthernet communication, a multi-encoder interface, and a PROFIBUS option.
Q2: What is the difference between its peak and continuous current ratings?
The published peak rating is 18 A, while the listed continuous rating is 7 A. Peak current is intended for limited operating conditions; continuous output depends on thermal conditions, switching frequency, and application duty cycle.
Q3: Does this drive support PROFIBUS and Ethernet?
Its type code identifies MultiEthernet communication and a PROFIBUS option. Confirm which interface the machine uses and how it is configured before ordering or commissioning.
Q4: Does the drive include firmware?
Published product information indicates that firmware must be selected or ordered separately. Verify the installed firmware identifier and required functionality before assuming the replacement is ready to run.
Q5: Can it control any Bosch Rexroth servo motor?
No. The motor’s voltage, current, feedback encoder, power requirements, and mechanical application must be compatible with the drive configuration. Check the motor and drive documentation together.
Q6: Can this unit be installed in an unprotected industrial area?
Its IP20 enclosure is intended for protected installation, typically inside a suitable electrical cabinet. The cabinet must provide the required protection, cooling, grounding, and electrical clearances.
Q7: What should procurement verify before purchasing?
Confirm the full type code and R911327325 order number, interface options, firmware, motor compatibility, physical condition, and test documentation. If the unit is used or refurbished, request photographs of the nameplate and available functional-test records.
