HCS01.1E-W0018-A-03-B-ET-EC-NN-L4-NN-FW 18A STO SBC Drive

The HCS01.1E-W0018-A-03-B-ET-EC-NN-L4-NN-FW is a compact single-axis drive controller for machines that require an 18 A current class and integrated drive safety. Its HCS01 construction combines the power section and BASIC control section in one cabinet-mounted unit, reducing the number of separately selected drive components.

This exact configuration uses ET MultiEthernet communication, an EC multi-encoder interface and the L4 safety option. L4 identifies Safe Torque Off together with Safe Brake Control, which is the main purchasing difference from the otherwise similar NN safety version. Firmware is not defined by the FW placeholder and must be matched to the machine project before commissioning.

Key Features

· 18 A maximum current class with 7 A continuous-current reference

· Integrated BASIC control and power sections for a compact single-axis layout

· ET MultiEthernet hardware for flexible industrial Ethernet integration

· EC multi-encoder feedback interface for supported Rexroth and third-party encoder systems

· L4 drive-integrated Safe Torque Off and Safe Brake Control

· IP20 enclosure and internal blower cooling for protected control-cabinet installation

Typical Applications

· Packaging and printing axes requiring brake control

· Handling and assembly stations

· Compact machine-tool feed axes

· Replacement of the same complete HCS01 order code

Compatibility and Selection Note

Use the complete order code and material number R911331608 when selecting a replacement. Do not substitute the NN, L3, S4 or SB safety variants without checking the safety circuit, firmware release, encoder wiring and machine risk assessment.

Frequently Asked Questions

Q1 What distinguishes this L4 version from the NN version?

L4 adds Safe Torque Off and Safe Brake Control. The NN version does not contain that safety option, so the two versions should not be treated as identical replacements.

Q2 Does ET mean that every Ethernet protocol is active?

ET identifies MultiEthernet-capable hardware. The active protocol and supported functions still depend on the installed firmware and project configuration.

Q3 Is the firmware included in the full model code?

No. The FW ending is a placeholder. Confirm the required FWA-INDRV firmware type and version before shipment or commissioning.

Q4 Can this 18 A unit replace a W0028 drive?

Not as a direct assumption. W0018 and W0028 have different current classes and power data. Verify motor load, mains arrangement, braking requirements and machine parameters.

Q5 What should be checked for encoder compatibility?

Confirm the motor encoder type, connector assignment, cable, feedback voltage and firmware support. EC denotes a multi-encoder interface but does not make every motor automatically compatible.

Q6 Where should this IP20 drive be installed?

Install it inside a suitable control cabinet with the specified airflow, grounding, clearance and environmental conditions from the project planning documentation.
