Features:
- Two resolver-feedback axes support speed-setpoint or torque-setpoint control in a SIMODRIVE 611 group.
- Per-axis analog and digital I/O connect commands, status signals, and commissioning functions.
- Serial access, removable parameter memory, and optional PROFIBUS-DP communication support service work.
Siemens 6SN1118-0NK01-0AA2 is the HRS2 resolver version of the SIMODRIVE 611 universal two-axis control unit.
Its two channels combine resolver processing with analog and digital I/O, test access, an operator display, and speed or torque control functions.
The memory module and optional terminal or PROFIBUS-DP module must be matched to the machine parameter set, software state, and existing interface wiring.
The Siemens 6SN1118-0NK01-0AA2 SIMODRIVE 611 Universal HRS2 Two-Axis Resolver Control Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Two-Axis Feedback Structure
- Axis channels: One control unit manages two drive axes.
- Feedback type: The NK01 variant is assigned to resolver motor feedback.
- Setpoint modes: The channels support configured speed or torque setpoint operation.
- Variant control: The full order number must be checked because adjacent 6SN1118 variants use different measuring systems.
Drive Command and Status Signals
- Analog inputs: Two analog inputs are available for each drive channel.
- Analog outputs: Two analog outputs per channel support configured monitoring signals.
- Digital inputs: Four inputs per drive connect assigned control functions.
- Digital outputs: Four outputs per drive report the configured operating states.
Parameter Retention and Interface Modules
- Memory module: Replaceable storage retains the control-unit parameter set.
- Terminal option: A terminal module can expand hardwired signal access.
- Fieldbus option: A PROFIBUS-DP module provides configured network communication.
- Service boundary: Memory content, option type, connector assignments, and software state must be matched before exchange.
Startup and Diagnostic Access
- Serial interface: RS232 or RS485 supports parameterization and diagnostic access.
- Local display: The onboard operator unit presents selected status and parameter information.
- Test sockets: Two sockets provide defined commissioning measurement points.
- Safety check: Safe-start-inhibit wiring and machine interlocks must be proven before enabling either axis.
