The 6SL3040-0PA00-0AA1 is a CUA31 Control Unit Adapter developed to connect compatible PM340 and PM240-2 Blocksize Power Modules to a DRIVE-CLiQ-based drive control system.
The adapter is installed directly on the compatible Power Module and provides the communication interface required between the power stage and a connected Control Unit or motion controller.
It does not independently execute motor-control algorithms, store the complete machine program or supply motor power. Its role is to adapt the Blocksize Power Module for communication and control within the modular drive architecture.
This makes the 6SL3040-0PA00-0AA1 particularly relevant for machines that combine a central DRIVE-CLiQ controller with individual PM340 or PM240-2 Power Modules.
The CUA31 should be selected using the complete order number, Power Module type and hardware version. Physical similarity alone is not sufficient for replacement.

Adapter Function
The 6SL3040-0PA00-0AA1 provides the interface between a compatible Blocksize Power Module and the higher-level drive controller.
Typical signal path:
Automation Controller
Control Unit or Motion Controller
DRIVE-CLiQ
CUA31 Adapter
PM340 or PM240-2 Power Module
Connected Motor
The adapter therefore acts as a communication and integration component rather than the main controller.
Compatible Power Modules
The CUA31 is intended for use with:
- PM340 Blocksize Power Modules
- Supported PM240-2 Power Modules
Compatibility with PM240-2 depends on the CUA31 hardware version and Power Module configuration.
Before replacement, confirm:
- CUA31 hardware revision
- PM240-2 hardware version
- Power Module frame size
- Firmware compatibility
- DRIVE-CLiQ system topology
- Original machine documentation
DRIVE-CLiQ Integration
DRIVE-CLiQ provides digital communication between the CUA31 and the connected control system.
Typical functions include:
- Power Module identification
- Operating-status transfer
- Parameter communication
- Fault and warning diagnostics
- Control-command transmission
- System topology detection
The maximum permitted cable length depends on the product version and installation conditions.
CUA31 vs Control Unit
CUA31 Adapter
Provides the interface between a Blocksize Power Module and DRIVE-CLiQ.
Control Unit
Executes motor control, processes drive parameters and coordinates the drive system.
The CUA31 cannot replace a CU320, CU320-2 or another full Control Unit.
CUA31 vs CUA32
CUA31
Power Module adapter without an integrated incremental encoder interface.
CUA32
Power Module adapter with an additional interface for supported HTL or TTL incremental encoders.
Select the CUA32 only when the encoder-interface requirement matches the machine design.
Safety Function Support
The CUA31 can be used in drive configurations supporting extended Safety Integrated functions.
The available safety functions depend on:
- Connected Control Unit
- Safety communication
- Firmware version
- Motor feedback
- Safety licensing
- Machine safety configuration
The adapter itself should not be described as a complete safety controller.
System Integration
A typical operating system may include:
- PLC or machine controller
- Control Unit
- DRIVE-CLiQ cable
- CUA31 adapter
- PM340 or PM240-2 Power Module
- Compatible motor
- Motor feedback device
- Approved drive parameters
The exact hardware combination must follow the original drive-system design.

Do not replace the adapter using only the CUA31 name or physical appearance.
Installation Guidelines
Disconnect the complete drive-system power.
Wait for the DC link to discharge fully.
Verify the absence of hazardous voltage.
Confirm the exact adapter model.
Inspect the Power Module mounting interface.
Check connector condition.
Install the CUA31 securely.
Connect DRIVE-CLiQ correctly.
Verify the system topology.
Restore approved drive parameters.
Test motor operation at reduced speed.
Check faults and diagnostic messages.
Installation should be completed by qualified drive-system personnel.
FAQ
Q1: What is 6SL3040-0PA00-0AA1?
A1: It is a CUA31 Control Unit Adapter for connecting compatible PM340 and PM240-2 Power Modules to a DRIVE-CLiQ control system.
Q2: Is it a complete Control Unit?
A2: No. It is an adapter. The connected Control Unit performs the actual motor-control functions.
Q3: Does it directly power a motor?
A3: No. Motor power is supplied by the connected Power Module.
Q4: Which Power Modules are compatible?
A4: It is designed for PM340 and supported PM240-2 Blocksize Power Modules.
Q5: Does every PM240-2 work with this adapter?
A5: Compatibility depends on the CUA31 hardware revision and the Power Module version. Both must be verified.
Q6: What communication system does it use?
A6: It uses DRIVE-CLiQ communication.
Q7: Does CUA31 include an encoder interface?
A7: No. Applications requiring a supported HTL or TTL incremental encoder interface may require a CUA32.
Q8: Can it replace a CU320 Control Unit?
A8: No. A CUA31 adapter and a CU320 Control Unit perform different functions.
Q9: Does it support safety functions?
A9: It can be used in compatible systems supporting extended Safety Integrated functions, but the full safety function depends on the complete system.
Q10: Where is it commonly used?
A10: It is used in modular conveyor, packaging, material handling and production-machine drive systems.
