Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E84AVTCE2224SB0 is a 2.2 kW frequency inverter from the 8400 TopLine C series designed for dynamic multi-axis positioning and precise motion control applications. Operating on a three-phase supply range from 320 V AC to 528 V AC, this unit delivers a rated output current of 5.6 A and a maximum output current of 8.4 A. Output frequency is configurable from 0 Hz to 599 Hz with an 8 kHz default switching frequency. The drive supports multiple motor control modes, including V/f characteristic control, sensorless vector control, and full servo control for both asynchronous motors (SC-ASM) and permanent magnet synchronous motors (SC-PSM).
For networking and motor feedback, the drive includes an onboard CANopen system bus interface along with a multi-encoder port supporting resolvers, HTL, TTL, SinCos, and SSI feedback types. Broader control cabinet integration is enabled via an MCI extension slot that accepts fieldbus communication modules, including PROFINET (E84AYCER), PROFIBUS (E84AYCPM), and EtherCAT (E84AYCEC). Putting a replacement unit into service is straightforward: parameters can be transferred without software tools using the removable L-force Memory Module (E84AYMBM) inserted into slot X400, or via software using Lenze EASY Starter and Lenze Engineer. Integrated Safe Torque Off (STO) inputs provide functional safety directly on the drive.
Diagnostic monitoring is provided by four front-panel LEDs indicating drive status (DRIVE-READY, DRIVE-ERROR) and CANopen bus states (CAN-RUN, CAN-ERR). Fault events and operating parameters are recorded in an internal fault history buffer and system log. Initial troubleshooting should verify line input voltage, encoder cable connections, STO input signals, and proper seating of the MCI communication card or memory module. If the DRIVE-ERROR LED remains continuously illuminated red during internal self-testing, or if output short-circuit faults persist with no load connected, an internal hardware failure is present where tested exchange units or repair through ABC Industrial Parts can restore system operation.

Programming and Configuration
Engineering and parameter adjustment for the Lenze E84AVTCE2224SB0 8400 TopLine C inverter are supported by Lenze EASY Starter and Lenze Engineer software (High-Tech / State-Tech versions). These engineering packages allow commissioning technicians to adjust motor parameters, speed ramps, controller dynamics, and feedback options for synchronous and asynchronous motors.
Hardware-based configuration storage is managed using the removable L-force Memory Module (E84AYMBM) fitted in slot X400. This plug-in module retains the complete unit parameter set, enabling rapid offline backup and configuration transfer. For direct cabinet-level parameter access and local control, the unit supports the optional L-force Keypad XT (E84AYKXR).
Communication and System Integration
The E84AVTCE2224SB0 drive features a built-in CANopen system bus interface for multi-axis coordination and distributed drive control. Position and velocity feedback are handled via the onboard multi-encoder port, which directly accepts resolvers, HTL, TTL, SinCos, and SSI encoders without external signal conditioning modules.
Network connectivity can be tailored to upper-level control architectures using optional MCI fieldbus modules installed in the extension slot. Supported options include PROFINET (E84AYCER), PROFIBUS (E84AYCPM), and EtherCAT (E84AYCEC). Direct machine control wiring is supported through physical I/O interfaces consisting of 8 digital inputs, 4 digital outputs, 1 relay output, 2 analog inputs, and 2 analog outputs.
Diagnostics and Status Indication
Four status LEDs on the drive front panel convey operational and bus state information. Drive readiness and fault statuses are reported by DRIVE-READY and DRIVE-ERROR LEDs, while system bus condition is shown by CAN-RUN and CAN-ERR LEDs.
Detailed troubleshooting is supported through an internal fault history buffer that stores recent fault events alongside operating parameters and timestamps. System events can also be read out through CANopen diagnostic objects or via a connected PC running Lenze EASY Starter.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| CAN-RUN | Green - Solid / Blinking / Single Flash | CANopen network status: ON = Operational, Blinking = Pre-Operational, Single Flash = Stopped |
| CAN-ERR | Red - Off / Single Flash / Double Flash / Solid | CANopen bus error: OFF = No error, Single Flash = Warning limit reached, Double Flash = Heartbeat/Guard event, ON = Bus off state |
| DRIVE-READY | Green - Solid / Blinking | Inverter operational readiness: ON = Inverter enabled / ready, Blinking = Inverter disabled / inhibit active |
| DRIVE-ERROR | Red - Blinking / Solid | Drive fault condition: Blinking = Warning active, ON = Trouble/Fault active (Inverter inhibited). Continuous red on internal self-test failure indicates hardware error requiring service. |
Replacement and Spare Part Considerations
Replacing an E84AVTCE2224SB0 drive can be accomplished quickly without software reprogramming by transferring the original L-force Memory Module (E84AYMBM) from slot X400 to the replacement unit. This transfers all user parameters, motor tuning settings, and fieldbus configurations directly upon power-up.
When swapping the unit, ensure that any installed MCI fieldbus module (such as PROFINET E84AYCER or PROFIBUS E84AYCPM) is transferred to the replacement drive's MCI slot and fully seated. Verify that the dual-channel Safe Torque Off (STO) circuit and motor encoder feedback wiring are reconnected correctly according to the machine wiring diagram prior to enabling the power stage.

Frequently Asked Questions
How do I transfer parameters to a replacement Lenze E84AVTCE2224SB0 inverter?
Parameters can be transferred without software tools by removing the L-force Memory Module (E84AYMBM) from slot X400 of the original unit and inserting it into slot X400 of the replacement drive. Alternatively, parameters can be uploaded and restored using Lenze EASY Starter or Lenze Engineer software.
Which motor feedback types are supported by this drive?
The onboard multi-encoder interface supports resolvers, HTL, TTL, SinCos, and SSI encoders for precise dynamic feedback control on synchronous and asynchronous motors.
How do I add PROFINET or PROFIBUS communication to the E84AVTCE2224SB0?
Fieldbus communication is added by inserting an optional MCI module into the extension slot, such as PROFINET E84AYCER, PROFIBUS E84AYCPM, or EtherCAT E84AYCEC.
What does a solid red DRIVE-ERROR LED mean?
A solid red DRIVE-ERROR LED indicates an active drive fault that inhibits output. If it stays lit continuously red during the startup self-test process, an internal hardware failure has occurred requiring repair or unit replacement.
What should I check if code 0x00E0 SafetyFault occurs?
Code 0x00E0 indicates a discrepancy or channel mismatch in the Safe Torque Off (STO) circuit. Check dual-channel STO input wiring and the safety relay output. If inputs are valid and the fault persists, internal safety circuit failure requires factory service.
