Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E84AVHCE7512SX0 is a cabinet-mounted frequency inverter from the 8400 Highline C series, designed for controlled electric motor applications requiring precise speed and torque management. Delivering a rated power output of 0.75 kW with a 4 A rated output current and a maximum output current of 6 A, this unit operates across an input voltage range of 180 to 264 V AC (230 V AC nominal). The unit features an IP20 enclosure rating and supports standard V/f control, Sensorless Vector Control (SLVC), and closed-loop Vector Control (VC) across an output frequency range of 0 to 599 Hz. It includes integrated Safe Torque Off (STO) functionality certified to SIL 3 (IEC 61508) and Performance Level e (EN ISO 13849-1), providing hardware-based safety without extra external contactors.
System wiring and control integration are managed through 8 digital inputs, 4 digital outputs, 2 bipolar analog inputs, and 2 analog outputs, along with an onboard CANopen system bus interface. The inverter includes an extension slot to accommodate optional fieldbus communication modules for PROFINET, PROFIBUS-DP, EtherCAT, or EtherNet/IP networks. Commissioning a replacement unit is straight-forward due to the hardware-based Lenze Memory Module slot. By transferring the physical Memory Module (MM200 or MM300) from an existing drive to the spare unit, parameter configurations are immediately retained without requiring software connection. When parameter setup or system tuning is performed online, options include Lenze EASY Starter or Lenze Engineer software via the USB Diagnostic Adapter (E84AYCER), or direct local configuration using the Keypad XT (E84AYKCE). Expert assistance from ABC Industrial Parts can assist maintenance teams with spare sourcing and hardware preparation.
Operational diagnostic feedback is available through four front panel status LEDs: DRIVE READY, DRIVE ERROR, CAN RUN, and CAN ERR. Detailed fault tracking can be carried out via the Keypad XT display, PC diagnostic adapters, or CANopen diagnostic objects. Standard troubleshooting procedures should verify mains power levels on terminals, motor winding insulation resistance, and CANopen network termination resistors (120 Ohm) when bus faults occur. Common operational trips include motor short circuits (0x0011), DC-bus overvoltage (0x0021), DC-bus undervoltage (0x0031), or heatsink overtemperature (0x0051). If a internal hardware fault (0x00F1) or temperature sensor failure (0x0052) is indicated, internal repairs are required. Returning the damaged component for professional repair or acquiring a fully tested replacement from ABC Industrial Parts offers a dependable path to restoring machine operation.

Programming and Configuration
Parameter setting and drive commissioning for the Lenze E84AVHCE7512SX0 are managed through Lenze engineering toolsets, including EASY Starter and Lenze Engineer. These software environments support full parameterization, axis tuning, and offline project creation. Connection between a PC and the inverter drive is established using the optional USB Diagnostic Adapter (E84AYCER), allowing real-time monitoring and diagnostic data transfer.
For localized setup without a computer, the plug-in Keypad XT (E84AYKCE) provides a clear screen interface to view error codes, alter parameters, and execute quick drive setups. System parameters, motor profiles, and application settings are stored directly on the removable Lenze Memory Module (MM200 or MM300). This non-volatile storage card permits fast transfer of configured drive setups directly between hardware units during maintenance.
Communication and System Integration
The Lenze E84AVHCE7512SX0 features an integrated CANopen system bus interface for multi-drive networking and real-time motion synchronization. The onboard CANopen interface allows direct access to internal drive parameters, control words, and diagnostic object registers across the bus network.
To enable higher-level industrial automation communication, the drive includes a dedicated extension slot for optional fieldbus communication modules. Supported protocols include PROFINET (E84AYCER), PROFIBUS-DP (E84AYCPM), EtherCAT (E84AYCEC), and EtherNet/IP (E84AYCEO). Terminal connections also provide 8 digital inputs, 4 digital outputs, 2 bipolar analog inputs, and 2 analog outputs for direct sensor and actuator integration.
Diagnostics and Status Indication
The front panel of the E84AVHCE7512SX0 incorporates LED indicators that offer clear status feedback regarding drive operation and fieldbus activity. These lights display real-time conditions for operational readiness, fault states, and CANopen communication status.
Detailed diagnostics are accessible by attaching the Keypad XT module or connecting a PC loaded with Lenze EASY Starter via the USB Diagnostic Adapter. Active fault conditions generate visual code outputs alongside subcodes, enabling rapid isolation of power supply, cabling, thermal, or motor load faults.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| DRIVE READY | Active | Indicates operational readiness status of the inverter drive |
| DRIVE ERROR | Active | Indicates active drive fault or alarm condition |
| CAN RUN | Active | Indicates status of the onboard CANopen system bus interface |
| CAN ERR | Active | Indicates communication error on the CANopen bus |
Replacement and Spare Part Considerations
When replacing a failed Lenze E84AVHCE7512SX0 inverter, ensure the replacement unit matches the exact 0.75 kW power rating and 230 V supply voltage requirements. Verify whether optional communication modules (such as PROFINET or PROFIBUS) are installed in the existing unit's extension slot, as these must be moved to the replacement drive to preserve network integration.
Downtime during unit swap-out can be reduced by transferring the plugged Lenze Memory Module (MM200 or MM300) from the original drive to the replacement hardware. This avoids manual parameter entry or laptop software uploads. Before re-commissioning, verify that safety wiring connected to the Safe Torque Off (STO) terminals is correctly terminated to ensure full SIL 3 / PL e safety operation.
