Product Information
The Lenze 00400048 (Type EVF8241-E) is a 0.75 kW frequency inverter from the 8200 Vector drive series designed for precise speed and torque control of three-phase AC motors. Operating on a three-phase input supply range of 320 V AC to 528 V AC at 45 to 65 Hz, this compact IP20 panel-mounted unit delivers a continuous rated output current of 2.4 A at 400 V AC with an output frequency range from 0 to 480 Hz. Supporting both standard V/f characteristic control and sensorless vector control with adjustable switching frequencies up to 16 kHz, the inverter ensures stable speed regulation, acoustic noise reduction, and high dynamic performance across conveyor systems, industrial pumps, ventilation fans, and automated packaging machinery.
Built around a modular architecture, the EVF8241-E features a pluggable function slot for system control and fieldbus communication options, accommodating modules such as PROFIBUS-DP (EMF2133IB), CANopen (EMF2173IB / EMF2178IB), INTERBUS, LECOM, or the Standard I/O Function Module (EMZ8272BB). Commissioning a replacement unit requires transferring operational parameters and configuring the interface module to match the original drive. The inverter contains non-volatile EEPROM memory capable of holding up to four independent parameter sets. Parameters can be copied, edited, or cloned using the optional Keypad XT (EMZ8201BB) or Lenze Global Drive Control (GDC) software. When swapping out a drive in an active production line, migrating the parameter backup and fieldbus module ensures complete system alignment, a process where technical assistance from ABC Industrial Parts can assist in minimizing machine downtime.
Operational monitoring and fault diagnosis are managed through integrated visual indicators and parameter tracking. A dual-color Red/Green LED displays overall drive and module status, signaling solid or flashing green during normal operation or standby, and turning red during TRIP fault or warning states. Detailed fault history can be reviewed by accessing TRIP memory parameter C0168 via Keypad XT or live diagnostic views in Global Drive Control software. Monitored fault conditions include short circuits (OC1), ground faults (OC2), overcurrent (OC5), DC bus overvoltage (OU), undervoltage (LU), and thermal overload (OH, OH4, OH7). While parameter faults (PR) can be resolved by loading factory defaults (parameter C0002 = 1) and reloading configurations, internal hardware or memory errors such as EE, H10, or H11 indicate component failures that are not field-serviceable. In these instances, sourcing a fully tested exchange unit or utilizing repair options through ABC Industrial Parts provides a fast route back to full operation.

Programming and Configuration
Configuration of the Lenze EVF8241-E 8200 Vector inverter is conducted using either the optional Keypad XT (EMZ8201BB) diagnostic module or Lenze Global Drive Control (GDC) engineering software. The internal non-volatile EEPROM stores up to four separate parameter sets, allowing engineers to maintain multiple operating profiles or restore baseline drive settings directly on the hardware.
When commissioning a spare unit, default parameters can be loaded by setting parameter C0002 to 1, resetting the drive memory prior to uploading tailored settings. Drive cloning is supported via Keypad XT, enabling rapid transfer of complete parameter profiles between drives on the plant floor without needing a direct PC connection.
Communication and System Integration
The EVF8241-E main drive power block features a pluggable module interface slot, allowing flexible integration into various industrial fieldbus networks without requiring modification of the base inverter unit.
Supported communication modules include the PROFIBUS-DP Module (EMF2133IB) and CANopen Modules (EMF2173IB / EMF2178IB), in addition to INTERBUS and LECOM options. For standard hardwired control, the Standard I/O Function Module (EMZ8272BB) provides discrete digital and analog terminal connections for speed references and control commands.
Diagnostics and Status Indication
Drive operating status and fault conditions are communicated through visual LED indication and readable parameter records. The front status LED displays dual-color output to signal normal operational state, standby modes, or active fault warnings.
Detailed fault evaluation is performed by querying parameter C0168 via Keypad XT to inspect the saved TRIP history. For continuous monitoring, Lenze Global Drive Control (GDC) software provides real-time status tracking, motor current observation, and active error code logging.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Drive / Module Status | Red / Green - Solid or Flashing | Green indicates normal operation or standby status; Red indicates a TRIP fault or warning condition. |
Replacement and Spare Part Considerations
When replacing a Lenze EVF8241-E frequency inverter, verify that the replacement unit matches the required power specifications (0.75 kW, 2.4 A continuous output, 320–528 V AC input). Operating physical dimensions and IP20 enclosure characteristics ensure direct mounting compatibility inside existing control cabinets.
Because operational settings and fieldbus interfaces are determined by option modules, transfer the existing function module (such as PROFIBUS EMF2133IB, CANopen EMF2173IB/EMF2178IB, or Standard I/O EMZ8272BB) onto the replacement base drive. Download the saved parameter set or clone parameters using Keypad XT (EMZ8201BB) to restore correct acceleration ramps, motor data, and bus addresses before enabling motor power.

Frequently Asked Questions
What software is used to configure the Lenze EVF8241-E inverter?
The inverter is configured using Lenze Global Drive Control (GDC) software or manually configured using the optional Keypad XT (EMZ8201BB) plug-in display module.
How do I clone parameters from a failed EVF8241-E drive to a spare unit?
Parameters can be copied onto a Keypad XT (EMZ8201BB) module from the working configuration, attached to the replacement drive, and transferred into internal memory. Alternatively, parameter sets can be uploaded and downloaded using Global Drive Control (GDC) software.
What does a solid red LED indicate on the drive status display?
A solid or flashing red status LED indicates a TRIP fault or warning condition. The exact cause can be evaluated by checking parameter C0168 via Keypad XT or reviewing active errors in Global Drive Control software.
How can I resolve parameter error code PR?
Fault code PR indicates parameter set corruption. Reset the unit to factory defaults by setting parameter C0002 to 1, then reload the original parameter backup file.
What should I do if the inverter displays fault codes EE, H10, or H11?
Fault codes EE, H10, and H11 indicate internal hardware, micro-controller, or EEPROM failures on the control board. If power cycling does not clear the error, the unit must be repaired or replaced.
