Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00386337 EVD471-E is a compact 0.75 kW digital frequency inverter from the Lenze 470 Series, engineered for precise speed regulation of three-phase AC induction motors. Operating on a 3-phase 400 V AC line supply across an input voltage range of 320 V to 460 V AC, this drive delivers a continuous rated output current of 2.3 A and an output frequency range from 0 to 480 Hz. Housed in an IP20 enclosure suited for control cabinet installation, the unit supports both standard V/f characteristic control and open-loop vector control, providing optimized dynamic torque and speed stability for industrial conveyor belts, centrifugal pumps, cooling fans, and automated packaging systems.
Connecting the drive into a control cabinet is facilitated by a removable X5 plug-in screw terminal block, which provides connections for digital control inputs, analog setpoints in either 0-10 V or 0-20 mA formats, and an integrated relay fault output. Communication capabilities are provided via an integrated LECOM interface slot that accepts plug-in serial modules including LECOM-A (RS232) and LECOM-B (RS485), as well as PROFIBUS-DP fieldbus modules such as the 2131IB and 2133IB. Commissioning a replacement unit requires a full parameter transfer, as operational profiles are stored internally in non-volatile EEPROM across two distinct parameter sets; backups and restores can be carried out using an optional 2102IB keypad module or via PC using Lenze Global Drive Control software, with technical guidance available through ABC Industrial Parts.
System monitoring and status feedback are handled through front-mounted LED indicators and structured internal registers. Green and red status LEDs provide real-time operational feedback, signaling normal controller enable, active controller inhibit, current limits, warnings, or TRIP fault states. Active TRIP codes are stored in Parameter P00 and historical fault occurrences are retained in Parameter P01, both accessible through the 2102IB keypad or the diagnostic window in Lenze Global Drive Control software. Basic commissioning checks should confirm proper line supply phase voltages, correct terminal seating, and intact fieldbus cabling; if a solid red TRIP light persists following a complete power cycle, an internal hardware failure is indicated, and procuring a tested replacement or utilizing ABC Industrial Parts repair support provides a fast path to restoring machine operations.

Programming and Configuration
Programming the Lenze 00386337 EVD471-E frequency inverter is managed through non-volatile internal EEPROM memory capable of holding two complete, independent parameter sets. This dual parameter set architecture allows maintenance teams to store alternative operational profiles for different machinery setups or operating modes directly on the inverter.
Parameter management can be performed directly at the unit using the optional 2102IB keypad operating unit or remotely via a connected computer running Lenze Global Drive Control (GDC) software. Keypad connection allows rapid parameter modification and parameter copying between identical drives, while GDC software provides comprehensive offline parameter file backup, graphical commissioning tools, and parameter download functionality during unit replacement.
Communication and System Integration
The Lenze EVD471-E features a modular interface architecture designed to interface with upper-level automation systems. The primary serial/fieldbus interface slot accepts modular serial interface cards, including LECOM-A (RS232) and LECOM-B (RS485) modules for direct point-to-point or multi-drop serial network connections.
For integration into fieldbus networks, the drive supports PROFIBUS-DP option modules, including the 2131IB and 2133IB adapters. Physical control wiring is established via the X5 removable plug-in screw terminal block, which accepts both 0-10V and 0-20mA analog setpoints, digital control inputs, and an internal relay output for remote status or fault reporting.
Diagnostics and Status Indication
Front-panel status monitoring on the Lenze 00386337 frequency inverter is provided by dual status LEDs. The green LED signals operational readiness and state changes, illuminating solid when the controller is enabled and flashing when controller inhibit (CINH) is active. The red LED alerts operators to TRIP fault states, illuminating solid when the drive output is disabled due to a fault, flashing during active current limit or warning conditions, and remaining solid across power cycles in the event of an unrecoverable internal hardware failure.
Detailed fault analysis is supported through internal parameter registers and software diagnostic windows. Parameter P00 displays active TRIP codes directly on the 2102IB keypad module, while Parameter P01 maintains an internal fault memory log for past error events. Real-time online monitoring of motor parameters, DC bus voltage, and status flags is accessible via the diagnostic window in Lenze Global Drive Control (GDC) software.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green LED (Operation) | Green - Solid or Flashing | Solid ON indicates drive ready / controller enabled. Flashing indicates controller inhibit active (CINH). |
| Red LED (TRIP / Fault) | Red - Solid or Flashing | Solid ON indicates TRIP fault state active and output disabled. Flashing indicates warning or current limit reached. Persistent solid light after power cycle indicates hardware failure. |
Replacement and Spare Part Considerations
When replacing an existing Lenze 00386337 EVD471-E drive, ensure that the power rating (0.75 kW) and supply voltage (400 V AC) match the original unit specifications. Because frequency inverters store application-specific parameters in non-volatile internal EEPROM, a replacement drive will not function correctly without downloading or copying the existing machine configuration.
Parameter backup files can be transferred to the spare unit using the 2102IB plug-in keypad module or loaded directly via Lenze Global Drive Control (GDC) software over a LECOM connection. In instances where the original drive has suffered an electronic fault preventing keypad communication, parameter extraction from the internal EEPROM or donor unit may be required to recover non-documented parameter sets.
Always transfer the existing communication interface module—such as a LECOM-A, LECOM-B, or PROFIBUS-DP 2131IB / 2133IB module—to the replacement inverter. Verify that address switches, fieldbus baud rates, and terminal block connections are verified prior to re-energizing the machine line supply.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| OH | Heatsink Overtemperature | Inverter heatsink temperature exceeds maximum allowed operating limit (>85°C). | Ambient temperature too high, cooling fan failed or blocked, cabinet ventilation inadequate, excessive load. | Check cabinet ventilation, clean heatsink cooling fins, verify ambient temperature is within limits, reduce load. |
| OH3 | Motor Overtemperature | Motor PTC sensor connected to control terminal triggered overtemperature. | Motor overloaded, cooling fan on motor defective, prolonged operation at low speed under heavy load. | Allow motor to cool down, inspect motor cooling fan, reduce mechanical load. |
| LU | Undervoltage | DC bus voltage dropped below minimum threshold limit. | Mains voltage supply drop, phase loss on AC line input, power outage. | Check input mains line voltage across all three supply phases, verify supply fuses and wiring. |
| OU | Overvoltage | DC bus voltage exceeded maximum allowable voltage limit. | Excessive regenerative energy from motor during deceleration, deceleration time set too short, missing braking resistor. | Increase deceleration time (ramp time), fit external brake chopper / braking resistor, check supply voltage stability. |
| OC1 | Short Circuit / Overcurrent | Instantaneous overcurrent detected during acceleration or operation. | Short circuit at inverter output terminals, earth fault in motor cable, acceleration time set too short, motor seized. | Check motor and motor cable for phase-to-phase short circuits and ground faults. Increase acceleration ramp time. If fault occurs immediately with motor disconnected, internal hardware fault — return unit for repair. |
| OC2 | Overcurrent Deceleration | Peak current limit exceeded during motor deceleration. | Deceleration ramp too steep, mechanical blockage during braking. | Extend deceleration time parameter, check mechanical drive system. |
| OC5 | Overload / Constant Speed Overcurrent | Continuous overload current detected at constant output speed. | Mechanical overload, motor jammed, wrong motor parameter settings. | Check motor size vs drive rating, check mechanical system for binding or jamming. |
| EE | EEPROM Fault | Internal parameter memory checksum error or EEPROM write/read failure. | Power interrupted during parameter save operation, corrupted EEPROM chip. | Reset parameters to factory default setting. If error persists after default reset and power cycle, internal hardware fault — return unit for repair. |
| CE0 | Communication Error | Loss of communication via LECOM or optional fieldbus module. | Defective communication cable, loose interface module connection, incorrect bus address or baud rate, fieldbus timeout. | Check interface module seating, verify serial/fieldbus cable connections, confirm baud rate and address settings. |
| LP | Motor Phase Loss | Loss of one output phase to the connected motor. | Broken motor cable phase conductor, loose terminal connection, motor contactor opened during operation. | Check output wiring and motor terminal connections, inspect output contactors if present. |
