Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00490725, model designation E82MV251_2B001, is a decentralized frequency inverter belonging to the 8200 vector product family and 8200 Motec series. Rated for a continuous output power of 0.25 kW (0.33 HP) with an output current of 1.7 A, this compact drive operates on 230 V AC single-phase or three-phase supply configurations across an input tolerance range of 180 V to 264 V AC. Built with an IP65 rated enclosure, the unit is constructed for direct mounting on standard AC asynchronous motors or localized wall installation on machine frames. This decentralized design eliminates central control cabinet requirements, shortens motor wiring runs, and reduces electromagnetic interference across applications such as conveyor belts, industrial pumps, fans, and material handling systems.
To facilitate system integration, the E82MV251_2B001 utilizes a modular interface structure that separates the core drive control section from fieldbus interface modules. The drive supports pluggable modules for CANopen, PROFIBUS-DP, INTERBUS, and AS-Interface networks without altering the base drive module. Commissioning a replacement unit requires parameter set configuration, as up to four complete parameter sets can be stored inside internal non-volatile EEPROM memory. Parameter management and configuration transfers are performed using the optional XT Keypad module (E82ZBC) or Lenze Global Drive Control (GDC) PC software. When restoring a machine to service, parameter set copying and correct function module seating are key steps, with ABC Industrial Parts providing expert support and tested spare units to simplify replacement.
Diagnostics and operating status are displayed via an integrated dual Red/Green status LED that indicates drive state, standby mode, warnings, and TRIP conditions. The inverter tracks active diagnostic data and logs the last four TRIP events with operating hour timestamps, accessible via parameter C0161 for active faults and parameter C0168 for fault history using a keypad or GDC software. Trip indications cover issues such as acceleration overcurrent (OC1), DC bus overvoltage (OU), motor overtemperature (OH4), and module slot communication faults (CE0). While initial maintenance involves checking mains supply wiring, line fuses, motor connections, and external sensor circuits, internal control board issues like EEPROM corruption (EE) or microcontroller failure (H05) are non-serviceable in the field. Under these conditions, sourcing a tested exchange drive or unit repair through ABC Industrial Parts provides a direct route back to full operation.

Programming and Configuration
Parameter setup and configuration management for the Lenze 00490725 frequency inverter are conducted through Lenze Global Drive Control (GDC) PC software or locally via the optional XT Operating Module (E82ZBC) keypad. The drive includes non-volatile EEPROM memory capable of retaining up to four independent parameter sets. This feature allows different machine configuration profiles to be stored directly within the drive and swapped as operational requirements demand.
When commissioning or replacing an E82MV251_2B001 inverter, parameter sets must be transferred from the original unit or downloaded from a saved software project. If resetting the device to default conditions is required during testing, executing parameter C0002 = 1 restores factory settings. Proper motor thermal characteristics must also be configured in parameters C0087 and C0088 to match connected motor ratings and prevent false thermal overload TRIP conditions.
Communication and System Integration
The E82MV251_2B001 features a modular communication layout where network interface modules plug into the dedicated control slot on the front of the drive. This architectural separation allows the core power electronics and frequency drive logic to remain intact while swapping fieldbus interfaces as machine control architectures evolve.
Available interface options for the 8200 Motec platform include CANopen, PROFIBUS-DP, INTERBUS, and AS-Interface modules. Reliable network integration depends on verifying full mechanical engagement between the module and header pins, as well as proper cable grounding and shielding. A loss of communication between the core inverter logic and the plugged module triggers fault code CE0.
Diagnostics and Status Indication
Visual operational feedback on the Lenze 00490725 drive is provided by a dual Red/Green status LED. The LED emits continuous or flashing patterns to indicate normal drive running states, standby status, active operational warnings, or tripped fault conditions.
For detailed fault analysis, current drive errors are viewed in parameter C0161 via the XT Keypad or GDC PC software online window. Historical troubleshooting is supported by parameter C0168, which records the last four TRIP codes alongside their exact operating hour timestamps. This historical log assists technicians in isolating intermittent trip causes such as momentary overvoltage or thermal overloads.
Status LED Indicators
| LED | Color/Status | Meaning |

| Status LEDs | Red / Green - Solid / Flashing | Indicates operational state, standby mode, active warnings, and TRIP faults |
Replacement and Spare Part Considerations
The Lenze 8200 Motec series, including part number 00490725, is officially discontinued by the manufacturer. For existing automated facilities maintaining legacy production lines, sourcing direct replacement spares minimizes physical installation modifications due to the specialized IP65 form factor. For complete machine redesigns or long-term system modernizations, Lenze recommends the i550 protec series as a modern replacement option.
When swapping out a faulty unit for a replacement 00490725 drive, parameter sets must be transferred using either the XT Keypad or Global Drive Control software. An unconfigured drive or an invalid parameter upload will result in a P13 fault code, while improper module insertion leads to a CE0 error. Verifying physical pin condition on the module slot header prior to mounting ensures reliable fieldbus communications.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| OC1 | Acceleration Overcurrent | Output current exceeded peak limit during acceleration ramp | Short circuit at output terminals, earth fault on motor cable, motor cable too long, acceleration time setting too short | Check motor and cable for short circuits and ground faults; increase acceleration time; check motor size matching. |
| OC2 | Deceleration Overcurrent | Output current exceeded peak limit during deceleration ramp | Deceleration time set too short; mechanical overload or jammed motor shaft | Increase deceleration time; install brake resistor if applicable; check mechanical drive train. |
| OC5 | I2t Motor Overload | Motor load exceeded I2t thermal limit over time | Continuous operation under overload conditions, motor under-dimensioned, low motor speed with excessive load | Reduce motor load; check drive sizing; verify parameter C0087/C0088 thermal characteristic settings. |
| OU | DC Bus Overvoltage | DC bus voltage exceeded upper threshold (~400V for 230V devices) | Regenerative energy from motor during braking with deceleration time too short | Extend deceleration ramp time (C0013); check brake resistor / chopper circuit. |
| LU | DC Bus Undervoltage | DC link voltage dropped below lower operation threshold | Mains supply failure, supply voltage drop under load, loose mains connection | Check supply voltage mains; check fuses and wiring connections. |
| OH | Inverter Overtemperature | Heatsink temperature exceeded upper limit (> 90°C) | Inadequate cooling air flow, ambient temperature too high, heavy continuous overload | Clean heatsink cooling fins; improve cabinet/mounting ventilation; reduce switching frequency or load. |
| OH4 | Motor Temperature Fault | Motor thermal sensor (PTC/TK) detected overheating | Motor thermal overload, cooling fan failure on motor, incorrect PTC wiring or sensor setup | Allow motor to cool down; check motor load and forced ventilation fan; verify PTC connection on terminals. |
