Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13131452 (type designation E82MV251_2B001) is a 0.25 kW frequency inverter from the 8200 motec series designed for decentralized motor speed control. Operating with a rated input supply voltage of 230 V AC across a 180 to 264 V AC range, this drive delivers a continuous output current of 1.7 A and an output frequency range of 0 to 480 Hz. Housed in a heavy-duty IP65 enclosure that protects against dust and moisture, the unit supports direct mounting onto a motor terminal box or adjacent wall mounting, eliminating the need for space-consuming centralized control cabinets in conveyor systems, packaging machinery, and pumping applications.
To integrate with automation networks and control architectures, the E82MV251_2B001 features a modular interface slot that accepts plug-in communication modules including CANopen (E82ZAFCC), PROFIBUS (E82ZAFPC), and AS-Interface (E82ZAFAC), as well as DeviceNet and LECOM RS-232/485. Putting a spare drive into service requires parameter alignment to match the original application setup, as standard units will not operate machine profiles without configuration. Parameters can be backed up and downloaded using Lenze Global Drive Control (GDC) software or copied directly using the Keypad XT (EMF2171IB / E82ZBC) parameter cloning feature across four non-volatile EEPROM memory sets. ABC Industrial Parts can support maintenance teams with replacement units and parameter management guidance to minimize downtime during drive swap-outs.
Diagnostics are indicated directly on the drive cover by status LEDs, where a solid green light indicates normal ready operation and a red light signals an active fault condition. Internal fault memory parameters C0161 and C0168 store a log of trip events readable via the Keypad XT or GDC software monitor. When diagnosing trips such as overvoltage (OU), undervoltage (LU), motor phase loss (LP1), or module communication timeouts (CE0, CE1, CE2), initial checks should cover main AC voltage stability, motor terminal connections, fieldbus wiring, and module seating. If persistent EEPROM errors (EEr) or internal hardware failures occur that cannot be cleared by restoring factory defaults (C0002 = 1), a tested exchange unit from ABC Industrial Parts offers a fast solution to restore production.

Programming and Configuration
Drive configuration and operating setup for the Lenze E82MV251_2B001 are performed using either Lenze Global Drive Control (GDC) software or a plug-in Keypad XT (EMF2171IB / E82ZBC). The inverter is equipped with internal non-volatile EEPROM memory capable of storing up to four independent, switchable parameter sets. Control algorithms can be configured for linear or quadratic V/f characteristic curves as well as sensorless vector control, with adjustable switching frequencies from 2 kHz up to 16 kHz to optimize acoustic motor performance.
During routine drive swaps or commissioning, the Keypad XT parameter cloning function allows complete parameter profiles to be copied directly from one unit to another without a PC connection. If software reconfiguration or memory re-initialization is required, setting parameter C0002 to 1 reloads the factory default parameter set into the EEPROM, providing a clean baseline for application re-programming.
Communication and System Integration
The Lenze 8200 motec E82MV251_2B001 utilizes a modular architecture built around an integrated plug-in interface slot. This design enables flexible adaptation to diverse industrial automation systems without altering the base power unit. Depending on system requirements, optional function modules can be attached to support fieldbus protocols including CANopen (E82ZAFCC), PROFIBUS (E82ZAFPC), AS-Interface (E82ZAFAC), DeviceNet, and LECOM RS-232/485.
Internal communication between the drive control board and the installed module is maintained via direct plug connectors. Correct seating of the function module and accurate configuration of bus parameters, node addresses, and baud rates on the network master are required to maintain continuous data exchange and prevent fieldbus interface timeout errors.
Diagnostics and Status Indication
Visual operational status on the E82MV251_2B001 is provided by diagnostic LEDs located on the drive cover. A solid green 'Ready' LED indicates normal operation and readiness for run commands, while a solid or flashing red 'Fault' LED signals an active trip condition. Real-time operating variables and active status states can also be monitored via Lenze Global Drive Control (GDC) or the EMF2171IB Keypad XT display.
Detailed fault records are retained in internal diagnostic registers. Codes recorded in history parameters C0161 and C0168 assist maintenance staff in identifying conditions such as motor overcurrent (OC1), earth faults (OC2), DC bus overvoltage (OU), undervoltage (LU), or thermal overloads (OH, OH4, OH8).
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Ready | Green - Solid | Inverter operating normally / Ready for operation |
| Fault | Red - Solid / Flashing | Inverter fault / trip condition active |
Replacement and Spare Part Considerations
When replacing a failed Lenze E82MV251_2B001 drive, verify both the part number (13131452) and the full type designation to guarantee electrical and physical compatibility. Selecting a unit with matching power ratings (0.25 kW) and voltage specifications (230 V AC) ensures proper motor power delivery and mechanical alignment when mounted to a motor terminal box.
During unit replacement, any plug-in fieldbus module attached to the interface slot must be transferred to the replacement inverter or reconfigured to match network communication parameters. Additionally, parameter data stored in the original drive's EEPROM must be transferred using the Keypad XT cloning feature or Global Drive Control (GDC) software to restore motor settings, acceleration profiles, and control terminal assignments.
