Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13435816 E82EV251_2C is a compact 0.25 kW variable frequency drive from the 8200 Vector series, engineered to provide controlled speed and torque regulation for three-phase AC motors. Designed with an IP20 open chassis form factor, this drive accommodates supply voltages from 180 to 264 V AC across single-phase or three-phase power connections. It delivers a continuous output current of 1.7 A and supports up to 2.55 A for short peak load durations of up to 60 seconds, utilizing either V/f characteristic control or sensorless vector control across output frequencies from 0 to 480 Hz.
Integrating a spare drive into an existing control system requires matching both the hardware interface and the specific parameter set. The unit features a plug-in slot that accepts various function modules, enabling flexible terminal connections or direct fieldbus communication. When swapping an existing drive, parameters must be transferred from the original unit to the replacement using the optional Keypad XT module or software tools such as Lenze Global Drive Control or EASY Starter. Parameter sets can be backed up and cloned across units to replicate ramp times, switching frequencies, and control settings, while technical support from ABC Industrial Parts can assist maintenance teams with parameter extraction or pre-configuring spare units prior to installation.
Diagnostic information is displayed directly on the unit via status indicators and parameter registers. Dual LEDs provide immediate operational status, distinguishing between active drive operation, inhibited states, warning conditions, and trip faults. Detailed operational history can be queried through parameter C0013, while real-time drive status is monitored in register C0183 or through connected software. In the event of a rapid-flashing red LED indicating an internal memory checksum failure or EEPROM error, resetting the drive to factory defaults via parameter C0002 may clear the state; if hardware faults persist, ABC Industrial Parts provides tested exchange units and repair services to minimize system downtime.

Programming and Configuration
Drive commissioning and parameter management for the Lenze E82EV251_2C are managed through the optional Keypad XT module (E82ZBC) or PC-based software packages including Lenze Global Drive Control (GDC) version 4.0 or higher and Lenze EASY Starter. Parameter settings dictate motor acceleration ramps, switching frequencies between 2 kHz and 16 kHz, and control mode selections such as V/f characteristic curves or sensorless vector control.
To duplicate parameters during unit replacement, the Keypad XT module can copy and transfer complete parameter files directly from one drive to another without requiring a PC connection. When using GDC software, saved project files can be uploaded and written to replacement units over a direct programming connection. If a replacement drive exhibits unexpected behavior or parameter corruption, restoring default factory settings via parameter C0002 prepares the unit for clean parameter transfer.
Communication and System Integration
The E82EV251_2C basic unit relies on replaceable function modules attached to its front interface slot to establish control connections and network protocols. Supported options include the Standard I/O Function Module (E82ZAFSC) for discrete terminal control, as well as dedicated communication modules such as CANopen (E82ZAFCC) and PROFIBUS-DP (E82ZAFPC). The drive also supports Interbus and DeviceNet function modules to integrate seamlessly into broader industrial automation architecture.
Communication integrity is continuously monitored by the drive hardware. If fieldbus communication drops or experiences network interruptions, the drive flags a process data monitoring fault (CE1). Addressing bus faults requires verifying module seating on the basic unit connector, checking network cabling and termination, and confirming node addressing and baud rate parameters match the master controller configuration.
Diagnostics and Status Indication
Real-time monitoring on the E82EV251_2C frequency inverter is provided through visual LED indicators and accessible memory registers. The drive features dual-color status LEDs that signal operational modes, warnings, and trip conditions. Further diagnostic evaluation can be conducted via the Keypad XT interface, parameter C0013 fault history memory, status register C0183, or the online diagnostic window in Global Drive Control software.
First-line troubleshooting should include checking DC bus voltage status, motor phase wiring, and function module attachment. Internal errors such as memory failure or EEPROM checksum corruption are indicated by a rapidly flashing red LED, signalling that parameter restoration or hardware servicing is required.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green LED | Green - Solid | Inverter operation enabled / drive running |
| Green LED | Green - Flashing slowly | Inverter inhibited (Inhibit active) |
| Red LED | Red - Flashing | Warning state active |
| Red LED | Red - Solid | Fault state active (Trip condition) |
| Red LED | Red - Flashing rapidly | Internal hardware error / EEPROM fault (Service or repair required) |
Replacement and Spare Part Considerations
When replacing a Lenze 8200 Vector drive model E82EV251_2C, the replacement unit must match the power output rating of 0.25 kW and supply voltage specifications of 180 to 264 V AC. Because the basic unit does not include built-in terminal blocks or fieldbus interfaces, the installed function module from the original drive—such as a Standard I/O or CANopen module—must be transferred directly to the replacement unit.
Before putting a spare drive into service, parameter configuration must be aligned with the machine's operating parameters. A blank or factory-default replacement unit will not operate correctly until the parameter set is transferred via Keypad XT or loaded using Global Drive Control software. Ensure that motor parameters, acceleration/deceleration times, and communication node settings are verified prior to starting motor operation.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|

Frequently Asked Questions
What software is used to program and configure the Lenze 13435816 E82EV251_2C drive?
The drive can be configured using Lenze Global Drive Control (GDC) software version 4.0 or higher and Lenze EASY Starter. Alternatively, parameters can be adjusted directly on the drive using the plug-in Keypad XT module (E82ZBC).
How do I transfer parameters from a failed drive to a replacement unit?
Parameters can be copied onto a Keypad XT plug-in module from the active drive and transferred directly into the replacement unit. Alternatively, parameter projects can be saved and downloaded using Global Drive Control software over a PC interface connection.
What does a rapidly flashing red LED on the E82EV251_2C inverter indicate?
A rapidly flashing red LED indicates an internal hardware error or EEPROM memory fault. You can attempt to clear the fault by restoring factory default settings via parameter C0002; if the fault persists, internal board repair or unit replacement is required.
Can the Lenze E82EV251_2C operate on both single-phase and three-phase supply lines?
Yes, the E82EV251_2C supports dual input voltage options across a 180 to 264 V AC range, operating on either a single-phase 230V AC or three-phase 230V AC power supply.
How do I clear a communication error fault code such as CE0 or CE1?
For CE0 (module communication fault), power down the drive and firmly re-seat the function module on the basic unit connector. For CE1 (fieldbus timeout), inspect network cabling, verify master PLC status, and confirm node address and baud rate parameter settings.
