Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E82EV302_2C is a 3.0 kW frequency inverter from the 8200 Vector product family, designed to provide precise speed and torque control for industrial three-phase AC motors. Operating across a supply voltage range of 180 to 264 V AC with a rated output voltage of 230 V AC, this compact IP20-rated drive supplies a continuous output current of 16.5 A at an 8 kHz switching frequency. To handle dynamic motor acceleration and heavy starting loads, it delivers a peak output current of 24.8 A for up to 60 seconds. The drive supports flexible motor control modes including sensorless vector control, standard V/f characteristic control, and torque control, operating over an output frequency range of 0 to 480 Hz. An integrated transistor brake chopper allows direct connection of an external braking resistor for demanding deceleration cycles.
Integrating a replacement unit into an existing machine requires matching communication interfaces and parameter configurations. The E82EV302_2C features a pluggable function module slot that accepts interchangeable fieldbus options, including E82ZAF series modules for CANopen, PROFIBUS-DP, DeviceNet, and Modbus RTU integration. Commissioning a spare drive does not require complex setup routines; full parameter sets can be cloned directly using the pluggable E82ZMC001 parameter memory module or adjusted using the E82ZBC XT Keypad and Lenze Global Drive Control (GDC) software. When replacing a failed unit, transferring the E82ZMC001 chip or uploading the parameter set ensures proper alignment of ramp times and motor data before restoring power. ABC Industrial Parts can assist maintenance teams with pre-tested replacement drives and parameter transfer requirements to minimize operational downtime.
System status and operating conditions are indicated locally via green and red status LEDs, where solid or flashing illumination signals operational readiness or fault conditions. Detailed diagnostics are accessible through the E82ZBC XT Keypad, which displays active fault codes alongside the C0168 history buffer, as well as via fieldbus status words or the GDC software diagnostic window. Fault conditions range from output short circuits (OC1) and earth faults (OC2) to DC bus overvoltage (OU), undervoltage (LU), or heatsink overtemperature (OH). While line power checks or parameter adjustments for ramp times (C0012, C0013) can resolve external issues, internal board failures such as EEPROM checksum corruption (EEr) or microprocessor self-test errors (H05) are not field-serviceable. In such cases, sourcing a refurbished unit or sending the drive to ABC Industrial Parts for professional repair provides a fast route back to production.

Programming and Configuration
Parameter management and drive configuration for the Lenze E82EV302_2C frequency inverter are supported through hardware keypads and PC software tools. Drive parameters can be adjusted directly at the unit using the optional E82ZBC XT Keypad, which provides menu navigation and real-time monitoring. For systematic commissioning, offline parameter storage, and detailed axis diagnostic windows, Lenze Global Drive Control (GDC) software connects directly to the drive to configure motor data, dynamic speed control loops, and specialized I/O assignments.
The drive includes a dedicated slot for the pluggable E82ZMC001 parameter memory module. This EEPROM chip stores the complete operational parameter set of the inverter, allowing rapid parameter transfer without a computer connection. Swapping the E82ZMC001 module from a failed drive into a replacement unit instantly copies all acceleration ramps (C0012), deceleration times (C0013), speed limits (C0011), and application-specific settings. If a complete drive reconfiguration is necessary, reloading factory default settings is executed by setting parameter C0002 to 1.
Communication and System Integration
The Lenze E82EV302_2C features a modular communication architecture that accepts interchangeable function modules in its pluggable slot. By selecting appropriate E82ZAF series communication modules, the drive integrates into fieldbus systems including CANopen, PROFIBUS-DP, DeviceNet, and Modbus RTU. These modules enable cyclic process data exchange, remote speed demand references, and operational control from a central PLC.
Continuous network monitoring is handled via fieldbus status words and timeout supervision routines. If communication between the master controller and the pluggable module is interrupted, the inverter generates a CE0 communication fault. Restoring system communication requires checking cable integrity, verifying proper line termination, and confirming the master controller operational state.
Diagnostics and Status Indication
The Lenze E82EV302_2C frequency inverter features red and green status LEDs on its front panel to provide instant status indication. The green LED signals readiness and active operation, remaining illuminated during normal run states and flashing during status transitions. The red LED illuminates solid or flashes when a fault or drive error condition is detected, providing an immediate visual signal during tripping events.
For technical fault analysis, operators can inspect active fault codes on the E82ZBC XT Keypad display or review historical diagnostic entries saved in the C0168 history buffer. Diagnostic data and active status words can also be read across fieldbus networks or viewed within the diagnostic window of Lenze Global Drive Control (GDC) software.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Red LED | Red - Solid/Flashing | Fault/Error indicator |
| Green LED | Green - Solid/Flashing | Operation/Ready indicator |
Replacement and Spare Part Considerations
Replacing a Lenze E82EV302_2C inverter requires matching key electrical characteristics prior to powering up the system. Ensure the replacement drive matches the required 180 to 264 V AC supply voltage range and 3.0 kW output rating (16.5 A continuous current). Verify that any installed communication option, such as an E82ZAF series module for PROFIBUS or CANopen, is correctly seated in the replacement unit's function module slot.
Transferring parameter configurations from the old drive to the spare unit is necessary to ensure consistent operation. If the original inverter contains an E82ZMC001 parameter memory chip, moving this module to the replacement drive transfers all acceleration ramps, motor parameters, and fieldbus settings without using external programming devices. If the memory module cannot be reused, parameter files saved via Lenze Global Drive Control (GDC) software or configured manually with the E82ZBC XT Keypad must be loaded into the replacement.
Before restoring production power, inspect all field wiring, including AC input supply lines, motor phase leads, braking resistor connections, and fieldbus cables. In events where a drive failure is triggered by internal hardware errors such as an EEr EEPROM checksum fault or H05 board component breakdown, internal repairs are not possible on-site. Replacing the inverter with a tested spare or sending the damaged unit for professional repair offers the safest path to restore operational uptime.

Frequently Asked Questions
How can parameters be transferred to a replacement Lenze E82EV302_2C inverter?
Parameters can be transferred without a PC by swapping the pluggable E82ZMC001 parameter memory module from the original drive into the replacement unit. Alternatively, parameter sets can be uploaded using Lenze Global Drive Control (GDC) software or manually entered using the E82ZBC XT Keypad.
Which fieldbus protocols are supported by the E82EV302_2C inverter?
The E82EV302_2C supports CANopen, PROFIBUS-DP, DeviceNet, and Modbus RTU through interchangeable E82ZAF series pluggable communication modules.
What do the red and green status LEDs indicate on the inverter?
The green LED indicates operational readiness and normal drive operation. The red LED illuminates solid or flashes when a fault condition or error event is detected.
What causes an OU fault code and how is it resolved?
An OU fault code indicates DC bus overvoltage, usually caused by motor energy regeneration during stopping or an excessively short deceleration time. To resolve it, extend the deceleration ramp time via parameter C0013 or connect an external braking resistor to the internal brake chopper.
How do I reset the E82EV302_2C inverter to its factory default parameters?
To reset the drive to factory defaults, set parameter C0002 to 1 using either the E82ZBC XT Keypad or Lenze Global Drive Control (GDC) software.
