Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13141964 E82EV402_4C is an IP20 panel-mounted frequency inverter from the 8200 Vector series, engineered to control speed and torque in three-phase AC induction motors. Rated for a nominal output power of 4.0 kW (5.5 HP) at 400/480 V AC, this compact AC drive supports wide three-phase input voltage ranges from 320 V AC to 528 V AC. Designed for mounting inside control cabinets, the drive provides motor regulation using sensorless vector control for high-torque applications or customizable V/f control characteristics for standard pump, fan, and conveyor equipment. It delivers a continuous output current of 9.5 A at 400 V and 7.9 A at 480 V, with peak overload capacity reaching up to 14.3 A for 60 seconds.
Modular architecture allows the E82EV402_4C to interface with various industrial automation setups via interchangeable communication and application options. The unit accepts plug-in function modules such as the E82ZAFPC PROFIBUS module and E82ZAFCC CANopen module, as well as optional interfaces for DeviceNet, Modbus RTU, and INTERBUS. Commissioning a replacement unit requires transferring the parameter profiles, which are saved across four non-volatile internal memory slots. Parameter transfer can be accomplished using the XT Keypad E82ZBC, the plug-in E82ZMC050 memory module, or Lenze Global Drive Control (GDC) PC software. Facilities seeking to restore equipment quickly can rely on ABC Industrial Parts for pre-tested spare drives and parameter backup support.
System diagnostics are communicated through a dual-color STATUS / FAULT LED on the front panel alongside fieldbus status words and fault code logs stored under parameter C0168, readable via GDC software or the XT keypad. Trip condition codes identify operational issues such as motor terminal short circuits (OC1), DC bus overvoltage (OU), and supply phase loss (LU or LP1), which can often be resolved by inspecting line fuses, wiring, or braking resistors. Internal hardware failures, including power section errors (P13), control board logic faults (H05), or EEPROM corruption (EER), represent board-level faults that are not field-serviceable. When hardware failures stop production, selecting a replacement or tested exchange unit through ABC Industrial Parts provides a dependable path back to operational service.

Programming and Configuration
Programming and commissioning for the Lenze 13141964 E82EV402_4C inverter are executed through Lenze Global Drive Control (GDC) software or manually using the optional XT Keypad E82ZBC. The drive internal memory integrates non-volatile storage capable of holding up to four complete parameter sets. This capability allows technicians to store multiple machine setups or motor operating curves within a single inverter and activate them dynamically using digital inputs or serial communication commands.
When commissioning a spare unit, matching the original drive parameterization is critical for motor protection and machine timing. Parameter profiles can be cloned off-line or on the factory floor using the E82ZMC050 memory module, which plugs directly into the drive module slot. Alternatively, connecting a PC via GDC software allows full parameter modification, including setting acceleration times (C0012), deceleration times (C0013), and switching frequency adjustments up to 16 kHz for low-noise motor operation.
Communication and System Integration
The 8200 Vector series separates system communication functions from the main power inverter. The E82EV402_4C base unit utilizes interchangeable function modules that plug into the front interface slot, enabling connection to higher-level automation controllers. Supported modules include the E82ZAFPC interface for PROFIBUS-DP networks and the E82ZAFCC interface for CANopen fieldbuses, along with plug-in options for DeviceNet, Modbus RTU, and INTERBUS.
Integrating the inverter into a fieldbus architecture allows real-time control over drive start/stop signals, velocity setpoints, and operational feedback. The fieldbus link enables real-time access to drive status words, active output current levels, and internal fault diagnostics. For applications using discrete control logic, terminal connections on the plugged function modules provide standard analog and digital control inputs alongside network interfaces.
Diagnostics and Status Indication
Operational monitoring for the Lenze E82EV402_4C is provided via front-panel LED indicators, fieldbus status words, and internal memory logs. The drive includes a dual-color STATUS / FAULT LED that communicates active operating states, readiness status, and trip conditions. Diagnostic parameters such as C0168 retain a history of active and past fault codes, which can be read using an attached XT Keypad E82ZBC or through the Global Drive Control software environment.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| STATUS / FAULT | Red / Green - Solid / Flashing | Indicates active operating state, drive readiness, or specific fault condition |
Replacement and Spare Part Considerations
When replacing an existing Lenze E82EV402_4C, verify both the power section specifications and the installed modular options. The IP20 unit requires cabinet panel mounting with adequate clearance to allow unrestricted airflow across the heatsink fins. The input power requirements (320-528 V AC 3-phase) and rated motor capacities (4.0 kW at 400 V / 5.5 HP at 480 V) must match the existing mechanical load to ensure continuous operation without triggering I x t overload trip conditions (OC5).
Because the E82EV402_4C is supplied as a modular base drive, the installed communication or application module—such as an E82ZAFPC PROFIBUS or E82ZAFCC CANopen card—must be transferred to the replacement chassis. Before energizing the motor, restore the stored configuration using an E82ZMC050 memory module, an XT Keypad, or a saved GDC parameter file. For modernizing system architectures, the Lenze i550 Cabinet Inverter (model i55AE240F) is available as the recommended successor model.
