Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13437162, designated by model number E82EV371_2C201, is a 0.37 kW (0.5 hp) frequency inverter belonging to the Lenze 8200 vector product family. Designed for precise speed and torque control of AC electric motors in industrial automation systems, this compact AC drive operates on a nominal 230 V AC supply across an allowable input voltage range of 180 V to 264 V AC at 45 to 65 Hz on either a 1-phase or 3-phase supply. The unit delivers a controlled 3-phase output voltage from 0 to 230 V AC, sustaining a continuous output current of 2.4 A at an 8 kHz carrier switching frequency and an output frequency range of 0 to 480 Hz. Featuring an IP20 protection class enclosure tailored for control cabinet mounting, the drive supports both standard V/f characteristic operation and sensorless vector control to maintain dynamic motor torque across varying speed requirements in conveyor systems, industrial pumps, fans, and packaging machinery.
Connecting and integrating a replacement E82EV371_2C201 unit into an existing machine requires matching the installed physical expansion hardware and drive parameters. The inverter features a modular internal expansion slot that accommodates optional plug-in function modules, including Standard I/O, Application I/O, or fieldbus communications such as CANopen (E82ZAFAC), PROFIBUS-DP (E82ZAFPC), or serial LECOM RS232/RS485 adapters. Commissioning a replacement unit is rarely a simple plug-and-run operation; parameter sets must be transferred to mirror the original drive's settings. The inverter stores up to four complete parameter sets in internal non-volatile EEPROM memory. Parameters can be cloned and uploaded using the optional Lenze XT Keypad (E82ZBC) or transferred via a PC connected to Lenze Global Drive Control (GDC) software. ABC Industrial Parts can support parameter extraction and configuration transfer when restoring replacement drives to production readiness.
System status and fault detection are managed through direct visual cues and software diagnostics. Two front-panel status LEDs provide immediate feedback: a green Operation LED indicates mains power connection and operating state, while a red Fault LED flags active error conditions. Detailed fault diagnostics are available as text descriptions on the XT Keypad display, stored in the drive's parameter C0161 fault history log, or monitored in real time via Lenze GDC software. Recorded fault codes cover specific operating issues such as overcurrent during acceleration (OC1), deceleration (OC2), or constant speed (OC5), DC bus overvoltage (OU) or undervoltage (LU), heatsink or motor overtemperature (OH, OH4, OH7), and earth faults (OC6). Initial field troubleshooting should verify input power quality, motor cable insulation resistance, motor loading, and proper seating of plug-in function modules. Internal circuit board failures, such as EEPROM memory corruption (EER) or internal hardware errors (H05), cannot be repaired in the field; obtaining a tested exchange unit or professional repair through ABC Industrial Parts provides a rapid solution to restore machine uptime.

Programming and Configuration
Parameterization and programming for the Lenze 13437162 inverter are handled through dedicated hardware interface options or software tools. The drive features non-volatile EEPROM memory capable of retaining up to four distinct parameter sets simultaneously. This multi-dataset architecture allows complex machine setups or alternative operational modes to be stored directly within the inverter without loss during power interruption. Re-commissioning or resetting a drive can be performed by restoring factory default settings using parameter C0002.
For hands-on parameter access, the optional XT Keypad E82ZBC attaches directly to the front of the drive, presenting clear-text parameter menus and fault code readings. Alternatively, Lenze Global Drive Control (GDC) PC software provides a full graphical commissioning environment. GDC allows engineers to edit parameters, upload and download configuration files, monitor real-time operating parameters, and perform parameter cloning across multiple drives to ensure identical setup in multi-axis machinery.
Communication and System Integration
The Lenze E82EV371_2C201 frequency inverter utilizes a flexible modular architecture for network and fieldbus connectivity. Rather than using fixed built-in fieldbus ports, the inverter includes an internal expansion slot designed to accept plug-in function modules. This modular structure allows the core drive unit to integrate seamlessly into diverse industrial automation architectures without altering the underlying inverter hardware.
Supported interface options include the CANopen function module E82ZAFAC, the PROFIBUS-DP function module E82ZAFPC, and LECOM serial communication interfaces for RS232 or RS485 networks. In addition to fieldbus adapters, the expansion slot accepts Standard I/O or Application I/O modules for discrete control wiring. Communication status and protocol-level link errors, such as function module communication fault CE0, are monitored by the drive to ensure reliable real-time control across automated conveyor systems, packaging equipment, and material handling lines.
Diagnostics and Status Indication
Real-time operational feedback for the Lenze 13437162 is delivered via two visual LED indicators located on the front panel. The green Operation LED indicates that input AC power is applied and reflects the active operational state of the drive through solid or flashing patterns. The red Fault LED illuminates or flashes to alert maintenance staff of active error states or trip conditions.
For comprehensive troubleshooting, the inverter logs historical fault events in parameter C0161. When fitted with the optional XT Keypad E82ZBC, the drive displays active fault codes and plain-text diagnostic messages. System diagnostics can also be performed via Lenze Global Drive Control (GDC) PC software, which displays live operating variables, bus voltages, output currents, and active fault registers for fast root-cause identification.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Operation | Green - Solid / Flashing | Indicates operating status and mains power connected |
| Fault | Red - Solid / Flashing | Indicates fault or active error condition |
Replacement and Spare Part Considerations
When replacing a failed Lenze 13437162 (E82EV371_2C201) frequency inverter, maintenance personnel must confirm that both the core drive specifications and the installed plug-in function module match the original installation. Because the base inverter is supplied without communication modules or keypads, any existing communication modules (such as CANopen E82ZAFAC or PROFIBUS-DP E82ZAFPC) must be unclipped from the failed unit and securely mounted into the replacement drive's expansion slot, taking care to check fixing screws to avoid module communication faults (CE0).
A replacement unit must be loaded with the parameter configuration of the original drive before being placed into active service. Parameters stored in the four EEPROM memory banks of the original drive can be transferred using the XT Keypad E82ZBC memory transfer function or saved and reloaded using Lenze Global Drive Control (GDC) software. If the original parameters cannot be read due to severe drive damage, parameters must be re-entered from machine documentation or donor backups.
Although the Lenze 8200 vector series has been officially discontinued by the manufacturer, direct replacement spare units remain essential for maintaining existing production equipment without undergoing costly panel rewiring or PLC program updates. For long-term modernization strategies, a migration path exists to the modern Lenze i510 or i550 cabinet series frequency inverters.
