Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13141986, model E82EV752_4C240, is a 7.5 kW frequency inverter belonging to the Lenze 8200 Vector drive series. Designed for panel mounting inside control cabinets with an IP20 enclosure rating, this 3-phase AC motor controller operates across an input voltage range of 320 to 528 V AC. The drive delivers a continuous rated output current of 16.5 A at a default switching frequency of 8 kHz, providing precise motor speed regulation across an output frequency range of 0 to 480 Hz. Supporting both sensorless vector control and standard V/f characteristic control, it is commonly applied in material handling conveyors, industrial pumps, fans, and packaging machinery.
Integrating the E82EV752_4C240 into a machine control system relies on its modular expansion architecture, featuring a dedicated extension slot that hosts plug-in function modules for fieldbus networking or tailored control terminal I/O. Putting a replacement drive into service is rarely a direct plug-and-play operation; the internal non-volatile EEPROM retains up to four switchable parameter sets that must match the specific machine operation. Parameter sets can be backed up and transferred using the Lenze XT Keypad E82ZBC001 or Global Drive Control (GDC) PC software. When replacing a damaged unit, parameter extraction or module transfer can be facilitated with technical support from ABC Industrial Parts to ensure identical drive behavior prior to system power-up.
Operational monitoring and fault diagnosis are handled via the front panel Ready/Fault bicolor LED indicator, as well as live diagnostic registers on the optional XT Keypad or GDC PC interface. The inverter continuously monitors input phase stability, DC bus voltage levels, output currents, and thermal limits to safeguard connected equipment. Initial troubleshooting should involve verifying three-phase AC power stability, motor winding insulation, control wiring connections, and parameter set selection. Persistent red fault conditions after cycling power or internal memory hardware errors indicate board-level issues, where securing a tested exchange unit or professional repair through ABC Industrial Parts offers a dependable path to restoring production.

Programming and Configuration
Configuring the Lenze 13141986 E82EV752_4C240 frequency inverter is accomplished using Lenze Global Drive Control (GDC) PC software or directly on the machine via the pluggable Lenze XT Keypad (E82ZBC001). The drive contains onboard non-volatile EEPROM memory capable of storing four distinct, switchable parameter sets. These internal parameter sets allow rapid adaptation to changing process requirements, enabling parameter adjustments for speed, acceleration, or torque limits without requiring continuous external reprogramming.
When commissioning a replacement inverter, parameter transfer is required to align motor nameplate data, acceleration curves, and I/O configurations. Using GDC software connected to the inverter, technicians can upload stored parameter configurations from an active or donor drive, edit parameters offline, and write the dataset to the replacement unit. If PC tools are not available on the shop floor, the XT Keypad can read and store the active parameter set from the original unit and download it directly into the spare inverter.
Communication and System Integration
The Lenze E82EV752_4C240 uses a flexible modular hardware structure centered on the base inverter and an extension slot. Fieldbus networking and tailored control terminal I/O are achieved by mounting interchangeable plug-in function modules into this slot. Compatible function modules include the E82ZAFCC, E82ZAFPC, and E82ZAFAC, enabling integration into fieldbus networks such as CANopen, PROFIBUS-DP, and Modbus RTU (LECOM).
Integrating a replacement drive into an existing control network requires matching both the hardware module and its communication settings to the higher-level PLC. Communication baud rates, station node addresses, and termination resistor settings are configured via DIP switches or internal parameter registers on the plug-in module. When replacing an inverter, the original function module should be transferred to the replacement drive chassis to maintain physical and protocol connectivity.
Diagnostics and Status Indication
Visual operational status on the Lenze E82EV752_4C240 drive is indicated by a front-mounted dual-color Ready / Fault LED indicator. Detailed operating data, active trip states, and historical error logs are retrievable through the XT Keypad E82ZBC001 diagnostic menu or via real-time monitoring registers in Lenze Global Drive Control (GDC) software.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Ready / Fault LED | Green / Red - Green flashing / Red solid or flashing | Green flashing indicates drive operational / ready state. Red solid or flashing indicates a drive fault or trip condition. A red indication persisting after a power cycle signals an internal hardware fault. |
Replacement and Spare Part Considerations
Replacing a Lenze 13141986 E82EV752_4C240 drive requires matching the 7.5 kW power rating, 16.5 A continuous current output, and 320 to 528 V AC 3-phase input voltage. Because base 8200 Vector drives do not include integrated communication interfaces, the original plug-in function module (such as E82ZAFCC, E82ZAFPC, or E82ZAFAC) must be removed from the failed inverter and installed into the replacement drive chassis.
Before putting a spare unit into operation, parameter settings must be loaded into the replacement drive's EEPROM. Standard default settings will not match application-specific acceleration rates, motor currents, or fieldbus configurations. Parameters can be copied using the XT Keypad E82ZBC001 or transferred via Global Drive Control PC software. For long-term equipment planning, Lenze recommends the i550 Cabinet Drive Series as the successor family for legacy 8200 Vector installations.
