Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E82EV371_2C is a compact 0.37 kW (0.5 HP) frequency inverter within the 8200 Vector drive series. Built for regulating standard three-phase AC asynchronous motors, this variable frequency drive operates on a nominal 230 V AC supply, accommodating single-phase input from 180 to 264 V AC and three-phase input from 100 to 264 V AC. The inverter provides a rated continuous output current of 2.4 A with a 150% overload capacity of 3.6 A for up to 60 seconds. Operating via selectable sensorless vector control or adjustable V/f linear curves, it delivers controlled speed and full torque performance across industrial machinery including belt conveyors, centrifugal pumps, fans, and packaging feed equipment.
Putting a replacement E82EV371_2C unit into service relies on matching the modular hardware configuration and parameter settings of the original drive. The inverter utilizes pluggable control terminals and an interchangeable function module slot to support fieldbus connectivity through options like the CAN System Bus module E82ZAFCC, PROFIBUS-DP module E82ZAFPC, or Serial Interface module E82ZAFXC. Parameter cloning and project adjustments are carried out using the optional XT Keypad EMZ8201BB or Global Drive Control (GDC) PC software. Because a replacement drive contains default parameters, transferring operating configurations from internal non-volatile EEPROM storage or a saved project file is necessary prior to motor operation. ABC Industrial Parts supports maintenance technicians with replacement units and guidance for backing up and transferring drive parameter profiles.
Drive status and fault conditions are monitored on the front face of the E82EV371_2C using a dedicated multi-state STATUS LED. A solid green light indicates normal enabled operation, a flashing green light shows that the inverter is ready with controller inhibit active, and a solid red light flags a trip or fault condition. Detailed diagnostic trip codes and fault history registers (C0168) can be reviewed using the XT Keypad or GDC monitor. Common operational trips include OC1 short circuit, OC2 overcurrent during acceleration, OU DC bus overvoltage, and LU DC bus undervoltage. When non-volatile EE memory corruption or H05 internal hardware self-test failures occur, the internal electronics cannot be serviced in the field. Sourcing a tested exchange drive or utilizing professional repair options through ABC Industrial Parts ensures a reliable return to production.

Programming and Configuration
Drive setup and parameter adjustment for the Lenze E82EV371_2C are managed using the Global Drive Control (GDC) PC software package or the detachable XT Keypad EMZ8201BB. Non-volatile EEPROM storage inside the drive maintains configuration parameters when control power is removed. Key parameters controlling drive performance include maximum motor speed (C0011), acceleration ramp time (C0012), and deceleration ramp time (C0013).
When commissioning a replacement inverter, parameter configurations can be cloned directly from an existing unit using the XT Keypad parameter copy function or downloaded via a GDC project file. If parameter memory becomes invalid or requires resetting during setup, setting parameter code C0002 to 1 restores the drive to factory default values. Correct alignment of motor limits, switching frequency (2 to 16 kHz), and vector control parameters ensures stable dynamic performance.
Communication and System Integration
The modular hardware design of the Lenze 8200 Vector E82EV371_2C enables integration into diverse automated system architectures. The drive base unit features pluggable control terminals for basic wired control signals and a dedicated option bay for attaching plug-in communication modules.
Available interface modules include the System Bus CAN Function Module E82ZAFCC for CANopen interaction, the PROFIBUS-DP Function Module E82ZAFPC for fieldbus connection to master controllers, and the Serial Interface Module E82ZAFXC. Ensuring that function modules are fully seated and that bus termination resistors are correctly installed prevents fieldbus interruption faults such as CE0 communication errors.
Diagnostics and Status Indication
Visual status indication on the E82EV371_2C drive is provided by a multi-color STATUS LED located on the unit front panel. The LED provides immediate feedback regarding operational status, controller inhibit conditions, and fault trip states.
In-depth diagnostic capabilities are provided by the internal fault history memory register (C0168), which logs historic fault events. Diagnostic data can be read directly in clear text via the XT Keypad EMZ8201BB display or monitored in real time using the diagnostic interface in Global Drive Control (GDC) software.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| STATUS LED | Green - Solid | Inverter enabled and running normally |
| STATUS LED | Green - Flashing | Inverter ready for operation, controller inhibit active |
| STATUS LED | Red - Solid | Inverter in trip or fault state; operational inhibit active |
Replacement and Spare Part Considerations
When selecting a spare for an installed Lenze E82EV371_2C frequency inverter, verify that the replacement match spans both the base unit part number and the attached option modules. Because the 8200 Vector architecture separates the power stage from communication interfaces, existing option modules such as the E82ZAFCC CAN or E82ZAFPC PROFIBUS modules must be transferred to the replacement drive base.
A replacement drive unit will not operate correctly until programmed with the machine's specific operating parameters. Parameters can be cloned from a functioning unit using the XT Keypad EMZ8201BB or loaded via Global Drive Control (GDC) software. In cases where the original drive suffered an EE memory corruption or H05 internal hardware fault, settings must be re-entered manually or loaded from documented site backups.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| OC1 | Short Circuit | Short circuit on motor phase output terminals or severe earth fault. | Short circuit in motor cable or motor winding, motor lead capacitance too high, excessive acceleration rate. | Check motor and output cabling for phase-to-phase or phase-to-earth short circuits. Increase acceleration time (C0012). |
| OC2 | Acceleration Overcurrent | Instantaneous current limit exceeded during acceleration ramp. | Acceleration time set too short, motor incorrectly dimensioned, mechanical jam or overload. | Extend acceleration ramp time (C0012), check mechanical drive load for binding. |
| OC5 | I x t Overload | Inverter thermal load limit (I x t protection) exceeded. | Continuous operation above rated output current, low motor speed under high load without forced cooling. | Reduce continuous mechanical motor load, verify inverter current sizing. |
| OU | Overvoltage DC Bus | DC bus voltage exceeded upper threshold (approx. 400 V DC for 230V units). | Regenerative energy from driven mass during deceleration is too high, deceleration ramp time too short. | Extend deceleration time ramp (C0013), connect optional braking module/resistor if installed. |
| LU | Undervoltage DC Bus | DC bus voltage dropped below minimum threshold during operation. | Mains supply voltage too low, mains phase failure, high momentary mains voltage dip. | Check mains input line voltage and phase balance. |
| OH | Heatsink Overtemperature | Inverter heatsink temperature exceeds maximum safety limit. | Insufficient cooling airflow, ambient temperature too high, dirty heatsink cooling fins, cabinet fan failure. | Improve enclosure ventilation, clean heatsink fins, check ambient operating temperature. |
| OH4 | Motor Over-Temperature | Motor temperature sensor (PTC/thermal contact) detected thermal overload. | Motor thermal overload, cooling fan failure on motor, PTC circuit interrupted. | Allow motor to cool down, check motor ventilation and PTC sensor wiring connection. |
| EE | EEPROM Memory Error | Internal non-volatile memory corruption or read/write error during operation. | Interrupted parameter saving process, internal hardware component failure. | Reset parameters to factory defaults (C0002 = 1). If fault persists, internal hardware error — return unit for repair or replace. |
| CE0 | Communication Error 0 | Communication fault on external system bus / function module interface. | Function module dislodged, cable fault, termination resistor missing, fieldbus master timeout. | Check physical seating of function module, verify fieldbus wiring and bus termination resistors. |
| H05 | Internal Hardware Error | Internal self-test failed during initialization or control board hardware defect. | Internal circuit board failure, corrupted internal system firmware. | Internal hardware fault — power cycle unit; if persistent, unit is not field-serviceable and must be replaced. |
| NMAX | Speed Limit Exceeded | Actual motor speed exceeded maximum configured speed threshold. | Overhauling load driving motor faster than maximum output frequency setting. | Check motor parameter settings (C0011) and mechanical load dynamics. |
