Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00356372, designated by model type 33.8203_E, is a 3-phase AC frequency inverter power module from the Lenze 8200 Series. Designed for speed and torque regulation of 3.0 kW AC motors, this drive operates on a nominal 400 V AC supply with an extended input tolerance from 320 V to 550 V AC. It provides an 8 A mains input current rating, a continuous output current of 7.3 A across an output voltage range of 0 to 400 V AC, and an output frequency range up to 480 Hz. Housed in an IP20 enclosure, the unit features selectable switching frequencies between 2 kHz and 16 kHz with an 8 kHz default rating to balance performance and acoustic motor noise.
Built around a modular architecture, the 33.8203_E power module integrates with external control components and fieldbus networks via plug-in modules. Supported communication interfaces include PROFIBUS-DP using the EMF2133IB module, CANopen via EMF2171IB or EMF2172IB, and LECOM RS232/RS485 using the EMF2102IB module. Commissioning and parameter assignment can be performed using an EMZ2101 or EMZ2102 operating keypad or through Lenze Global Drive Control (GDC) PC software. To simplify field replacements, configuration data and parameter sets are stored in non-volatile internal EEPROM memory, allowing parameters to be extracted and loaded into a replacement unit without reconfiguring system logic from scratch. Expert support from ABC Industrial Parts can assist when transferring drive profiles or restoring configurations during maintenance.
Diagnostic conditions are communicated directly via front-panel status LEDs and keypad diagnostic views. A green LED indicates controller enabling or standby, while a red LED signals active TRIP faults, warnings, or locked states. System status and active fault history are logged in parameter C0161, with current fault codes visible in keypad parameter C0003 or through GDC software. The drive monitors critical conditions such as overcurrent (OC1, OC2, OC5), overvoltage (OU), undervoltage (LU), mains phase loss (LP1), and heatsink overtemperature (OH). When parameter memory errors (Pr1) or internal hardware failures (H05) occur, initial troubleshooting involves re-loading default parameter sets. Internal hardware errors indicate board-level component failures that cannot be repaired in the field, making unit repair or a fully tested exchange drive from ABC Industrial Parts the fastest path to restoring production.

Programming and Configuration
Configuration of the Lenze 00356372 inverter is carried out using Lenze Global Drive Control (GDC) PC software or an attached EMZ2101 / EMZ2102 operating keypad. Operating parameters control motor limits, acceleration/deceleration ramps, switching frequency selections, and fieldbus node parameters. Parameter C0003 displays active fault codes directly on the keypad screen, while parameter C0161 stores the historical fault log.
The inverter contains internal non-volatile EEPROM memory capable of backing up dual parameter sets. This capability allows operators to store a complete backup profile on the unit or copy parameter settings directly to an EMZ2101 or EMZ2102 keypad. When installing a replacement power unit, stored parameters can be reloaded without requiring a full re-commissioning procedure.
Communication and System Integration
The 33.8203_E power base unit relies on plug-in communication modules to integrate into industrial control architectures. For PROFIBUS-DP network connectivity, the unit pairs with the EMF2133IB communication module. For CANopen networks, the drive supports the EMF2171IB and EMF2172IB modules, enabling rapid transfer of process data and control words.
For point-to-point serial communication or legacy system connections, the EMF2102IB LECOM module provides RS232 or RS485 physical interfaces. These modular options allow the same core 3 kW frequency inverter to be deployed across distinct automation platforms without altering the base power hardware.
Diagnostics and Status Indication
The Lenze 00356372 incorporates real-time diagnostic features via front panel LEDs, parameter readouts, and software monitoring. Visual feedback is provided by two LEDs located on the unit interface. Parameter C0161 records active and historical diagnostic messages, allowing technicians to trace intermittent tripping events or grid instability.
Advanced diagnostic views are accessible by connecting the drive to Global Drive Control (GDC) software or attaching an EMZ2101/EMZ2102 keypad. These tools allow real-time monitoring of DC bus voltage, output current, heatsink temperature, and fieldbus communication timing.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green LED (Operation / Ready) | Green - Solid / Blinking | Solid ON: Controller enabled / normal operation. Blinking: Controller inhibit (IMP) / standby. |
| Red LED (Fault / TRIP) | Red - Solid / Blinking / Off | Solid ON: TRIP fault active. Blinking: Warning or locked condition active. OFF: No fault. |
Replacement and Spare Part Considerations
When replacing a Lenze 00356372 (33.8203_E) frequency inverter, confirm that the replacement matches the rated motor power (3.0 kW) and supply voltage requirements (400V 3-phase). The plug-in fieldbus option module and operating keypad from the original unit must be transferred to the replacement unit if identical communication protocols are required.
Before placing a spare drive into operation, parameter settings must be aligned with the machine specifications. Parameter sets saved on an EMZ2101/EMZ2102 keypad or backed up via Global Drive Control (GDC) software should be downloaded to the replacement unit. Standard factory drives are delivered with default parameters and will not operate correctly until motor parameters and bus addresses are transferred.
If the existing drive exhibits hardware faults such as error code H05, board-level components cannot be serviced on site. In these instances, swapping the unit with a fully tested spare or sending the faulty drive for professional repair is necessary to restore equipment operation.
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 / Overcurrent during Acceleration | Output current exceeded overcurrent threshold during acceleration ramp. | Short circuit or ground fault at motor terminals, motor cable too long, acceleration ramp too short. | Check motor wiring and isolation; extend acceleration time; check motor size against drive rating. |
| OC2 | Short Circuit / Overcurrent during Deceleration | Output current exceeded overcurrent threshold during deceleration ramp. | Deceleration ramp time too short, short circuit on output. | Extend deceleration time, fit braking module/resistor if necessary, check motor cables. |
| OC5 | Overload / Overcurrent during Constant Operation | Continuous motor overload or mechanical blockage during steady state operation. | Mechanical blockage, drive under-dimensioned, severe load fluctuation. | Check mechanical load for binding; verify motor/inverter sizing. |
| OU | Overvoltage in DC Bus | DC bus voltage exceeded upper limit. | Regenerative energy from motor during deceleration is too high, mains voltage too high. | Increase deceleration time, check mains voltage, connect brake transistor/resistor. |
| LU | Undervoltage in DC Bus | DC bus voltage dropped below minimum operating limit. | Mains supply failure, voltage drop under load, weak mains supply. | Check mains voltage and supply line fuse connection. |
| OH | Heatsink Overtemperature | Heatsink temperature exceeded allowable maximum threshold (~85-90°C). | Insufficient cooling airflow, ambient temperature too high, clogged heatsink fins, fan failure. | Clean heatsink, ensure adequate cabinet ventilation, lower switching frequency or load. |
| OH4 | Motor Overtemperature | Motor thermistor/PTC sensor triggered high temperature alarm. | Motor thermal overload, insufficient motor cooling at low speeds. | Allow motor to cool down, inspect forced cooling fan on motor, reduce load. |
| LP1 | Mains Phase Failure | Phase loss detected on AC main input. | Loose supply wire, blown input fuse, unbalanced mains phases. | Check 3-phase AC input supply lines, fuses, and connections. |
| Pr1 | Parameter Error / EEPROM Fault | Data corruption detected in internal parameter storage. | Power interrupted during parameter saving, corrupted non-volatile memory. | Re-load factory default settings or reload parameter set from keypad/GDC. If error persists, hardware fault requires unit replacement. |
