Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 358056 frequency inverter, model designation 33.8201BB, is part of the Lenze 8200 series designed for variable speed control of standard three-phase AC induction motors. Operating with a rated power output of 0.37 kW (0.5 HP) and a continuous output current rating of 2.4 A, this motor drive accepts flexible supply configurations including single-phase 230 V AC and three-phase 230 V AC within an operating range of 180 V to 264 V AC. Built in an open IP20 enclosure suitable for control panel DIN rail or surface mounting, the unit utilizes V/f characteristic control with linear or quadratic profiles, delivering output frequencies from 0 Hz up to 480 Hz at a default switching frequency of 8 kHz.
For machine wiring and system integration, the unit provides four programmable digital inputs, one multi-range analog setpoint channel (0–10 V, 0–20 mA, or 4–20 mA), a digital status output, and a programmable fault relay for TRIP signaling. Putting a spare unit into service requires transferring configuration parameters, which can be accomplished using the removable EMZ2101 or E82ZBC operating keypad memory or via Lenze Global Drive Control (GDC) software. Commissioning a replacement unit involves matching optional snap-on fieldbus modules such as CANopen or PROFIBUS-DP and verifying input voltage line connections. When maintaining control cabinets with legacy components, technical support from ABC Industrial Parts helps ensure parameter transfer and hardware compatibility are managed accurately.
Local status diagnosis is provided by front-panel LEDs, including a solid green READY LED for normal operation and a red TRIP LED indicating fault conditions. Detailed error logs can be retrieved from parameter C0161 TRIP memory or viewed directly on an attached keypad display. Faults such as short circuits (OC1), ground faults (OC2), or DC bus overvoltage (OU) typically stem from motor wiring issues, excessive load, or short deceleration ramps. If internal hardware faults (H05) or EEPROM errors (EE0) occur on the control board, internal components are not field-serviceable, and sourcing a pre-tested replacement unit or repair through ABC Industrial Parts provides the fastest path to restore operations.

Programming and Configuration
Parameterization and commissioning of the Lenze 358056 drive are executed through Lenze Global Drive Control (GDC) engineering software or directly using the detachable EMZ2101 operating keypad. Operating parameters regulate essential drive functions including acceleration ramps (C0012), deceleration ramps (C0013), and V/f characteristic curve adjustments.
The optional plug-in operating keypad features built-in memory capable of backing up complete drive parameter sets. This feature allows technicians to copy configuration files from an operational unit and write them directly into a spare unit. Alternatively, GDC software enables offline project file storage, real-time monitoring, and complete parameter restoration across LECOM serial connections.
Communication and System Integration
The modular architecture of the Lenze 8200 platform supports flexible network integration through optional snap-on communication modules. The 358056 frequency inverter supports fieldbus cards for CANopen, PROFIBUS-DP, and Lenze LECOM (RS232/RS485) interface standards, allowing smooth integration into centralized PLC architectures.
On-board control interfaces include four programmable digital inputs and one multi-range analog setpoint input supporting 0–10 V, 0–20 mA, and 4–20 mA modes. System status outputs include a digital transistor output alongside a dedicated programmable TRIP relay contact for signaling fault states to external control systems.
Diagnostics and Status Indication
Local operational state indication on the Lenze 358056 is provided by two front-panel LED indicators. A solid green READY LED confirms power supply and normal operational status, while a solid or flashing red TRIP LED highlights active system faults or shutdown conditions.
Detailed troubleshooting is supported through the EMZ2101 keypad display or software diagnostic tools. The drive maintains a history buffer in parameter code C0161, recording recent TRIP fault codes to assist technicians in diagnosing intermittent supply dips, thermal overloads, or network timeouts.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| READY | Green - Solid | Operation / Ready state indicator |
| TRIP | Red - Solid / Flashing | TRIP active / Fault indication |
Replacement and Spare Part Considerations
When installing a replacement Lenze 358056 (33.8201BB) inverter into an existing control cabinet, form factor and line supply requirements must be confirmed. The IP20 chassis design matches the standard physical mounting and terminal locations of the Lenze 8200 series. Line supply connections must be checked to ensure input voltage remains within the allowed 180 V to 264 V AC range for 1-phase or 3-phase systems.
To avoid operational mismatch, identical parameter values must be loaded into the spare drive prior to driving the AC motor. Parameters can be rapidly cloned from an existing drive using the plug-in keypad memory or downloaded from a saved GDC project file. If the original installation utilizes fieldbus communications (such as CANopen or PROFIBUS-DP), the snap-on communication module from the original drive must be seated securely onto the replacement unit.
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 output motor terminals or internal transistor switch fault. | Short circuit in motor winding or motor cable, severe capacitive leakage, internal drive power stage short. | Check motor cable and winding insulation. If fault occurs immediately upon power up without motor connected, internal power module is defective requiring drive replacement or repair. |
| OC2 | Earth Fault | Ground fault / Earth fault detected on output phase. | Motor winding grounded to frame, damaged motor cable insulation, excessive cable length. | Check motor and wiring with megohmmeter. Replace defective wiring or motor. |
| OC5 | Overload during Acceleration | Excessive motor current draw during acceleration profile. | Acceleration time too short, mechanical overload, motor stalled. | Increase acceleration time (C0012), check mechanical drive train for binding. |
| OU | DC Bus Overvoltage | Intermediate circuit DC bus voltage exceeded upper limit. | Regenerative energy from motor during deceleration too high, deceleration ramp too short, line supply voltage too high. | Increase deceleration time ramp (C0013), fit external brake chopper / brake resistor if supported. |
| LU | DC Bus Undervoltage | Intermediate circuit DC bus voltage dropped below minimum threshold. | Mains voltage supply failure, voltage dip, mains fuse blown, internal pre-charge circuit fault. | Check main power line voltage supply, check input fuses and wiring. |
| OH | Heatsink Overtemperature | Drive heatsink temperature exceeded upper thermal trip limit. | Inadequate ventilation, clogged cooling fins, ambient temperature too high, fan failure. | Clean heatsink cooling fins, improve panel ventilation, allow unit to cool. |
| OH4 | Motor Overtemperature | Motor thermal sensor input triggered (PTC / thermal contact). | Motor overloaded, insufficient motor cooling at low speeds. | Allow motor to cool down, reduce load or check forced cooling fan. |
| CE0 | Communication Error | Interruption in fieldbus / automation module communication. | Loose cable, disconnected bus connector, baud rate mismatch, faulty communication module. | Check fieldbus cable connections, termination resistors, and module seating. |
| EE0 | EEPROM Fault | Data corruption or read/write error in internal parameter memory. | Electromagnetic interference during parameter write, hardware internal flash/EEPROM fault. | Restore factory default settings and reload parameter set. If fault persists, hardware board failure requires replacement. |
| H05 | Internal Hardware Error | Internal micro-controller or circuit fault detected during self-test. | Internal component failure, control board fault. | Internal hardware fault — power cycle unit. If problem persists, return unit for repair or replace. |
