Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00461758 ESMD222X2TXA is a 2.2 kW (3 HP) frequency inverter from the Lenze smd product family. Designed for precise motor speed control in automated machinery, this 3-phase drive operates across a nominal supply voltage range of 400 V AC to 480 V AC (320 to 528 V AC operating limits) at 48 to 62 Hz. Housed in a compact IP20 enclosure, the unit integrates a front-panel 3-digit LED display and programming keypad, delivering linear or quadratic V/f characteristic control for demanding industrial loads.
For machine integration and field wiring, the drive features three programmable digital inputs, one configurable analog input, and one relay output contact. Commissioning a replacement unit is straightforward through Lenze's removable Electronic Programmable Module (EPM) plug-in memory chip. Parameters can be duplicated offline using the Lenze EPM Programmer EEPM1RA or managed via Lenze Global Drive Control (GDC) software. Transferring the original EPM chip directly into a spare ESMD222X2TXA allows full parameter migration without requiring software tooling, while technical support from ABC Industrial Parts can assist when preparing spare drives or recovering parameter settings.
The drive provides real-time status indication and diagnostic feedback via its 3-digit LED display, showing active output frequency, motor current, DC bus voltage, or error codes. Operational issues such as overcurrent (OC1, OC2, OC3), DC bus overvoltage (OU, Ob), line undervoltage (LU), or heatsink overheating (OH) can be evaluated and resolved through routine checks on input power, motor cabling, cooling fans, and load conditions. Critical internal failures, such as internal drive failures (dF) or hardware faults (HF), indicate non-field-serviceable board-level issues. In these instances, sourcing a tested replacement or utilizing exchange options through ABC Industrial Parts offers a dependable path back to full production.

Programming and Configuration
The Lenze 00461758 ESMD222X2TXA frequency inverter utilizes an Electronic Programmable Module (EPM) as its core parameter storage mechanism. Drive settings, including V/f curve profile, switching frequency selection (4, 8, or 10 kHz), acceleration/deceleration times, and I/O mapping, are stored on this removable non-volatile chip. Moving the EPM chip from a failed drive directly to a spare unit transfers the full parameter set instantly without requiring a computer connection.
Offline configuration and chip duplication can be performed using the dedicated Lenze EPM Programmer EEPM1RA. This standalone tool enables maintenance teams to read, back up, or clone parameter profiles stored on EPM memory modules. Alternatively, full commissioning, live data monitoring, and parameter adjustments can be managed on a PC using Lenze Global Drive Control (GDC) software.
Communication and System Integration
The ESMD222X2TXA drive integrates into machine control circuits using physical control terminals comprising three programmable digital inputs, one configurable analog input, and one heavy-duty relay output. The digital inputs support functions such as Fast Stop activation or external fault monitoring, while the analog input accepts standard reference signals for motor speed adjustment.
Designed for 3-phase 400 V to 480 V AC industrial mains, the drive generates a controlled variable-frequency output up to 500 Hz with a continuous output current of 5.6 A at 400 V and 4.8 A at 480 V. It supports standard remote control option connections to interface with higher-level PLC networks or external keypads.
Diagnostics and Status Indication
Operational monitoring is provided by the integrated 3-digit LED keypad display on the front panel of the drive. During active operation, the display presents real-time motor status parameters, including output frequency, motor current, and internal DC bus voltage.
When a fault condition arises, the display flashes or lights solid to output specific fault codes. Diagnostics can also be accessed remotely through a PC running Lenze Global Drive Control (GDC) software to observe real-time drive operating conditions.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| 3-Digit LED Display | Red - Solid / Flashing | Displays operational status (e.g., current output frequency, output current), parameter numbers/values, or active error fault codes. |
Replacement and Spare Part Considerations
When swapping out an existing Lenze 00461758 ESMD222X2TXA drive, parameter consistency can be maintained by transferring the plug-in EPM chip from the original unit directly into the replacement inverter. This direct hardware transfer eliminates the need to manually re-enter parameters or perform software commissioning in the field.
Ensure that the replacement installation respects the IP20 rating and provides sufficient airflow to dissipate the unit's 90 W power loss. If upgrading or migrating away from legacy smd series hardware, the Lenze i510 and i550 series cabinet frequency inverters serve as the recommended modern successor line.
