Product Information
The Lenze I51AE175F10010000S is a 0.75 kW (1.0 HP) frequency inverter belonging to the i510 series within the Lenze i500 product family. Designed as a compact drive module for control cabinet installation, it features an IP20 protection rating and operates across an input supply voltage range of 180 V AC to 264 V AC on either single-phase or three-phase 230 V AC power networks. The inverter delivers a rated output current of 4.0 A with an output voltage range of 0 to 230 V AC and output frequencies up to 599 Hz. Supporting linear V/f, square-law V/f, sensorless vector control (SLVC), and sensorless synchronous motor control (SLPSM), this unit provides precise motor speed regulation for induction and permanent magnet synchronous motors across conveyor systems, industrial pumps, fans, and packaging machinery.
Putting a replacement I51AE175F10010000S into service requires physical terminal connections and parameter synchronization with the machine controller. The drive features an integrated CANopen fieldbus interface alongside onboard I/O comprising 5 digital inputs, 1 digital output (50 mA), 1 relay output (250 V AC / 3 A), 1 multi-function analog input, and 1 analog output supporting 0-10 V, 0-20 mA, or 4-20 mA signals. Commissioning and setup are completed via the front Micro-USB port using Lenze EASY Starter software, or with optional modules including the i5MADK0000000S keypad, i5MADW0000000S WLAN module, or i5MADU0000000S USB module. Because a new spare unit does not contain plant-specific operating parameters, complete parameter restoration from a backup file or parameter extraction from a donor unit is necessary prior to motor operation, with technical support available through ABC Industrial Parts.
Drive operating status and fault conditions are monitored via three front panel status LEDs—RDY, CAN RUN, and CAN ERR—as well as status word registers and fault history logs accessible over fieldbus or diagnostic software. Active protection functions trigger specific error codes, including 0x2310 for overcurrent, 0x3210 for DC bus overvoltage, 0x3220 for DC bus undervoltage, 0x3130 for mains phase failure, and 0x8130 for CANopen bus off conditions. First-line field checks should verify supply voltage levels, motor insulation, output wiring connections, fieldbus baud rate configuration, and 120-ohm CAN termination resistors. Severe internal faults such as code 0x6100 reflect hardware board defects that are non-field-serviceable, where unit replacement or a tested exchange drive from ABC Industrial Parts represents the direct path back to full production.

Programming and Configuration
Programming and parameterizing the Lenze I51AE175F10010000S frequency inverter is carried out using Lenze EASY Starter engineering software connected via the built-in Micro-USB port on the front of the unit. The software interface allows service technicians to configure motor nameplate parameters, adjust acceleration and deceleration ramps, map digital and analog I/O functions, set up current limit thresholds, and define network parameters for CANopen communication.
Local configuration without a PC can be accomplished using direct plug-in operator modules. The i5MADK0000000S display keypad provides direct menu access for parameter editing, while the i5MADW0000000S WLAN module and i5MADU0000000S USB module provide wireless or direct physical connections for field transfer and saving of complete drive parameter files.
When commissioning a replacement drive or clearing parameter data error code 0x6300, a valid parameter file must be transferred to the inverter memory. If checksum errors occur, loading factory default settings and downloading the application parameter set via Lenze EASY Starter re-establishes correct operating parameters.
Communication and System Integration
The Lenze I51AE175F10010000S includes an integrated CANopen fieldbus interface that connects directly into automated control networks driven by standard CANopen master controllers. The interface supports real-time control, status word telemetry, and remote parameterization via the CANopen object dictionary without requiring additional fieldbus option cards.
Network operation is visually indicated by the CAN RUN and CAN ERR status LEDs located on the front panel. A solid green CAN RUN LED confirms Operational network state, flashing green indicates Pre-Operational state, and a single flash represents Stopped state. The CAN ERR LED flashes red during bus warning conditions and turns solid red when the interface enters a Bus Off state.
Integrating the inverter into a CANopen network requires establishing the matching node ID and baud rate settings. Reliable network communications depend on correct two-wire bus cabling with grounded shield lines and proper 120-ohm termination resistors installed at both physical ends of the CAN bus trunk to prevent code 0x8130 communication faults.
Diagnostics and Status Indication
Operational status and diagnostic evaluation for the I51AE175F10010000S are monitored through front-panel diagnostic LEDs, internal status word readouts over CANopen, and an integrated error log accessible via Lenze EASY Starter software or the optional i5MADK0000000S keypad module.
The primary RDY (Ready) status LED provides bi-color visual feedback on unit status: flashing green indicates the drive is ready or inhibited, solid green confirms active motor operation, flashing red indicates an active warning limit, and solid red alerts to an active trip fault. An unlit RDY LED indicates that supply power is disconnected or an internal hardware failure has occurred.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| RDY (Ready) | Green/Red - Solid / Flashing / Off | Green flashing = drive ready / inhibited; Green solid = drive active / running; Red flashing = warning; Red solid = fault active; Off = power off / internal hardware defect |
| CAN RUN | Green - Solid / Flashing / Single flash | Green flashing = Pre-Operational state; Green solid = Operational state; Single flash = Stopped state |
| CAN ERR | Red - Solid / Flashing / Off | Red flashing = Bus error / warning limit reached; Red solid = Bus Off state; Off = No CAN error |
Replacement and Spare Part Considerations
When replacing a defective drive with the Lenze I51AE175F10010000S, verify that the replacement unit matches the exact part number. This ensures identity with the 0.75 kW power rating, 4.0 A output current capacity, 230 V AC input rating, and integrated CANopen hardware build.
A replacement drive cannot run the application directly out of the box. Machine-specific parameters defining acceleration times, motor ratings, I/O functions, and CANopen node identifiers must be loaded onto the replacement unit using Lenze EASY Starter software, a WLAN or USB module, or the i5MADK0000000S keypad before starting the motor.
Prior to powering up a replacement inverter, conduct basic electrical checks: measure incoming line voltage (180 to 264 V AC), inspect output wiring on motor phases U, V, and W, check for short circuits to earth, and verify that 120-ohm fieldbus termination resistors are installed on the CANopen network.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
