Product Information
The Lenze I51AE215B10V10000S is a compact IP20 cabinet frequency inverter within the Lenze i500 product family. Designed for speed modulation of three-phase AC motors in control cabinet environments, this 1.5 kW (2.0 HP) drive operates on a single-phase 230V AC input supply (198 to 264V AC) and delivers a regulated 3-phase 0 to 230V AC output up to 7.0 A. It supports Sensorless Vector Control (SLVC) and V/f characteristic motor control methods across an output frequency range of 0 to 599 Hz. An integrated Class C2 EMC filter minimizes line-conducted interference inside the control enclosure.
Integrating this drive into a machine control architecture is straightforward thanks to built-in CANopen and Modbus RTU communication interfaces, alongside pluggable spring-clamp control terminals. To simplify commissioning and spare unit swaps, the inverter uses a pluggable EAM910000S EEPROM memory module. Parameter settings can be transferred instantly by moving the memory module from the original drive to the replacement without needing main supply power. Additional tools such as the Lenze EASY Starter engineering software via a USB adapter, an optional i500 keypad, or a WLAN module can be used for parameter adjustments and configuration management.
System status and operational readiness are indicated on the unit via RDY and ERR status LEDs. For advanced troubleshooting, the drive stores the last eight fault events in an internal buffer, accessible via EASY Starter or the Lenze Smart Keypad App. When power stage or internal hardware errors occur—such as phase-to-phase shorts or unrecoverable control board faults—the drive cannot be serviced in the field and should be returned for repair or replaced with a tested unit through ABC Industrial Parts.

Programming and Configuration
Parameterization of the Lenze I51AE215B10V10000S inverter is primarily handled using the Lenze EASY Starter commissioning software connected via an optional USB adapter module. The software provides access to motor parameter settings, such as configuring the motor rated current in parameter P303.01, adjusting acceleration and deceleration ramps, and selecting between V/f characteristic curves and Sensorless Vector Control (SLVC).
To eliminate the need for software re-programming during physical drive replacement, the inverter incorporates a pluggable EAM910000S parameter memory chip. All device parameters are saved to this EEPROM module, allowing offline transfer of complete parameter sets between hardware units without needing control voltage or main supply power. Alternatively, configuration changes can be performed directly at the cabinet using the plug-in Lenze i500 keypad (I5MADK0000000S) or wirelessly using the Smart Keypad App over an optional WLAN extension module.
Communication and System Integration
The I51AE215B10V10000S features built-in CANopen and Modbus RTU fieldbus interfaces directly on the control unit, eliminating the need for separate option cards for standard serial network connectivity. These protocols enable direct integration into industrial fieldbus networks for remote start/stop control, frequency setpoint modulation, and real-time operational monitoring.
For hardwired control signals, the drive is equipped with five digital inputs, one digital output, one relay output, one analog input, and one analog output. Wiring connections are completed using pluggable spring-clamp terminals that streamline cabinet assembly and accelerate swap-out procedures during routine maintenance.
Diagnostics and Status Indication
Operational status on the I51AE215B10V10000S is visible via two control panel LEDs labeled RDY (Ready) and ERR (Error). The green RDY LED illuminates solid or blinks to signal ready status and normal inverter operation, while the red ERR LED indicates an active error or fault state.
Detailed fault diagnostics are logged in an internal fault history buffer that records up to eight recent fault events along with operational state data. Diagnostic information can be monitored in real time or retrieved from the buffer using EASY Starter software via USB, or via the Lenze Smart Keypad App when equipped with an optional WLAN module.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| RDY | Green - Solid / Flashing | Ready status / Normal operation |
| ERR | Red - Solid / Flashing | Error status / Fault condition detected |
Replacement and Spare Part Considerations
When replacing a failed I51AE215B10V10000S unit, matching the exact part number ensures identical physical dimensions, 1.5 kW output rating, 230V single-phase input capability, and Class C2 EMC filter integration. Transferring the pluggable EAM910000S EEPROM memory module from the original drive to the replacement unit copies all parameters, motor settings, and fieldbus configurations without requiring software tools or main line power.
Before restoring power to a newly installed replacement drive, verify that the single-phase input wiring (terminals L1, N) and motor output wiring (terminals U, V, W) are secure and free of ground faults or inter-phase shorts. If the original memory module cannot be reused or is unreadable, ABC Industrial Parts can assist with parameter recovery from donor units or baseline configuration support.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| 0x2310 | Earth fault | Ground fault detected on inverter output terminals U, V, W. | Short circuit to motor earth frame, damaged motor cable insulation, or internal leakage current. | Check motor wiring and motor insulation using insulation tester. If wiring is intact, internal inverter power stage is damaged (return unit for repair). |
| 0x2320 | Short circuit | Excessive instantaneous current detected on power stage output. | Short circuit between motor phases, motor cable shorted, severe overload, or blown IGBT module. | Check motor phases for inter-phase short circuit. Check cable. If fault persists with motor disconnected, internal hardware fault (return unit for repair). |
| 0x3210 | DC-bus overvoltage | DC bus voltage exceeded upper limit. | Regenerative motor energy during deceleration, deceleration ramp time too short, or input mains voltage transient. | Increase deceleration time, activate DC bus voltage controller (Vdc-max controller), or fit braking resistor module if supported. |
| 0x3220 | DC-bus undervoltage | DC bus voltage fell below lower threshold. | Mains supply voltage drop, phase failure, or supply brownout. | Check input supply voltage across terminals L1 and N. Verify supply stability under load. |
| 0x3310 | Mains phase failure | Input AC line phase missing or severe line imbalance. | Blown supply fuse, loose power terminal connection, or mains voltage drop. | Check mains wiring, supply line fuses, and AC supply voltage at input terminals. |
| 0x4210 | Heatsink overtemperature | Power stage heatsink temperature exceeded maximum safety threshold. | Blocked cooling airflow, fan failure, ambient temperature too high, or drive overloaded. | Clean cooling fins, check internal fan operation, reduce ambient temperature or load current. |
| 0x6100 | Internal hardware failure | Internal control board or power section failure detected during self-test. | Hardware component malfunction, corrupt internal memory, board-level fault. | Cycle input power. If fault re-occurs, internal hardware failure — return drive for repair/replacement. |
| 0x7121 | Motor overload (I2t) | Motor thermal overload monitoring (I2t function) tripped. | Continuous operation above motor rated current, mechanical stall or overload on driven machine. | Check motor mechanical load, verify motor nameplate current settings in drive parameters (P303.01). |
