Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVF8203-E is a 1.5 kW frequency inverter belonging to the 8200 vector product family, engineered for precise AC motor speed control and dynamic torque regulation. Designed to operate on a single-phase or three-phase supply voltage between 180 V AC and 264 V AC, this compact drive delivers a rated output voltage of 230 V AC with a continuous output current of 7 A and an input current rating of 13.5 A. Featuring flexible V/f characteristic control and sensorless vector control, the inverter achieves optimal motor performance across an adjustable output frequency range up to 480 Hz at an 8 kHz switching frequency, making it suitable for material handling conveyors, HVAC fans, and centrifugal pumps in IP20 environments.
Connecting and commissioning the EVF8203-E into an existing control system relies on its integrated control terminals, which feature 4 programmable digital inputs, 2 digital outputs, 1 programmable relay output, and 1 analog setpoint input supporting 0-10V, 0-20mA, or 4-20mA signals. An option slot accommodates fieldbus modules such as CANopen (EMF2175IB or EMZ8221WW), PROFIBUS-DP (EMF2133IB), INTERBUS, or LECOM RS-232/RS-485 interfaces. Installing a spare drive is not a simple plug-and-play swap; the new unit requires transfer of operational parameters from internal non-volatile EEPROM memory, which holds up to four switchable parameter sets. Parameter cloning and configuration restoration can be completed using the pluggable Keypad XT (EMZ8201BB) or PC-based software tools including Lenze Global Drive Control (GDC) and EASY Starter, where ABC Industrial Parts can assist in parameter extraction and drive preparation.
Diagnostic feedback on the EVF8203-E is displayed directly through status LEDs, featuring a red Trip/Fault indicator for active faults and a green Ready/Operation indicator for active power stage status. Detailed troubleshooting is supported via fault code readouts on the optional Keypad XT display, live software monitoring via GDC, and internal diagnostic parameters C0161 for the active fault and C0168 for fault history logs. When encountering supply dips or line anomalies, basic checks should confirm incoming line voltage across the 180–264 V AC range, fieldbus cabling, and terminal wiring. Internal electronic failures or corrupted memory conditions, indicated by internal hardware error codes such as H05 or system memory errors like E01, cannot be serviced in the field and require replacing the drive or utilizing expert repair services from ABC Industrial Parts.

Programming and Configuration
Programming and parameterization of the Lenze EVF8203-E frequency inverter are managed through software engineering tools or direct interface keypad hardware. The drive supports up to four complete, independently switchable parameter sets stored directly within internal non-volatile EEPROM memory. These multiple parameter sets allow complex machinery to adjust operating profiles dynamically without requiring external software reloads during standard operation.
PC-based setup and parameter transfer are executed using Lenze Global Drive Control (GDC) or EASY Starter software connected via supported communication hardware. For fast field commissioning without a PC, the optional pluggable Keypad XT (EMZ8201BB) connects directly to the drive interface. The Keypad XT allows technicians to modify parameters, upload complete configuration profiles, and clone settings seamlessly from a source drive to a replacement unit, reducing line downtime during drive swaps.
Communication and System Integration
The EVF8203-E integrates into modern control architectures via flexible onboard terminal interfaces and pluggable communication option slots. Standard control wiring includes 4 programmable digital inputs, 2 digital outputs (including a relay output), and 1 analog input. The analog channel accepts standard setpoint signals including 0-10V voltage inputs as well as 0-20mA and 4-20mA current loops, allowing direct speed reference control from analog sensors or system controllers.
Higher-level fieldbus automation is enabled by inserting dedicated interface modules into the drive's integrated option slot. Supported fieldbus options include CANopen modules (EMF2175IB and EMZ8221WW) and PROFIBUS-DP modules (EMF2133IB), alongside INTERBUS and LECOM RS-232/RS-485 serial communication modules. When fieldbus integration is configured, loss of process data triggers specific diagnostic monitoring codes, ensuring rapid response to network dropouts across the bus architecture.
Diagnostics and Status Indication
The Lenze EVF8203-E features clear diagnostic indications designed for fast status assessment and fault tracing. Front panel LED indicators provide instant visual feedback on operational readiness and drive trips. Advanced diagnostics are accessed electronically through parameters C0161, which displays the active fault, and C0168, which logs historic fault events for post-failure analysis.
Detailed fault code messages are rendered on the Keypad XT display (EMZ8201BB) or transmitted in real time over software interfaces like Lenze Global Drive Control (GDC) or EASY Starter. Additionally, digital and relay outputs can be assigned to signaling functions to trip external alarms or notify an upstream PLC during fault conditions.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Trip / Fault Indicator | Red - Solid / Flashing | Indicates active drive fault or trip condition |
| Ready / Operation Indicator | Green - Solid | Inverter power stage is ready or active in normal operation |
Replacement and Spare Part Considerations
Replacing an operational Lenze EVF8203-E requires careful attention to drive parameters and system option modules. Because the 8200 vector series is discontinued by the manufacturer, identifying exact replacement units or evaluating migration paths is critical for maintaining equipment availability. When installing a replacement EVF8203-E, any optional communication module (such as PROFIBUS-DP EMF2133IB or CANopen EMF2175IB) must be moved from the original unit to the replacement inverter slot.
Before putting a spare inverter into service, the existing motor control parameters, switching frequency settings, and digital I/O configurations must be transferred. This is accomplished either by cloning the settings via the Keypad XT (EMZ8201BB) or by restoring a software backup using Global Drive Control (GDC). If migrating to current generation hardware, Lenze recommends the i510 Cabinet series, specifically model i51AE215F10010000S, which requires system reconfiguration and parameter translation.
