Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVF8226-E is a panel-mounted 8200 Series frequency inverter engineered for precise 3-phase AC motor speed control in industrial automation applications. Delivering a rated power output of 15 kW (20 HP), this drive operates across a 3-phase mains voltage range of 320 V AC to 528 V AC, producing continuous output currents of 32 A at 400 V AC and 27 A at 480 V AC. It utilizes V/f characteristic control with adjustable linear and quadratic curve profiles to manage motor output frequencies from 0 to 480 Hz with a default 4 kHz switching frequency that can be adjusted up to 16 kHz. Designed with a robust panel-mount form factor, the drive supports variable speed control for centrifugal pumps, industrial fans, conveyors, and general machine tool drives.
Connecting the EVF8226-E into an existing control system involves utilizing its built-in I/O terminals, which comprise six programmable digital inputs, one digital output, two analog inputs (0-10V or 0-20mA), one analog output, and an integrated status relay contact rated for up to 250 V AC. An integrated automation slot accepts plug-in fieldbus modules such as the EMF2133IB PROFIBUS card, EMF2171IB CANopen system bus card, INTERBUS, or LECOM RS232/RS485 interface. Replacing a failed drive requires transferring the operational configuration, which can be accomplished using the optional EMZ8201BB keypad module or Lenze Global Drive Control (GDC) software V4.0 or higher. Because the unit maintains dual non-volatile parameter sets stored in internal EEPROM memory, technicians can restore parameter backups or clone parameters directly. When internal memory cannot be read normally, ABC Industrial Parts can assist with parameter extraction from damaged control boards to simplify swap-outs.
Operational status and fault conditions are signaled directly via front-panel LEDs, including a solid green LED for normal operation and a solid red LED for fault trips. Detailed diagnostic readouts and historical fault ring buffers can be accessed through an attached EMZ8201BB keypad or GDC software. Trip codes highlight specific conditions such as overcurrent during acceleration (OC1), deceleration (OC2), or constant speed (OC5), DC link overvoltage (OU), DC link undervoltage (LU), heatsink overtemperature (OH), mains phase failure (LP), and memory corruption (EEr). First-line troubleshooting should include verifying line power balance, checking motor wiring insulation with a megohmmeter, and inspecting heatsink cooling fans. If persistent hardware faults such as H05 occur or overcurrent trips persist with the motor disconnected, internal power section damage is present, and exchanging the unit with a tested spare from ABC Industrial Parts offers a fast path back to full production.

Programming and Configuration
Lenze Global Drive Control (GDC) software V4.0 or higher and the EMZ8201BB keypad module serve as the primary engineering tools for configuring and commissioning the EVF8226-E frequency inverter. Parameter navigation enables precise tuning of V/f characteristic curves, motor current protection limits, acceleration and deceleration time ramps, and carrier switching frequencies up to 16 kHz.
The drive features internal EEPROM non-volatile memory configured to hold two complete parameter sets. This feature allows technicians to switch between alternative operating profiles or clone configuration files between identical drives. A factory default reset can be executed directly by setting parameter C002 to 1 if parameter reinitialization is required prior to recalibration.
Communication and System Integration
Integrated fieldbus communication is enabled through a modular automation slot located on the front panel of the EVF8226-E. This interface accepts optional communication modules, including the EMF2133IB PROFIBUS module and EMF2171IB CANopen system bus module, as well as INTERBUS and LECOM RS232/RS485 options, permitting direct integration into centralized control networks.
For hardwired control systems, the inverter provides terminal wiring for 6 programmable digital inputs, 1 digital output, 2 analog inputs (0-10V or 0-20mA), and 1 analog output. An internal status relay with contacts rated up to 250 V AC provides dry-contact signal feedback for drive ready or fault conditions.
Diagnostics and Status Indication
The EVF8226-E provides front-panel diagnostic indications through two dedicated status LEDs. A green Operation LED signals normal drive activity and readiness, while a red Fault LED indicates an active drive trip condition. In-depth real-time parameters and a historical fault ring buffer can be accessed using an attached EMZ8201BB keypad or through Lenze Global Drive Control (GDC) software.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Operation | Green - Solid / Active | Normal inverter operation / ready status |
| Fault | Red - Solid / Active | Inverter fault / trip state |
Replacement and Spare Part Considerations
When replacing an EVF8226-E drive, verify that the replacement match has identical voltage (320-528V AC) and output current specifications (32 A at 400V / 27 A at 480V). Any optional communication modules, such as an EMF2133IB PROFIBUS or EMF2171IB CANopen card, must be unclipped from the defective drive and installed into the automation slot of the replacement unit.
Prior to running the application, parameter sets must be transferred to the replacement unit using either Lenze Global Drive Control (GDC) software V4.0+ or the EMZ8201BB keypad. It is recommended to perform a thorough motor insulation test and inspect line power fuses before re-energizing the system to prevent immediate component failure caused by external short circuits.
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 / Overcurrent during acceleration | Inverter output current exceeded peak current threshold during acceleration phase. | Acceleration time set too short; motor winding short circuit or ground fault; motor cable damaged; motor improperly sized. | Increase acceleration time (parameter C012); check motor wiring and motor winding insulation with megohmmeter. If error persists with motor disconnected, internal power module is defective — return unit for repair. |
| OC2 | Short circuit / Overcurrent during deceleration | Inverter output current exceeded peak threshold during deceleration phase. | Deceleration time set too short; excessive load inertia. | Increase deceleration time (parameter C013) or connect external braking resistor. |
| OC5 | Short circuit / Overcurrent at constant speed | Overcurrent detected during steady-state constant speed operation. | Sudden load impulse; mechanical blockage; earth fault; internal power transistor defect. | Check mechanical drive train for binding or overload; inspect motor insulation. If error occurs immediately without connected motor, internal power section damaged — return unit for repair. |
| OU | Overvoltage DC link | DC bus voltage exceeded upper limit threshold (approx. 770 V DC). | Generator operation from overrun load; deceleration time too fast; mains supply overvoltage spike. | Extend deceleration time or connect dynamic braking resistor module. |
| LU | Undervoltage DC link | DC bus voltage dropped below minimum operating limit. | Mains supply voltage too low; input power phase loss; main fuse blown. | Check supply voltage mains input and line fuses; verify phase continuity. |
| OH | Heatsink overtemperature | Drive heatsink temperature exceeded maximum allowable thermal limit. | Cooling fan clogged or failed; inadequate ventilation space; ambient temperature too high; persistent drive overload. | Clean heatsink cooling fins; verify fan operation; reduce ambient temperature or improve cabinet air circulation. |
| OH4 | Motor thermal overload (PTC) | Motor thermistor/PTC sensor triggered high temperature alarm. | Motor thermal overload; cooling fan on motor defective/clogged; PTC sensor wiring damaged or loose. | Allow motor to cool down; check motor loading; inspect motor fan and PTC thermistor wiring. |
