Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVF8222-E is a 22 kW frequency inverter belonging to the 8200 vector series, engineered to deliver speed and torque regulation for 3-phase AC asynchronous motors in industrial automation systems. Operating across an input supply voltage range of 320 to 528 V AC at 45 to 65 Hz, this panel-mount drive delivers up to 47 A continuous output current and supports peak transient currents up to 70.5 A for 60 seconds. Motor control capabilities include programmable linear or quadratic V/f characteristics as well as dynamic open-loop sensorless vector control, supplying output frequencies from 0 to 480 Hz at a default 4 kHz switching frequency. Power dissipation during rated operation reaches 620 W, and built-in brake chopper terminals (+UG, -UG) allow direct connection of an external braking resistor to manage regenerative energy during fast deceleration cycles.
System connectivity relies on an integrated Function Module Interface (FIF) slot, which accepts plug-in fieldbus and expanded I/O modules to integrate the drive into broader machine controls. Commissioning a replacement unit requires transferring parameter profiles and matching fieldbus communication settings before operation. The drive contains four internal parameter sets stored within non-volatile EEPROM memory. Parameter configuration can be saved and loaded using the optional Lenze XT Keypad (E82ZBB001) or transferred via a computer connection running Lenze Global Drive Control (GDC) software. Technical guidance from ABC Industrial Parts can assist maintenance teams in verifying spare unit compatibility and preparing parameter configurations prior to installation.
Real-time operational monitoring is supported by two front-panel LED indicators: a green Ready/Operation LED indicating supply power and drive enable state, and a red Fault/TRIP LED indicating active warning or shutdown conditions. Diagnostics are expanded using the XT Keypad display to view active TRIP codes and status flags (IMP, STP, OK, TRIP) or by reviewing GDC software parameters C0183 and fault log memory C0161. Onboard non-volatile fault memory logs the last four TRIP conditions in parameters C0161 through C0164. When persistent internal faults or memory corruptions arise that cannot be cleared through field adjustments, a tested exchange unit or professional repair through ABC Industrial Parts provides a rapid path to restoring machine operation.

Programming and Configuration
Drive configuration for the Lenze EVF8222-E frequency inverter is managed via the optional Lenze XT Keypad (E82ZBB001) or through Lenze Global Drive Control (GDC) software connected via a PC adapter interface. The basic inverter architecture incorporates four complete onboard parameter sets maintained within internal non-volatile EEPROM memory, allowing flexible drive adaptation across varying plant operating conditions.
During commissioning or replacement, essential parameters including motor rated current (C0087), acceleration ramp time (C0012), V/f boost settings, and carrier switching frequency must be calibrated to match the connected motor and mechanical load. When utilizing the XT Keypad, active parameter sets can be uploaded from an existing drive and transferred to a replacement unit. Alternatively, GDC software enables offline file creation, back-up parameter set archiving, and direct upload/download operations.
Communication and System Integration
System integration is achieved through the modular Function Module Interface (FIF) slot located on the front of the basic unit. This interface slot accommodates plug-in communication options, including the Lenze Standard I/O module (E82ZAFSC), Application I/O module (E82ZAFAC), PROFIBUS-DP module (E82ZAFPC), and CANopen module (E82ZAFCC), as well as DeviceNet, INTERBUS, and LECOM serial communication interfaces.
For fieldbus network integration, network communication status is monitored via parameter C0150. Integration into CAN system bus topologies requires precise verification of node addresses, transmission baud rates, and system bus line termination using 120-ohm resistors to eliminate communication timeouts (code CE0) or internal module interface disruption (code CE1).
Diagnostics and Status Indication
The Lenze EVF8222-E inverter incorporates localized LED indicators, keypad display status flags, and software monitoring tools for real-time status indication. Two front-mounted LEDs provide instant visual feedback regarding operational readiness and fault conditions.
Detailed status monitoring is accessible using the optional XT Keypad LCD, which displays active TRIP codes alongside operational flags including IMP (pulses inhibited), STP (stop active), OK (drive ready), and TRIP (fault condition). In software-driven diagnostics, Lenze Global Drive Control (GDC) evaluates real-time operating parameters such as parameter C0183, while internal EEPROM fault memory logs the four most recent TRIP fault codes in parameters C0161 through C0164.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Fault / TRIP | Red - Illuminated or Flashing | Active TRIP fault or warning condition present |
| Ready / Operation | Green - Illuminated or Flashing | Power supplied and inverter ready; flashing indicates normal enabled operation |
Replacement and Spare Part Considerations
When replacing an existing unit with a spare Lenze EVF8222-E frequency inverter, verifying voltage ratings (320-528 V AC) and current capacity (47 A) is required to ensure physical and electrical drop-in compatibility. Before placing a spare unit into operation, the original FIF expansion module (such as PROFIBUS E82ZAFPC or CANopen E82ZAFCC) must be uninstalled from the failed drive and securely seated into the FIF slot of the replacement basic unit.
A replacement drive does not function as a direct plug-and-run module without proper parameter configuration. Active parameter profiles must be downloaded to the spare inverter using either an XT Keypad or Lenze Global Drive Control software. When internal electronic faults prevent standard parameter transfers, specialized component-level data recovery from internal EEPROM memory can assist in extracting stored parameter sets from defective units.

Frequently Asked Questions
What tools are required to configure parameters on the Lenze EVF8222-E inverter?
Parameter configuration requires either an optional Lenze XT Keypad (E82ZBB001) attached directly to the unit or a PC running Lenze Global Drive Control (GDC) software connected via an adapter interface.
Can a replacement EVF8222-E drive run without parameter programming?
No, a replacement unit must be loaded with the parameter settings from the original drive—including motor current parameters, acceleration ramps, and fieldbus profiles—before it can operate in a machine.
How are fieldbus modules attached to the EVF8222-E drive?
Fieldbus adapters, such as PROFIBUS-DP (E82ZAFPC) or CANopen (E82ZAFCC), plug directly into the Function Module Interface (FIF) expansion slot located on the front panel of the drive.
What do the front-panel status LEDs indicate on the EVF8222-E?
The green Ready/Operation LED indicates incoming mains power and inverter readiness (flashing when operational), while the red Fault/TRIP LED illuminates or flashes when an active fault or warning trip is present.
How does the inverter store parameter sets and fault history?
The drive stores up to four parameter profiles in non-volatile onboard EEPROM memory, while parameters C0161 through C0164 store a history of the last four TRIP fault codes.
What should be done if an H05 fault code is displayed?
An H05 code indicates an internal hardware failure in the power board, gate drive, or microcontroller. Power to the unit should be cycled; if the error persists, the fault is internal and non-field-serviceable, requiring drive repair or replacement.
