Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVF8204-E is a single-phase frequency inverter within the 8200 vector drive family, engineered for variable speed and torque regulation of standard three-phase AC motors up to 2.2 kW (3.0 HP). Operating on a 230 V AC supply line across a 180 to 264 V AC voltage window, this drive delivers a continuous output current of 9.5 A with a 150% overload capacity reaching 14.25 A for up to 60 seconds to handle high-inertia startup requirements. It supports sensorless vector control alongside linear and quadratic V/f characteristic curves, utilizing a standard switching frequency of 8 kHz that can be adjusted between 2 kHz and 16 kHz for low-noise operation. Housed in a compact IP20 enclosure, the unit is constructed for panel mounting inside control cabinets across packaging machinery, material handling systems, textile manufacturing, and HVAC ventilation installations.
Control interfacing is established via integrated screw terminal blocks providing four digital inputs, one digital relay output, one configurable analog input, and one analog output. To integrate with higher-level plant automation networks, the drive includes a function module slot supporting snap-in communication adapters for LECOM (RS232/RS485), PROFIBUS-DP, CANopen, DeviceNet, or INTERBUS. Putting a spare EVF8204-E into service requires transferring the parameter dataset from the replaced unit. Configuration data can be copied directly through the optional EMZ8201BB operating keypad using its copy and paste function, or loaded from a backup file using Lenze Global Drive Control (GDC) software via the EMF2102IB PC interface adapter. Maintenance personnel can rely on ABC Industrial Parts to supply tested replacement hardware or assist in retrieving drive parameters during unexpected downtime.
Real-time drive status is indicated by front panel status LEDs: a green LED displays operational states such as controller inhibit or active drive output, while a red LED signals active warnings, controller lock, or TRIP faults. For detailed diagnostic checks, the EMZ8201BB keypad displays active fault codes, while parameter C0161 stores the historical error memory buffer for review via GDC software. Initial field troubleshooting should verify mains input line voltages, control wiring, braking resistor settings, and motor winding insulation resistance. Internal electronic component faults, micro-controller check errors, or EEPROM memory corruption cannot be serviced on site; in these instances, sourcing a tested exchange drive through ABC Industrial Parts provides a fast path to restoring production.

Programming and Configuration
Configuration of the Lenze EVF8204-E frequency inverter is executed either through the pluggable EMZ8201BB operating keypad module or via Lenze Global Drive Control (GDC) software running on a PC connected through the EMF2102IB interface adapter. The EMZ8201BB keypad plugs directly into the drive's front port, allowing technicians to inspect operational parameters, adjust control limits, and view fault history without requiring external computer hardware. The keypad includes a parameter memory feature that allows complete dataset backup from an active inverter and direct transfer into a replacement unit.
When utilizing Global Drive Control software, users can save complete parameter profiles, monitor drive variable values in real time, and analyze drive performance using built-in software oscilloscope functions. In scenarios where a parameter dataset becomes inconsistent or invalid parameter values trigger error code Pr, the drive can be returned to baseline conditions by setting parameter C0002 to 1, initiating a factory parameter reset before loading a known valid machine parameter profile.
Communication and System Integration
The EVF8204-E incorporates a dedicated function module slot on its front interface to facilitate fieldbus network integration. By attaching plug-in communication modules, the drive can interface with LECOM (RS232/RS485), PROFIBUS-DP, CANopen, DeviceNet, or INTERBUS automation networks. This modular system structure allows the drive to integrate into diverse PLC control architectures without changing the core inverter hardware.
For direct panel control and signal wiring, the inverter features integrated screw terminal connections. The I/O terminal strip supports four digital inputs for run commands and external trips, one digital relay output for operating status signals, one configurable analog input for frequency setpoints, and one analog output providing feedback parameters such as motor speed or output frequency.
Diagnostics and Status Indication
Front panel LED indicators provide instant operational feedback for basic troubleshooting. The green LED indicates drive status, flashing when the controller is in controller inhibit or ready state and glowing solid green when the inverter is enabled and driving the motor. The red LED acts as the primary alarm indicator, flashing during active warnings or sub-error conditions and remaining solid when the drive encounters a persistent TRIP fault or controller lock.
Detailed fault diagnostics are retrieved via the optional EMZ8201BB keypad display, which outputs diagnostic fault codes. The drive records historic trip occurrences in the internal fault buffer parameter C0161, which can be interrogated through the keypad interface or via GDC PC software.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Red LED | Red - Flashing / Solid | Flashing indicates active warning or sub-error; solid light indicates persistent fault condition / controller lock / TRIP status. |
| Green LED | Green - Flashing / Solid | Flashing indicates controller inhibit / ready state; solid light indicates inverter enabled and active drive operation. |
Replacement and Spare Part Considerations
When installing a replacement Lenze EVF8204-E drive, verify that the replacement unit shares the single-phase 230 V AC voltage rating and 2.2 kW power specification. Before applying power, remove the fieldbus communication card from the old unit and seat it firmly into the replacement inverter's function module slot to maintain network architecture compatibility.
A replacement drive will not operate correctly out of the box on default settings. All application-specific parameters—such as motor current limits, acceleration ramps, I/O terminal functions, and fieldbus communication addresses—must be transferred from the original drive. Parameter transfer is executed using the EMZ8201BB keypad copy/paste function or via Global Drive Control (GDC) PC software. For long-term hardware planning, note that Lenze recommends migrating to the i510 or i550 Cabinet series for modern cabinet retrofit projects.
