Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00399420, model EVD4906-E, is a 7.5 kW frequency inverter drive controller within the Lenze EVD4900 Series designed for precise speed, torque, and positioning control of three-phase AC motors. Operating across a mains voltage input range from 320 V AC to 550 V AC, this unit delivers a rated continuous output current of 16.5 A at 400 V AC with an output frequency range up to 480 Hz. Housed in an IP20 rated enclosure intended for vertical panel mounting inside electrical control cabinets, the drive provides dynamic motor regulation across automated packaging machinery, material handling conveyors, and industrial processing equipment.
For communication and motion synchronization, the EVD4906-E comes equipped with an integrated onboard CAN system bus interface alongside a modular expansion slot supporting option modules such as LECOM 2102IB/2111IB for RS-232, RS-485, or fiber-optic links, or PROFIBUS-DP module 2131IB. Placing a spare unit into service requires transferring device parameters, as drive settings stored in internal EEPROM memory must align with the target machine's operational requirements. Parameter backup and restoration can be completed using Lenze Global Drive Control (GDC) PC software or a pluggable 4900 series operating keypad. Maintenance teams often turn to ABC Industrial Parts for pre-tested spare drives and parameter transfer assistance to minimize production downtime.
Diagnostic monitoring is provided directly on the front panel through status LEDs: a solid Green LED indicates power stage operational readiness, while a Red LED signals an active TRIP fault condition. Detailed status reporting and historical fault logging are accessible through GDC software or keypad parameters C008 (TRIP fault memory) and C018 (actual status), as well as via a digital TRIP status relay output. When fault conditions such as an OC1 overcurrent fault or H05 internal hardware error persist after verifying motor insulation and external wiring, internal power stage or control board damage is indicated. In cases where field servicing is not possible, sourcing a tested replacement module through ABC Industrial Parts ensures a quick return to full operation.

Programming and Configuration
Configuring the Lenze 00399420 EVD4906-E drive controller relies on Lenze Global Drive Control (GDC) software or a pluggable 4900 series operating keypad. Through the GDC PC interface, commissioning engineers can adjust parameter settings, create drive backups, and observe real-time operational variables. Adjusted parameter values are saved directly into the onboard EEPROM storage, preserving configuration settings when control power is cycled.
Specific keypad code parameters facilitate system setup, parameter transfer, and system resets. Parameter C002 resets the inverter to factory default values, while parameter C003 executes a manual parameter write to the EEPROM. Diagnostic code C018 provides continuous display of live operating status, and parameter C008 records the TRIP fault log to aid in systematic system troubleshooting.
Communication and System Integration
The EVD4906-E model variant features an integrated onboard CAN system bus interface designed for high-speed multi-axis motion synchronization. Operating without requiring extra communication modules, this built-in bus enables peer-to-peer inter-drive synchronization across multi-axis automated packaging machinery and conveyor systems.
For higher-level network integration, the drive controller includes an expansion slot accommodating various plug-in communication modules. Supported options include Lenze LECOM modules 2102IB and 2111IB for RS-232, RS-485, or fiber-optic connections, as well as the PROFIBUS-DP module 2131IB. Integrating these modules requires setting node addresses, confirming proper bus termination resistors, and ensuring correct cable shield grounding.
Diagnostics and Status Indication
Real-time diagnostic feedback on the Lenze EVD4906-E is provided by onboard front status LEDs, a digital TRIP relay output, and internal parameter monitoring tools. A solid Green LED indicates that the drive power stage is active and ready for operation, whereas a Red LED illuminates or flashes during an active TRIP fault condition. The TRIP relay output triggers immediately upon a drive fault to alert master control systems.
Comprehensive diagnostic routines can be conducted using Lenze GDC software or the operating keypad. Keypad parameter C008 stores historical TRIP fault events for review, while parameter C018 provides real-time status code readouts to help identify issues ranging from mains undervoltage to communication timeouts.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Red LED (TRIP / Error) | Red - Illuminated or Flashing | Drive fault condition or active TRIP |
| Green LED (Ready / Operation) | Green - Solid | Normal drive ready state / power stage active |
Replacement and Spare Part Considerations
When replacing an existing drive, verify that the replacement part number matches 00399420 and carries the exact EVD4906-E model designation. The '-E' suffix identifies the inclusion of the onboard CAN system bus interface, which is required for applications utilizing inter-drive synchronization across multi-axis production equipment.
A replacement EVD4906-E drive is not pre-configured out of the box and requires parameter transfer before operating the machine. Parameter profiles stored on the original unit must be backed up using Lenze GDC software or an operating keypad, written to the replacement unit, and permanently stored to EEPROM using keypad code C003. Any installed LECOM or PROFIBUS-DP expansion modules must be transferred to the spare unit, and node address settings and fieldbus termination must be verified prior to applying line power.
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 / Earth fault | Instantaneous overcurrent during power-up or operation due to motor short circuit or earth fault. | Short circuit in motor cable, motor winding fault, earth fault, or internal inverter power stage defect. | Check motor and wiring for short circuits and insulation faults. If motor and cable are intact, internal hardware failure requires repair or unit replacement. |
