Product Information
The Lenze 00382653 EVD4906-E is a digital AC servo drive controller from the Lenze 4900 Series designed for precise positioning, speed, and torque control in industrial automation. Operating on a nominal 3-phase mains supply of 400 V AC to 480 V AC across an allowable input range of 323 V AC to 528 V AC, this compact drive unit delivers a continuous output current of 6 A and a 5-second peak overload rating of 12 A. Integrated single-axis positioning logic enables point-to-point positioning routines, programmed profiles, and multi-axis synchronized motion without requiring external PLC positioning hardware. An independent 24 V DC control board logic input maintains controller processing, parameter memory, and fieldbus communication during main power interruptions.
Connecting and commissioning a replacement EVD4906-E requires matching the existing fieldbus options and transferring the application parameter set. The drive incorporates a 9-pin Sub-D connector X7 for resolver motor feedback, six programmable digital inputs, four digital outputs, two differential analog inputs, and two analog outputs. An onboard high-speed CAN/CANopen system bus interface enables direct inter-drive synchronization, while optional fieldbus modules such as PROFIBUS-DP (2131/2133), INTERBUS (2111/2112), or LECOM can be installed via expansion sockets. A replacement drive cannot run on factory defaults; parameter files must be loaded using Lenze Global Drive Control (GDC) software version 4.x or higher, or copied from a donor module using a plug-in Operating Module Keypad 2102 or 8201BB into non-volatile EEPROM storage. Engineering support from ABC Industrial Parts can assist with parameter backing up and device verification during replacement.
Diagnostic conditions are monitored via front-panel status LEDs, plug-in keypads, or connected engineering software. A green LED indicates ready and normal operating status, while a red fault LED signals an active drive TRIP condition. Diagnostic parameters C0168 (TRIP history) and C0183 (drive status) assist technicians in identifying faults such as OC1 (overcurrent), OC5 (ground fault), OU (DC bus overvoltage), LU (DC bus undervoltage), or P12 (resolver feedback error). If internal hardware errors like EE (EEPROM memory error) or H05 (internal hardware defect) persist after cycling power and re-downloading parameters, or if overcurrent fault OC1 occurs with the motor leads disconnected, internal power board failure has occurred. In such cases, replacing the faulty unit with a tested exchange spare from ABC Industrial Parts provides a fast path back to operational capability.

Programming and Configuration
Parameterization and commissioning for the Lenze EVD4906-E servo drive controller are managed using Lenze Global Drive Control (GDC) software version 4.x or higher, or directly through plug-in operating modules such as Keypad 2102 or 8201BB. Non-volatile EEPROM memory within the controller stores all motion profiles, positioning data, PID tuning parameters, and terminal configurations, retaining them securely during full power dropouts.
When installing a spare drive, parameter sets can be cloned directly from a functional unit using the keypad copy function or downloaded from a saved GDC project file over the communication interface. If memory corruption occurs or factory settings are needed, setting parameter C0002 to 1 clears custom data and restores factory defaults, allowing a clean parameter file to be reloaded into memory.
Communication and System Integration
The Lenze EVD4906-E includes an onboard high-speed CAN/CANopen system bus interface capable of operating at communication rates up to 500 kbit/s. This bus permits direct, real-time data exchange between multiple servo drives for multi-axis velocity and position synchronization. To maintain signal integrity across the CAN network, physical end nodes require 120-ohm terminating resistors.
For connection to broader plant control networks, the drive supports optional plug-in fieldbus modules. Options include PROFIBUS-DP using Lenze 2131 or 2133 communication modules, INTERBUS via 2111 or 2112 modules, and LECOM interfaces. Node addresses, baud rates, and station parameters are configured within the drive's parameter structure to establish communication with host controllers.
Diagnostics and Status Indication
Real-time diagnostic feedback on the EVD4906-E is provided through front-panel LED indicators, plug-in LCD or 7-segment keypads, and software diagnostic tools. The GDC software package includes a real-time diagnostic window and oscilloscope function to monitor velocity, torque, position error, and I/O status during operational cycles.
Active drive status and trip history are recorded in dedicated parameter registers. Parameter C0183 reflects live operating conditions, while parameter C0168 maintains a log of historic fault codes. Front panel LEDs give immediate feedback on operational readiness and drive trip faults.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Ready / Operating | Green - Solid / Flashing | Normal operating status or ready for operation |
| Fault / TRIP | Red - Solid / Flashing | Drive trip fault condition active |
Replacement and Spare Part Considerations
When replacing a Lenze EVD4906-E servo drive, confirm that the spare unit matches the required electrical ratings (6 A continuous output, 400/480 V AC power input) and contains any specific communication option cards required by the machine setup, such as PROFIBUS-DP (2131/2133) or INTERBUS (2111/2112) modules.
The 24 V DC control board logic supply feature allows maintenance teams to power up the control card independently of the 3-phase 400 V AC power grid. This enables safer parameter loading via Lenze GDC software or Keypad 2102 / 8201BB before applying high voltage to the motor power terminals.
Ensure that physical CAN bus termination resistors (120 ohms) are properly seated on the end nodes of the system bus network, and verify that resolver feedback cabling is connected securely to 9-pin Sub-D socket X7 prior to enabling the drive stage.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|

Frequently Asked Questions
What software is used to parameterize the Lenze EVD4906-E drive?
The Lenze EVD4906-E is programmed and parameterized using Lenze Global Drive Control (GDC) software version 4.x or higher, or directly using a handheld Keypad 2102 or 8201BB operating module.
Can I transfer parameters to a replacement EVD4906-E without a PC?
Yes. Using a plug-in Operating Module Keypad 2102 or 8201BB, parameters can be saved from the original drive and copied directly into the non-volatile EEPROM memory of the replacement controller.
What type of motor feedback does the EVD4906-E accept?
The drive features a dedicated resolver feedback interface connected through a 9-pin Sub-D connector labeled X7.
How is multi-axis synchronization configured on this model?
Multi-axis coordination is handled over the onboard CAN/CANopen system bus interface at speeds up to 500 kbit/s, requiring 120-ohm terminating resistors at both physical ends of the bus.
What does fault code OC1 indicate on the drive?
Fault code OC1 indicates an overcurrent or short-circuit condition. If OC1 continues to trip even after disconnecting the motor leads, an internal power board output stage defect is present and the drive requires service or replacement.
