Lenze 8200 Vector Replacement Guide

Overview

The Lenze 8200 Vector frequency inverter series served as a cornerstone of industrial process automation for more than two decades, managing speed and torque in applications ranging from conveyor networks to high-speed packaging machinery. Following its end-of-life (EOL) declarations, maintaining production lines with legacy E82EV drives has become highly inefficient. Stocking obsolete spare parts introduces significant financial risks, and relying on used components reduces overall system reliability.

Migrating to the contemporary Lenze i550 frequency inverter series provides a direct remediation path. This technical guide outlines the conversion process, addressing mechanical mounting mismatches, power terminal re-wiring, control circuit re-routing, interface communication updates, and software Parameter translation.

Legacy Product Information

The Lenze 8200 Vector (primarily carrying part numbers beginning with E82EV) featured a modular construction model. Users combined a basic power module with a pluggable function module (FIF module) to meet specific application requirements. Power capacities spanned from 0.25 kW up to 90 kW with voltage options of 230V single-phase, 230V three-phase, and 400V/480V three-phase.

Key configurations of the legacy 8200 Vector series included:

• Standard Enclosure Types: Axis modules with heatsinks, cold-plate variations, and thermaly isolated push-through designs.
• Standard Fieldbus Modules: Keypad XT (E82ZBC), LECOM-A/B (RS232/RS485), CANopen (E82ZAFXC), PROFIBUS DP (E82ZAFPD), and Interbus (E82ZAFIB).
• Control Modes: V/f characteristic (linear or quadratic), sensorless vector control, and closed-loop feedback variants.

Finding direct replacement boards or matching components for these older units is no longer feasible, making a full controller upgrade the only reliable solution.

Recommended Replacements

The modern Lenze i550 series forms the recommended replacement path for the 8200 Vector. When selecting your replacement hardware, make sure to choose the i550 series rather than the basic i510. While the i510 is suitable for standard V/f conveyor drives, only the i550 supports sensorless vector control, hoisting cycles, encoder feedback modules, and advanced fieldbus communications.

Use the technical mapping table below to cross-reference common legacy 8200 Vector drives with their modern i550 equivalents:

Note on part structures: Standard replacements are delivered with integrated EMI/RFI filters and safe-torque-off (STO) functions baseline, marked by the suffix matching the safety-specific standard codes.

Compatibility Considerations

1. Dimensional Footprints and Cabinet Real Estate

The i550 inverter models use a modern, narrow design (often referred to as 'bookstyle' format). This shape allows them to fit into tight cabinet configurations. However, output mechanical mounting hole patterns do not directly align with legacy units.

• 8200 Vector Size (e.g., E82EV152_4B): Width ~ 97 mm, Height ~ 240 mm, Depth ~ 140 mm.
• Equivalent i550 Model (e.g., i550-C1.5/400-3): Width ~ 60 mm, Height ~ 155 mm, Depth ~ 130 mm.

Because the new units are smaller, you will have plenty of cabinet space, but installing them will require drilling new mounting holes or using Lenze-designed DIN rail adapters and retrofitting plates.

2. Control Terminal Terminations

The wire terminals on the 8200 Vector cannot be plugged directly into the i550. The terminal identification scheme must be mapped manually to ensure correct IO tracking:

• Enable/Start Terminal: 8200 Vector Terminal 28 matches the i550 Digital Input DI1 (configured as controller enable/start).
• Basic Digital Inputs: Terminals E1 through E4 on the 8200 block translate to DI1 through DI4 on the i550 control block.
• Analog Outputs: Terminal 62/63 (0-10V analog speed output) maps directly to terminal AO1 and reference ground GND on the new drive.
• Relay Outputs: The fault signal relay terminals K11, K12, and K14 correspond to the i550's digital relay output contacts DO1A and DO1B.

3. Industrial Communications

If the legacy module used fieldbus communication (such as the E82ZAFPD PROFIBUS board), you will need to choose the matching interface option for the i550 chassis when ordering.

We recommend migrating away from outdated serial fieldbuses like PROFIBUS DP and CANopen. Instead, transition your PLC architecture to industrial Ethernet protocols like PROFINET, EtherCAT, or EtherNet/IP. The i550 series supports these modern protocols via built-in networks or dedicated communications modules.

Upgrade Benefits

Transitioning to the i550 series brings several technical performance upgrades:

• Fast Configuration Power-Off: By using the pluggable i500 USB diagnostic module, technicians can read, write, and duplicate complete parameter sets to the drive using computer software, even when the drive has no mains power.
• Energy Optimization: The i550 features energy-saving algorithms like VFC-eco mode, which reduces motor excitation losses under partial loads, bringing the system into alignment with modern IE2/IE3 motor control regulations.
• Integral Hardware Safety: The i550 contains functional safety circuitry built directly into the base drive architecture, achieving Safe Torque Off (STO) certified up to SIL 3 / PL e to replace external, hard-wired safety contactors.
• Refined Engineering Software: GDC (Global Drive Control) is replaced by the free Lenze EASY Starter tool, which provides online diagnostics, oscilloscope functions, and visual commissioning panels.

Common Migration Challenges

Parameter Vector Translation

There is no automated utility to export a parameter file (*.gdc) out of the legacy Global Drive Control workspace and import it directly into the modern EASY Starter platform. Configuration parameters must be manually translated. Maintain close track of critical target variables:

• Motor Nameplate Data: Ensure you map C00084 (Motor Rated Frequency) and C00087 (Motor Rated Current) to their modern counterparts under code block 0x2C01 (sub-indexes 1 to 6) in the i550 directory.
• V/f Base Custom Curves: If you are running tailored speed-torque ratios, you will need to manually re-plot those operational points in the i550's custom V/f multi-point parameter set under 0x2B12.

Closed-Loop Encoder Feedback

Legacy 8200 configurations required the E82ZAFAC module for HTL incremental encoder tracking. The i550 handles this differently; feedback requires a specialized control unit variant. Keep this in mind when specifying hardware, as standard i550 models do not feature encoder inputs out of the box.

Minimum Chopper Coil Resistance

Verify that any legacy dynamic braking resistors still in use match the minimum allowable braking resistance specified for the new i550 chopper circuit. Using a mismatched resistor with too low of a resistance can draw too much current and cause permanent damage to the new drive's internal brake transistor.

FAQ

Q: Can I use my old Keypad XT (E82ZBC) on the new i550 drive?

No, the mechanical connection ports and electrical interfaces are completely incompatible. You will need to use either the functional i550 Keypad (I5MADK0000000S) or the EASY Starter software running on a PC.

Q: How do I backup legacy configurations from the 8200 Vector before decommissioning?

Connect to the legacy drive using either a Keypad XT or a PC running Global Drive Control (GDC) via a LECOM diagnostic module (such as the EMF2102IB unit). Export the drive database parameters as a .gdc formatting file to use as a manual reference.

Q: Is the parameter code numbering system the same between the 8200 and the i550?

No. The 8200 Vector used three-digit codes (e.g., C0011 for acceleration time, C0012 for deceleration time). The i550 uses modern, structured, hex-indexed parameters (e.g., 0x2917 for Acceleration, 0x2918 for Deceleration) based on the CANopen and CiA 402 device profile standards.

Q: Can my legacy PLC control the new i550 drive via PROFIBUS?

Yes, you can order a version of the i550 that includes a dedicated PROFIBUS communications module (like the I55AE_P). However, we highly recommend upgrading your network infrastructure to PROFINET to ensure your system remains serviceable well into the future.

Q: Does the i550 mounting process require extra clearance for cooling air flow?

Yes. While the i550 can be mounted side-by-side without horizontal spacing, you must still maintain clearances of at least 50 mm at both the top and description bottom of the unit to ensure adequate air circulation around the heatsink.
