Lenze EVS9326-EI 9300-Series Servo Drive

Designed for high-performance motion control within coordinated multi-axis systems, the Lenze EVS9326-EI operates as a closed-loop servo inverter within the legacy 9300-Series family. This unit delivers precise speed, torque, and position control for demanding industrial automation architectures, providing a rated power output of 11.0 kW in a robust, cabinet-mounted form factor.

Key Features

• Integrated system bus (CAN) for seamless multi-drive synchronization.
• High overload capacity for dynamic acceleration and deceleration phases.
• IP20 protection rating designed for clean, dry control cabinet environments.
• Flexible feedback interface supporting resolvers and incremental encoders.
• Comprehensive diagnostics and parameterization via Global Drive Control (GDC) software.

Applications

• Packaging machinery and continuous material handling lines.
• Gantry robots, positioning axes, and pick-and-place systems.
• Rotary indexing tables and synchronized electronic gearboxes.
• Textile manufacturing and printing press tension control.

Alternative Models & Compatibility

The "EI" suffix designates this unit as the standard execution featuring incremental encoder input/output capabilities. It can directly replace older EVS9326-ES units in most applications, provided the parameter set is migrated and verified using Lenze Global Drive Control (GDC) software. Ensure that the firmware version of the replacement unit matches or exceeds the original to prevent fieldbus mapping mismatches.

Application Pitfalls & Engineering Notes

Because this drive is IP20 rated, it must be installed in a clean, dust-free control cabinet. At 11.0 kW continuous output, thermal dissipation is significant. Maintain a minimum vertical clearance of 100 mm above and below the unit to prevent localized overheating. For high-inertia applications, an external braking resistor must be connected to terminals UG+ and BR to prevent overvoltage trips (fault code OU) during rapid deceleration.

Commissioning & Wiring Tips

Always use double-shielded, twisted-pair cabling for the resolver (X3) and encoder (X4) feedback loops. Ground the cable shields at both ends using low-impedance EMC shield clamps to prevent high-frequency noise from corrupting the feedback signal. When integrating the drive into a CAN network via X6, ensure a 120-ohm terminating resistor is physically installed at both ends of the bus line.
