Physical Dimensions and Weight

• Dimensions (H×W×D): 680 × 440 × 285 mm (built-in/push-through design)
• Weight: 59.0 kg per official 9300 catalogue en 03/2009 (note: a mirror source lists 40.0 kg)
• Mounting style: Built-in/push-through installation for cabinet integration

Installation Guidelines

• Mount the unit vertically inside a cabinet that meets IP20 protection requirements.
• Keep generous clearance around the heatsink because this 55 kW unit dissipates 1470 W.
• Connect the 3/PE AC supply within the 320–528 V range and verify grounding.
• Wire the resolver or encoder to the Sub-D 9-pin connector before power-on.
• Apply output-current derating of 2.5 %/°C when ambient exceeds +40 °C.
• Configure CANopen node settings through the AIF interface or keypad.

Package Contents

• 1 × Lenze EVS9331-ER register controller servo inverter
• 1 × Sub-D 9-pin connector set for resolver and encoder ports

• 1 × Original packaging with protective inserts

Lifecycle and Migration Notes

• Lenze lists this model on its official "previous products" page as a legacy drive.
• Newer drive generations supersede the 9300 series in active production.
• Lenze confirms a migration path to the i950 drive platform.
• The i950 replicates 9300 servo behavior via a compatibility switch.
• Migration also uses the i950 PROFIBUS module and the L_ICIP library.
• No drop-in replacement shares the same order code.

FAQ

• Q: What is the rated power of the EVS9331-ER?
  A: It delivers 55.0 kW rated motor power for 4-pole asynchronous motors at 400 V.
• Q: How much output current does it provide?
  A: It provides 110.0 A nominal and 165.0 A maximum at 8 kHz switching frequency.
