EVS9326-ESV004 Lenze 9300 Series 3-Phase Servo Drive Controller

Product Overview

The Lenze EVS9326-ESV004 is a high-dynamic Series 9300 servo inverter engineered for precision multi-axis motion control and synchronized industrial automation. Operating from a 3-phase 400 to 480 V AC supply at 50/60 Hz, this drive delivers 11 kW (14.75 HP) of rated active power for demanding packaging, converting, and material-handling machinery. The EVS9326-ESV004 features an integrated safe standstill function that interrupts torque generation without disconnecting main power, accelerating machine restart cycles during operator interventions.

Housed in a panel-mount IP20 chassis, the controller includes an onboard LED diagnostic display for rapid parameter monitoring and fault identification. Engineers can select between 8 kHz and 16 kHz switching frequencies to balance high continuous current output against acoustic motor noise reduction.

Performance & Thermal Rating Matrix

Installation & Commissioning Protocol

• Cabinet Mounting: Secure the EVS9326-ESV004 vertically on a conductive, unpainted galvanized mounting plate to ensure optimal EMC grounding.
• Airflow Clearance: Maintain at least 100 mm of unobstructed vertical ventilation space above and below the heatsink fins to prevent thermal derating near 60°C.
• Motor Shielding: Terminate shielded motor power and resolver/encoder cables using 360-degree EMC clamps directly at the drive shield busbar.
• Safety Wiring: Wire the dual-channel Safe Standstill terminals to a certified safety relay or safety PLC before executing initial motor auto-tuning.

Frequently Asked Questions (FAQ)

Q1: Why does continuous output current drop from 23.5 A to 15.3 A when switching from 8 kHz to 16 kHz?

A1: Doubling the PWM switching frequency doubles IGBT switching losses inside the inverter stage. Reducing the continuous current limit to 15.3 A prevents power semiconductor junction overheating while delivering quieter motor operation.

Q2: How does the Safe Standstill function on the EVS9326-ESV004 differ from cutting main 480V contactor power?

A2: Safe Standstill blocks pulse-width modulation signals to the output IGBTs, removing motor torque safely while keeping the DC bus charged and fieldbus communications active. Operators can clear jams and resume production immediately without waiting for capacitor pre-charge cycles.

Q3: Can I transfer existing parameters from a failed Series 9300 controller onto a replacement EVS9326-ESV004?

A3: Yes, technicians can transfer the complete parameter set in seconds by swapping the pluggable keypad module (EMZ9371BC) or uploading the parameter file via Lenze Global Drive Control software over the LECOM interface.

Q4: What derating rules apply if control cabinet temperatures exceed 40°C up to the 60°C limit?

A4: Above 40°C ambient temperature, engineers must derate the rated output current by approximately 2.5% per degree Celsius to prevent over-temperature trips (OH) during sustained high-duty cycles.

Q5: Buying Guidance: How do I verify that the EVS9326-ESV004 matches my machine's mechanical frame and firmware?

A5: Confirm the exact suffix ESV004 on your existing nameplate to ensure identical hardware revision, Safe Standstill terminal pinout, and 11 kW power stage dimensions for drop-in cabinet replacement without rewiring.
