Description

Product Introduction

Don’t let a blown drive kill your production line’s rhythm. The Lenze EVS9328-ESV100 is the workhorse of the 8200 motec series, specifically designed for decentralized applications where space is tight but performance can’t slide. It handles 0.75 kW loads with ease, commonly found in packaging machines, conveyors, and material handling systems across Europe and North America.This specific unit, the ESV100 variant, operates on a 240V single-phase input—making it perfect for retrofitting older machinery without needing a three-phase power supply. We source these as New Surplus to give you an alternative to the OEM’s often-staggering lead times. Honestly, for a component that usually costs less than $300, the downtime it prevents is worth ten times its weight in gold.

Application Scenarios & Pain Points

The “Humming” Conveyor StandstillImagine this: a bottling plant in Texas is gearing up for a holiday rush. Suddenly, the indexing conveyor feeding the capper stops. The motor is humming, but there’s no movement. The maintenance tech checks the HMI; the Lenze drive is showing a “PHF” (Phase Failure) fault. The input voltage checks out, but the internal DC bus is unstable. It turns out the intermediate circuit capacitors in the old EVS9328 have dried up.This is where the EVS9328-ESV100 saves the day:

In a packaging machine, this drive controls the film puller. If it goes down, you’re splicing film by hand, which drops output by 50%.
For a fan or pump application, the sensorless vector control allows for precise pressure regulation without the cost of a feedback encoder.
During a control panel rebuild, using a surplus EVS9328-ESV100 makes financial sense—it offers the same I/O footprint and firmware compatibility as a brand-new unit but at a fraction of the cost.

The Lesson: Verify the firmware version before swapping. While rare, a version mismatch between the old and new unit can cause communication hiccups with the PLC.

Quality Control Process (SOP Transparency)

1. Inbound Inspection
We treat every used or surplus drive like it’s contaminated until proven otherwise. First, we check for the OEM barcode and any signs of physical abuse—burn marks, cracked heat sinks, or leaking capacitors are instant rejects. For the EVS9328 series, we specifically look at the cooling fins; if they’re clogged with dust or debris, it goes straight to the cleaning bench.2. Live Functional Test
We don’t just power it on; we stress it.

Environment: Tested on a dedicated 240V AC bench with a resistive load bank.
Power-On: We monitor the LED status display for error codes during boot-up (should show “rdy” or “ini”).
I/O Test: We simulate a start signal via the digital input and verify the output voltage ramps up smoothly (0-240V) using an oscilloscope.
Load Test: We run the drive at 100% load for 4 hours, monitoring the heatsink temperature. If the thermal shutdown triggers prematurely, the unit is flagged.

3. Electrical Parameters
Using a Fluke 87V, we check the insulation resistance between the power terminals and the PE (Protective Earth) terminal. It must read >10 MΩ. We also verify the continuity of the internal braking resistor (if equipped).4. Final QC & Packaging
Once it passes, we reset the operating hours (if possible) and seal it in an anti-static bag with the manual (if available). We attach a QC Passed label with the test date. If you have specific firmware requirements, let us know—we can usually flash it to your requested version before shipping.

Installation Pitfalls Guide (“Lessons Learned” Voice)

1. The “PHF” Ghost
Firmware mismatch: While less common on this specific model, it does happen. If the new drive throws a PHF (Phase Failure) fault immediately on power-up, don’t panic. It might be detecting a missing phase on the input. Check the input wiring voltage stability. If the line voltage is noisy or sagging below 180V, the drive will trip. Honestly, this drive is picky about brownouts.2. The “Overcurrent” Surprise
Motor cable length: This is a classic. If you’re using long motor cables (over 50 feet/15 meters) without a choke or dV/dt filter, the reflected wave from the motor can fry the output IGBTs. If the drive trips on “OC” (Overcurrent) during acceleration, check your cable run. Keep it short or add filtering.3. The “No Display” Freakout
DIP switch/jumper error: Before you install it, take a photo of the DIP switches on the old unit. The EVS9328 has switches for selection between 1-phase and 3-phase input (if applicable to your region), and for setting the analog input type (0-10V vs 4-20mA). Set the new one exactly like the old one. If the display stays blank after power-up, it might be because the input voltage selector is wrong.4. The “Thermal Runaway”
Heat is the enemy. This drive is rated IP20. If you’re mounting it inside a control panel, ensure there’s at least 1 inch (25mm) of clearance above and below for convection cooling. Mount it on a grounded metal plate to use as a heatsink. If the panel AC is broken and the ambient temp hits 55°C, this drive will throttle back or shut down.5. The “Grounding” Gamble
ESD/Noise: This drive switches at high frequencies. If you get erratic behavior (random trips, PLC comms dropouts), check the grounding. Use a star-point ground if possible. Don’t daisy-chain the ground wires. A solid earth connection is non-negotiable for noise immunity.
