Industry Applications
Automotive Manufacturing Industry
Essential in automotive plants worldwide for electric monorail
overhead conveyors transporting engine blocks, car doors, and
components. IP65 protection prevents damage from oil stains and
metal dust. Distributed installation shortens motor cables in
sprawling plants, reducing wiring costs and signal interference.
Plug-and-play technology minimizes production line downtime during
setup. Also controls scissor lifts for vehicle maintenance and
component hoisting.
Intralogistics Industry
Used in cross-border e-commerce fulfillment centers and bonded
warehouses. Warehouse rotary tables sort international parcels with
adjustable rotation speeds. In cold chain warehouses, scissor lifts
handle frozen container loading/unloading outdoors with IP65
protection against moisture. Plug-and-play design enables quick
maintenance without delaying cargo turnover. Distributed
installation eliminates cluttered cables on warehouse floors,
improving operational safety.
Plastic Processing Industry
Commonly used with extruders in injection molding factories and
plastic pipe plants. Provides stable motor speed for uniform
extrusion of plastic melts. IP65 protection seals out plastic dust
and oil contaminants. Distributed wall-mounted design saves
valuable floor space in compact layouts. Commissioning requires no
complex wiring, allowing efficient parameter adjustments during
product changeovers.
Packaging Industry
Standard in bottle-filling lines at wine factories and snack
packaging facilities. Adjusts filling speed for different bottle
sizes to prevent spillage. Controls conveyor speed for bag-sealing
machines with precise positioning. IP65 protection prevents water
damage during high-pressure cleaning in food processing plants.
Plug-and-play technology enables quick parameter switching between
packaging formats without repeated wiring or debugging.
General Manufacturing Industry
Suitable for small hardware factories and medical device component
plants. Synchronizes conveyor speed with machine tool processing
rhythms in assembly lines. Sensorless vector control ensures smooth
operation for precision part transport, avoiding collisions.
Plug-and-play commissioning allows ordinary workers to perform
maintenance easily. IP65 protection withstands dust in typical
factory environments.
Frequently Asked Questions
Q: I'm in Europe, and my motor is a 4-pole 5.5kW model. Will a
same-power inverter be sufficient?
A: For 4-pole motors in Europe, consider a 7.5kW model for
heavy-load startup equipment like mixers or extruders. For light
loads like conveyors, 5.5kW works with extended acceleration time.
Q: I'm in Dubai and want to install this inverter outdoors. Can the
IP65 protection withstand desert conditions?
A: IP65 protects against sand and heavy rain, but add weekly
compressed air cleaning of heatsinks and install a sunshade for
temperatures reaching 50℃.
Q: I purchased from China and my shipment got stuck in Brazilian
customs demanding RCM certification.
A: CE isn't recognized in Brazil. Request official INMETRO
certification documents from Lenze through your supplier for
customs clearance.
Q: I'm in the US. After installation, the terminals can't fit our
12AWG thick cables.
A: Request a high-current terminal kit from your supplier. Specify
"North American wire gauge" when ordering to get the matching
terminal model.
Q: I'm in rural India with wild grid voltage fluctuations causing
undervoltage alarms.
A: Enable undervoltage ride-through function and extend tolerance
time to 2 seconds. This handles most voltage dips without needing a
stabilizer.
