Practical Application Cases of Lenze i510 (Directly usable for tender documents & selection reference)

> Core positioning: The i510 is a general-purpose basic drive supporting V/F and sensorless vector SLVC control. The 001S variant features on-board Modbus RTU/CANopen.

No built-in brake chopper, STO unsupported, no industrial Ethernet expansion available. It is preferred for light-duty loads with smooth start/stop and no high-precision positioning requirements.

Fall 1: Segmented Roller / Belt Conveyors for Logistics Warehousing (Most Popular Application)

Betriebsbedingungen

Independent roller conveyors in e-commerce warehouses and food production lines. Automatic speed regulation to prevent material blockage triggered by accumulated goods; each conveyor driven by a separate motor.

Leistungsbereich: 0.37kW～4.0kW, 3AC400V

Control scheme: PLC multi-drop network control via Modbus RTU. Photoelectric sensors detect downstream material presence to trigger upstream speed reduction or stop. Digital inputs handle fault reset and run enable; relay output for fault alarm.

i510 Advantages

1. Slim frame width (≤4kW models only 60mm) allows dense zero-clearance cabinet mounting
2. S-curve ramp prevents carton tipping and reduces mechanical impact on rollers
3. Built-in DC braking enables stable short-distance stopping
4. WLAN module + Lenze App enables on-site commissioning without cabinet disassembly

Selection Reminder

For frequent emergency stops and high-inertia loads: External brake resistor + external brake unit are mandatory (i510 lacks integrated brake chopper). Upgrade to i550 for heavy-duty continuous conveying.

Fall 2: Auxiliary Drives for Packaging Machinery (Material Feeding Lines, Wrapping Conveyors, Discharge Belts)

Betriebsbedingungen

Infeed belts, separating conveyors matched with horizontal flow wrappers and case packers; multi-speed switching to synchronize with main machine cycle.

Leistungsbereich: 0.25～2.2kW, single-phase 230V / three-phase 400V optional

Steuerungsoption 1 (Basic machines): Multi-speed control via digital inputs with 3~5 preset speeds

Steuerungsoption 2 (Automated machines): CANopen bus linkage to follow main machine speed

Matching Benefits

I/O resources perfectly meet auxiliary machine requirements: 5AUS / 1TUN / 2KI / 1 Relais. 0–10V analog input accepts speed reference from main equipment. Simplified parameter structure enables standardized templates for machinery manufacturers.

Caveat

If electronic cam, master-follower synchronization or high-precision spindle positioning is required, the i510 cannot be used; select i550 or servo drives instead.

Fall 3: Fans, Circulation Exhaust & Oven Circulation Fans (Energy-saving Constant Pressure Control)

Betriebsbedingungen

Constant temperature / constant air volume PID regulation for food drying tunnels, workshop ventilation and simple waste gas treatment systems.

Leistungsbereich: 0.75～11kW

Kontrollmethode: Built-in PID regulator; temperature/pressure transmitters connected to analog inputs for automatic speed adjustment; sleep energy-saving function available.

Value Highlights

VFC-Eco energy-saving mode optimizes operation for quadratic fan loads and reduces no-load power loss, delivering notable energy savings compared with direct-on-line contactor control.

> Notiz: For explosion-proof fan applications, explosion-proof motors and external certification are required. The i510 itself is not explosion-proof.

Fall 4: Mixer & Blenders for Light Materials

Betriebsbedingungen

Small powder blenders, water treatment chemical mixing tanks; continuous low-speed stirring and intermittent operation.

Leistungsbereich: 0.55～5.5kW

Kontrolle: Analog speed reference or bus command. Boost torque configured at startup to avoid stalling from settled materials; overload protection prevents jamming caused by blocked material.

Einschränkungen

Select i550 for high-viscosity media and heavy loads with sustained shock loads (z.B. asphalt, high solid-content slurries). The i510 suits light, homogeneous materials only.

Fall 5: Auxiliary Feed & Convey Mechanisms for Woodworking Machinery

Betriebsbedingungen

Feed belts for sliding tables, board infeed conveyors, discharge belts for sanders; smooth transportation to avoid surface scratches on panels.

Leistungsbereich: 0.37～3kW

Process Requirements

Low-speed startup and gentle ramp control with continuously adjustable speed. Multiplexed DI can acquire HTL frequency signal for basic line speed following.

> Wichtiger Hinweis: The i510 only supports simple frequency acquisition via digital inputs. No dedicated encoder card for precision synchronization. Choose i550 for synchronized cutting of precision wood panels.

Fall 6: Process Water Supply Centrifugal Pumps (Simple Constant Flow Control)

Betriebsbedingungen

Constant pressure control for cleaning equipment water supply and workshop process circulation water; single pump setup without complex pump rotation or redundancy logic.

Leistungsbereich: 1.5～7.5kW

Kontrolle: Built-in PID with pressure transmitter connected to analog input; dry-run protection and low-flow sleep function.

Ungeeignete Szenarien

Building secondary water supply and multi-pump cascading systems require higher-performance drives.

Fall 7: Light-duty Travelling Carts & Pallet Transfer Trolleys

Betriebsbedingungen

Workshop material transfer trolleys, simple pallet cross-shift mechanisms; forward/reverse two-speed operation with limit switch stop.

Leistungsbereich: 0.75～4kW

Kontrolle: Direction commands + multi-speed via digital inputs; limit switches trigger rapid stop. Suitable for short-distance, low-frequency movement.

Strict Prohibition

Do not use i510 for hoisting and lifting equipment. Without STO Safe Torque Off and safety functions, i550 STO variant is mandatory.
