The Lenze I55AP240F20711K06S is a powerful and compact frequency inverter designed for 3-phase 400–480 VAC motor control up to 5.5 kW. It offers versatile control methods including V/f, sensorless vector, and synchronous motor modes, suitable for industrial applications like conveyors, pumps, and hoists. Featuring a built-in PID controller, extensive communication options, flexible I/O, and comprehensive safety features within an IP66-rated enclosure, this inverter delivers reliable and efficient performance in demanding environments.
Common Applications:
- Conveyor drives
- Traveling drives (e.g. winches, gantries)
- Pumps and fans
- Agitators and mixers
- Winding, forming, tool, and hoist drives
Key Features:
- Compact design (approx. 60 mm × 130 mm) supporting 5.5 kW / 7.5 HP at 400–480 VAC 3-phase input
- Variable speed control modes: V/f (linear & quadratic), VFCeco, sensorless vector, synchronous motor control
- Output frequency range: 0–599 Hz with selectable switching frequencies (2, 4, 8, 16 kHz)
- Built-in PID process controller and S‑ramps for smooth acceleration/deceleration
- Flexible I/O: 5 digital inputs, 1 digital output, 1 relay output, 2 analog inputs, 1 analog output
- Modular communication via CANopen, Modbus RTU, Modbus TCP, EtherCAT, EtherNet/IP, PROFINET, IO-Link
- Motor functions: DC braking, flight restart, brake control, slip compensation, automatic motor ID
- Integrated EMC filter, zero-clearance IP66 enclosure with conformal coating
- Safety protections: earth-fault, overvoltage, overcurrent, overtemperature, stall, and motor temperature (PTC) monitoring
- Certified to CE, UL, CSA, EAC, RoHS, ECODESIGN (EN‑50598)
- Multiple setup options: keypad, smartphone app (Wi‑Fi), or PC configuration tool
