Category: Others

Description

Technical Specifications:

Rated Power: 0.37 kW (0.5 HP)
Supply Voltage: Single Phase 200–240 VAC (+/-10%), 50/60 Hz
Rated Output Current: 2.2 A (at 240 V)
Overload Capacity: 150% for 60 seconds, 180% for 5 seconds
Control Method: V/f, VFC (Voltage Flux Control), Sensorless Vector
Switching Frequency: 4 kHz to 16 kHz adjustable
Safety Function: STO (Safe Torque Off) according to EN ISO 13849-1PLd / SIL 2
Communication: CANopen onboard; optional EtherCAT, PROFINET, EtherNet/IP

Functional Characteristics: Integrated brake management (for holding brakes), VFC eco energy saving mode, 4 digital inputs / 1 digital output, 1 analog input / 1 analog output, PID controller built-in.

Performance Parameters: Speed Range: 1:100 (sensorless vector); Starting Torque: 150% at 0 Hz (with VFC); Efficiency: > 97% (typical); Ambient Temp: -10°C to +45°C (derating to +55°C).

Material Composition: Chassis: Flame-retardant ABS/PC blend (UL94 V0); Heat Sink: Aluminum extrusion; PCB: FR4 with conformal coating (optional); Capacitors: Metallized polypropylene film.

Structural Features: Book-size form factor, removable terminal strips, LED status indicators, front keypad option, IP20 protection (cabinet mounted), natural convection cooling for < 0.75 kW units.

Working Principle: The drive rectifies incoming AC to DC, then uses insulated gate bipolar transistors (IGBTs) in a PWM inverter bridge to synthesize variable voltage/frequency AC output, regulating motor magnetic flux and torque via closed-loop or sensorless algorithms.

Advantages: Plug-and-play commissioning via Lenze software, compact footprint saving panel space, integrated safety and energy functions, high reliability in intralogistics environments.

Applicable Industries: Intralogistics (conveyors, palletizers), Packaging machinery, Plastics extruders, Door/gate automation, Woodworking machines.

Model Series: Lenze 8400 StateLine series.

Installation Requirements: Mount vertically on 35 mm DIN rail or screw-fixed; maintain >50 mm clearance above/below for airflow; install in grounded metal enclosure; ensure input fusing 10 kA interrupt rating.

Usage Precautions: Verify motor insulation before connection; STO terminals must be wired per safety circuit design; do not touch terminals with power on (DC bus voltage present up to 400 VDC); commission brake control settings to prevent load drop.
