• 4 modes of operation: V/f Control Open-Loop Vector Closed-Loop Vector Cosed-Loop Vector PM • Direct control of motor brake and motor contactor • Short floor operation • Door opening control • Hardware baseblock (EN81-1 Compliance) offers the possibility to eliminate one motor contactor • Auto-tuning at standstill: Motor Equivalent Circuit Data (No-Load current, Slip, Resistance and Saturation Coefficient) are measured by the inverter • No need to absolute encoders for PM motors. The Initial Magnetization Estimation function detects the position of the magnetic pole when the power is turned on. • Connectivity to all popular field busses • PC configuration and commissioning tool DriveWizard • 4 output relay • Advanced IGBT protection: 5-level over current protection before current failure occurs • Cooling fan control for silent operation • S-curve operation realizes smooth acceleration and deceleration. • Carrier frequency up to 15kHz for quiet operation • Copy function to save setting parameters in keypad • Inverter size (kW) can be selected same as motor kW rating • Zero-servo function and the Starting Torque Compensation control realize smooth start-ups. |
