|
Induction motor
|
Sensorless vector control: 1. With V/f characteristic curve for constant torque → Default profile 2. With V/f characteristic curve for quadratically increasing torque → Energy-saving profile, e.g. for fans and pumps Sensorless slip control: 1. With V/f characteristic curve for constant torque → Default profile 2. With V/f characteristic curve for constant torque (6 f ranges) → Profile for individual special applications 3. With V/f characteristic curve for quadratically increasing torque → Energy-saving profile, e.g. for fans and pumps

Main protective functions of inverter
|
Thermal protection against power stage overheating Protection against short circuits between motor phases, overcurrent between output phases and ground, overvoltages on the DC bus, exceeding the speed limit. Safety function for: Overvoltage and undervoltage of the mains supply, mains phase failure with 3-phase power supply
