Chapter 1 - Function and Features (Overview)

The AV-300i is a field-oriented vector Drive with excellent speed control properties and a high torque.
Available control modes are:
- Field oriented with speed sensor
- Field oriented without speed sensor (Sensorless vect mode)
- V/f control
Space vector modulation keeps the noise level to a minimum.
- Output voltage up to 98% of input voltage
- Self tuning procedure for current, flux and speed regulators
The Drives are fitted with IGBTs (insulated gate bipolar transistors).
The output is protected against ground fault and phase to phase output short.
Regulator power supply via switched-mode power supply unit from the DC Bus circuit. Power supply backup in
the event of short-term voltage dips.
Galvanic isolation between control section and command terminals.
Analog inputs designed as differential inputs.
Simple operation of the drive
- via the terminal strip
- via the user-friendly keypad
- via the PC program supplied and the RS485 serial interface
- via a fieldbus connection (optional): PROFIBUS-DP or GENIUS.
- Toolbox configuration tool
Fault register storing the last ten fault alarms with the associated lifetime.
Overload control
Engaging a running motor
Three freely configurable analog inputs on the standard device
Expansion of the analog / digital outputs and analog / digital inputs via option cards
Reference value entry and actual value display as a percentage of a user-defined dimension
Speed and torque current regulation possible
Adaptive speed regulation
Speed-related alarms
Motor potentiometer function (Increase/Decrease speed by command)
Jog operation
8 internal speed reference values
4 internal ramps
PID control
Controlled stop in case of AC mains power loss.
