1 Introduction
1.1 Generally
The Speed Commander V5 is a static frequency inverter with DC-link voltage for
continuously variable speed control of AC motors.
• Vector modulation and 16bit microprocessor
• Display for
- Motor frequency, current, DC link voltage, parameters, error codes, positions and more.
• Galvanic separated control inputs for:
- Motor frequency, Motor voltage (torque)
- Right rotation
- Left rotation
- STOP (Brake function)
- OFF (Powerless motor wires)
- STOP (DC-Braking)
• Programmable relay and NPN outputs.
• Special V/F curves for ventilation and pump operation.
• Power range from 0,75 kW - 1x230 VAC / to 22 kW - 3x400 VAC
• Integrated software programs for:
- PI-regulation (Pressure , temperature etc.)
- Positioning
- Digital synchronous drive
- Torque limiting / Supervision
