Control

• Open loop vector control
• Speed or torque control
• Speed reference input: 0-10V, 0-20mA, 4-20mA, (-10 to +10V SM-I/O Lite option)
• 4 digital inputs- World (enable, run forward, run reverse, local/remote)- USA (not stop, run, jog, local/remote)
• Switching frequency: 3 (default) – 6 – 12– 18 kHz
• Output frequency 0 to 1500Hz
• Accel and Decel ramps (linear and S type)
• Positive logic control
• Serial communication - Modbus RTU RS485 via RJ45 connector- Baud rate 4800, 9600, 19200or 38400 bits per second
• DC injection braking as standard
• Dynamic braking transistor as standard
• Dynamic motor flux V/Hz for energy saving
• Quadratic motor flux V/Hz for fan and pump optimisation
