Frequency converter with safety function SFU 0303STO

digital displayPWMdesktop

SFU 0303STO • The power solution for all kinds of spindles • Highest efficiency in spindle drive with lowest power losses in spindle, due to adjustable intermediate voltage circuit and 28,5 kHz PWM • Powerful spindle drive with high output power reserves • High flexibility because of various I/Os and enclosure options • Oversized on-board 200W chopper-resistor for powerful braking and shortest cycle times This frequency converter offers an extended range of safety functions and thus complies with the requirements of EN 60204-1 and IEC 61800-5-2. In detail, the inverter is equipped with a Safe Torque Off (STO), a safety function to prevent unexpected start-up. This STO function corresponds to stop category 0.
