Safety

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.

• The most versatile of the BMR frequency converter – the power solution for all kinds of spindles • Variable DC-link-voltage for optimum spindle voltage, thereby the best spindle control and running characterstics and lowest possible spindle temperature rise. • In most cases, sinusoidale filters or output chokes are not necessary, also low-voltage spindles can be operated without any problems • Galvanic isolation of the I/Os from the mains and spindle connections • Integrated brake chopper resistor 200 W • Automatic spindle braking when mains power off during operation • Pulse blocking, optional as safe torque off • Available as control cabinet version (SSE) with optional operating panel, also as desk-top unit or 19"-version
