Technical data
380…480 V drives
500…600 V drives
WARNING!
Never use a brake resistor with a resistance below the minimum value
specified for the particular drive. The drive and the internal chopper are not able to
handle the overcurrent caused by the low resistance.
Symbols
R
MIN
–
Minimum allowed resistance of the braking resistor.
R
MAX
–
Maximum resistance allowed if maximum braking torque is necessary.
