WARNING!
Do not 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.
￭ Parameter settings for external braking chopper and resistor
Disable the overvoltage control of the drive with parameter 30.30 Overvoltage control.
Disable parameter 43.06 Braking chopper function as parameter group 43 Brake chopper
is used for internal braking chopper and resistor only.
