speed limit
12.20.5.1 DC link buffering
An axis/spindle can buffer the DC link by means of generator-mode braking. This function can
be selected through appropriate parameterization of 611D machine data and activation of
generator operation by programming commands.

Actual speed value
When the DC link voltage drops below the minimum threshold value set in drive MD 1631, the
axis/spindle concerned switches from position-controlled or speed-controlled operation into an
operating mode controlled by the DC link. When the drive is braked (through input of speed
