Range 0 to MAX_RAMP_RATE s / (Pr 1.06 or Pr 2.39)
Default 10.000
Update rate Background read
The jog deceleration rate is only used when the drive is changing speed because the jog reference has changed or to stop from the jog reference. It
is not used to go from the jog to the run state. This prevents the fast ramps normally used with jog from being used when changing between running
and jogging.
