If this parameter is zero then ramp hold only is applied when the drive is not active and until the end of the post-brake release delay to ensure that the
speed reference remains at zero until the brake has released. If this parameter is set to one the position controller (see menu 13) is also enabled
(Pr 13.10 = 1) and the local position reference source is selected (Pr 13.04 = 4(LocAL)) during the period when ramp hold is active. Provided the
default, non-absolute mode, is selected the position controller can help to limit the movement of the motor when the brake is released. When Pr 12.49
is changed from one to zero Pr 13.04 and Pr 13.10 are automatically set to zero.
