These bits are provided for control by logic input terminals for external ramp selection (see parameter 2.10 and 2.20).
Used as a ramp rate controller for controlled stop.
During mains loss, if the DC bus voltage collapses beyond the level set in parameter 6.48 a DC link controller operates, the output of which
changes the ramp rate. The controller can be disabled by setting the detection level in parameter 6.48 to 0. As the controller regulates the link
voltage, the motor deceleration increases to keep the DC bus at a maximum level to achieve the fastest possible controlled stop. When the
motor is stopped the controller ceases to operate. Controller gains can be adjusted using parameters 2.46 and 2.47. If the mains is re-applied
during the stop the controller still operates to zero speed, the mains loss bit 6.48 remains set and can only be reset by giving a drive reset.
Used as a ramp rate controller for preventing braking resistor overload trip. See parameter 2.04 for more information.
