Functional Description
During a fast deceleration, the kinetic energy of the motor load is regenerated to the drive, charging the DC link capacitors.
When the VDC Lim Level is reached, the speed septoint is held, waiting for the DC link to go below VDC Lim Level.
When the DC link falls below this level, the speed setpoint is released and is ramped down using system ramp deceleration.
This sequence is run until the speed septoint reaches the user speed demand.
By Default, VDC Lim Level is set to the same value as the braking threshold.
This feature is run at a rate of 1 milli-second.
