NOTICE
When set to [2] Local, the drive starts with this setting
again after a power-down.
Select this option to enable the FFACC factor in parameter 32-66
Acceleration Feed-Forward. Enabling FFACC reduces jitter and
makes the transmission from the motion controller to the control
card of the drive faster. This leads to faster response times for
dynamic applications and position control. For more information
about FFACC, see VLT® Motion Control MCO 305 Operating
Instructions.
