Function
Use this parameter while S--Curve Acc/Dec (G47.1) is active to select the
desired acceleration rate. A 0.0 value in this parameter disables Acc/Dec
for the applicable axis.
If a large value is entered here, the axis accelerates rapidly. A small value
results in a more gradual acceleration.
Important: If you attempt to run the axis with a high gain (refer to the
Initial Gain parameter in chapter 7), higher values are generally required
for this parameter to avoid getting the “EXCESS FOLLOWING ERROR”
message.
Important: This parameter is not for use with manual jogged motion.
