SSU.5.3.1 EMERGENCY ACCELERATION LIMIT
To filter the velocity command in an emergency stop, set SP70 -F01610- to "1".
An emergency stop is the one requested by activating the Halt function, by deactivating the
SpeedEnable, or the one due a Drive malfunction.
SSU.5.3.2 RAMP GENERATION
For this type of velocity command filter, set SP80 -S00349- = 0 and SP100 -F01611- = 1
The action of this Ramp Generator is divided into three velocity sections.
In each one of them, the acceleration can be limited to a different value.
From 0 rpm to SP61 Acceleration limited to SP60.
From SP61 to SP63 Acceleration limited to SP62.
And from SP63 on Acceleration limited to SP64.
