There are two types of ramp-function generator:
● Basic ramp-function generator with
– Acceleration and deceleration ramps
– Ramp for quick stop (OFF3)
– Tracking configurable via parameter p1145
– Setting values for the ramp-function generator
● The extended ramp-function generator also has
– Initial and final rounding off
Note
The ramp-function generator cannot be frozen (via p1141) in jog mode (r0046.31 = 1).
