Short Description Acceleration Ramp


This variable defines the acceleration ramp for the velocity control loop (in msec), in reference to the maximum velocity (the larger value of VLIM and VLIMN). The acceleration ramp is only used for command changes resulting in a velocity increase (acceleration). DEC is used for braking (deceleration). For a command step from 0 to VLIM or VLIMN, the ramp generator generates a stepped ramp (with steps of 250 microseconds) that is completed within the set ACC time.

From firmware 3.41 the ramp can be set by different units. Details are shown at parameter ACCUNIT .

REV 2.3:
Put ACC to the minimum delay if a P-position ( EXTPOS = 1,3,4 ) controller is used.
