Function
Acceleration ramp-down constant. This specifies
the time in milliseconds required to ramp the acce-
leration down from maximum acceleration to 0 (i.e.
normally to constant maximum velocity). If set to
0, this will default to the same value as par. 32-86.
NB!:
A changed setting of JERKMIN2 is execu-
ted after the next movement command
(POSA, POSR, CVEL, or MOTOR STOP) and
used for the calculation of the acceleration. Thus it
is possible in NOWAIT ON mode with a repeated
POSA command to adapt during a movement
online (i.e. without stop) the movement to new
definition.
See also "Limited Jerk" in chapter "Function and
Examples" and par. 32-86.

Range

Function
Deceleration ramp-up constant. This specifies the
number of milliseconds required to ramp the dece-
leration up from 0 to maximum deceleration.
NB!:
A changed setting of JERKMIN3 is execu-
ted after the next movement command
(POSA, POSR, CVEL, or MOTOR STOP) and
used for the calculation of the acceleration. Thus it
is possible in NOWAIT ON mode with a repeated
POSA command to adapt during a movement
online (i.e. without stop) the movement to new
definition.
NB!:
If JERKMIN3 set to 0, this will default to
the same value as par. 32-86.

JERKMIN4
Range
0 ... MLONG [ms]
Function
Deceleration ramp-down constant. This specifies
the number of milliseconds required to ramp the
deceleration down from maximum deceleration to 0
(i.e. normally to 0 velocity).
NB!:
A changed setting of JERKMIN4 is executed after
the next movement command (POSA, POSR, CVEL,
or MOTOR STOP) and used for the calculation of
the acceleration. Thus it is possible in NOWAIT ON
mode with a repeated POSA command to adapt
during a movement online (i.e. without stop) the
movement to new definition.
