NB!:
Parameter Jerk Duration JERKMIN it is not
implemented in the velocity axis
parameter dialog field and must be set
therefore in the program, e.g.
SET JERKMIN 100 // time in ms until the
// maximum acceleration is reached
SET RAMPTYPE 2
// movement profile with limited jerk
32-83 Velocity Resolution
VELRES
Range
1 – 10000
Function
The Velocity Resolution VELRES defines a relative
size for the velocity values of the motion com-
mands and parameters. The information concer-
ning speed and acceleration can then be made in
whole numbers in relation to this scaling. The value
100 means that the information in the commands
are related to 100, thus in percent.
32-84 Default Velocity
DFLTVEL
Range
1 – p. 32-83 VELRES
Function
Default Velocity indicates the default velocity which
is always used when no velocity is defined in the
process set. This value refers to the Velocity
Resolution VELRES.
32-85 Default Acceleration
DFLTACC
Range
1 – p. 32-83 VELRES
Function
Default Acceleration indicates the acceleration used
when no explicit statements have been made. This
statement is made in relation to par. 32-81 Shor-
test Ramp and refers to the par. 32-83 Velocity
Resolution .

33-0* Home Motion
Use following parameters to specify behavior for
home run and home motion:
33-00 Force HOME
HOME_FORCE
Option
Home run is not forced
Home forced
Function
0 = After being turned on the current position is
valid as the real zero point.
1 = After turning on the FC300 and after changing
axis parameters a forced tracking of the home
position must be made before a motion com-
mand is executed directly or by the program.
If this parameter is set to [1], then movement to
the home position must be completed before any
other positioning movement can be completed.
For a motion command that is not executed with a
terminated home run the error 106 is triggered.
NB!:
For safety reasons and to avoid false
positioning the parameter should always
be set to [1] and thus forcing tracking of
the home position. However, in this case it is
necessary to consider that all programs must
complete a HOME command before the first motion
command in order to receive perfect functioning.
