All Commands from ACC to #INCLUDE
In the following section all commands are listed in alphabetical order and described in detail with syntax
examples as well as short program samples.
ACC
Summary
Setting acceleration for motion commands.
Syntax
ACC a
Parameter
a = acceleration
Description
The ACC command defines the acceleration for the next motion command (speed
control, synchronizing or positioning). The value will remain valid until a new
acceleration value is set, using the ACC command. The value is related to the
parameters 32-81
Shortest Ramp
and 32-80
Maximum Velocity
as well as 32-83
Velocity Resolution
.
NB!:
If acceleration has not been defined previous to a motion command, then the
maximum acceleration will be the setting of par. 32-85
Default Acceleration
.
NB!:
If the MCO 305 is used to control FC 300, then the ramps should always set via the
option card and not in the FC 300. The FC 300 ramps must always be set to
minimum.
