Caution:
This command must be used with the
utmost prudence
, since movement speed is very high.
Although the STE command is not an alias, the syntax STE.1+=1000 or STE.1-=1000 are allowed, in order to
make
relative
jump movements, because an absolute jump movement can be dangerous if the motor is far
away from the position to reach.
Examples:
STE.1+=1000
;
Relative
jump movement. the motor realizes a jump movement of 1000 increments
in the positive direction.
STE.1=1000
;
Absolute
jump movement. The motor makes a jump movement from its actual
position to the position of 1000 increments.
13.3.9 BRK and STP commands
The
BRK
command (
BR
a
K
e) stops a movement with the deceleration programmed in parameter K206. It is
also used with infinite rotary movement (refer to
).
The
STP
command (
ST
o
P
) behaves the same way as BRK but the deceleration is infinite. The braking is then
very sudden. This command is to be used only in case of emergency.
Caution:
The sudden deceleration set with the STP command can damage the mechanical parts of the
system.
Note:
BRK and STP commands do not stop the sequence; thus, the movements defined in a sequence
will be executed.
13.3.10 Parameters defining units scales
Parameter
K50
defines the unit scale movements:
Parameter K50:
The POS, SPD and ACC commands are used respectively to determine a position to reach, a speed or an
acceleration. The arguments of these commands must be given in a unit called
user increment
