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 (BRaKe) stops a movement with the deceleration programmed in parameter K206. It is
also used with infinite rotary movement (refer to §13.3.3
).
The STP command (SToP) 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. The
