14.4 Sequences handling
A sequence of commands can be memorized in the controller, it is called a user sequence. A sequence may
contain up to 8190 lines for a DSC2P and DSC2V or 4095 lines per axes for a DSCDP, DSCDL and DSCDM.
The sending of commands or sequences, as well as all communications with the controller are usually realized
with ETEL Tools graphical interface software.
14.4.1 Stop a sequence: HLT, HLB, HLO
The three commands stop the movement of the motor as well as the execution of the user sequence.
The HLT command (HaLT sequence and movement) stops the movement with the maximum deceleration that
the controller can supply and interrupts the current sequence execution.
Caution: The sudden deceleration that the HLT command provokes may seriously damage the mechanical
parts of the system.
The HLB command (HaLt sequence and Brake) stops the movement without overrunning the authorized motor
maximum deceleration defined in parameter K206 and interrupts the current sequence execution.
The HLO command (HaLt sequence and power Off) stops the movement with the maximum deceleration that
the controller can supply, interrupts the current sequence execution and switches off the power in the motor
phases (PWR.1=0).
Caution: The motor may keep moving for a while, depending on the system's moving part inertia.
It is advised to use HLO command only if the controller is set with a relay which short-circuits the
motor phases when the power is switched off, in order to have a magnetic brake.
14.4.2 Group of axes
To send the same command to several axes, the simplest way is to use the following syntax (refer also to §6.):
<cmd_name>. (<axis1>,<axis2>,...,<axisn>) [<operator>] =[<P1>] [,<P2>]
Example:
POS.(1,2,7,30) = X1.1
14.4.2.1 Mask of axes
It is also possible to define a mask with several axes, using the % symbol.
Let's take as example the axes 1 and 4; they give in binary: 10010; this is 18 decimal or 12 Hexadecimal
Examples:
POS.%18 = X1.1
or
POS.%0x12 = X1.1
Command Comment Read parameters
HLT.<axis> Stops the motor with an infinite deceleration and the sequence. -
HLB.<axis>
Stops the motor without going over the authorized maximum acceleration programmed in
parameter K206 and the sequence.
K206
HLO.<axis> Stops the motor and switch off the power in motor phases (PWR.1 = 0) and the sequence. -
