6-40 Writing the User Program ECODRIVE03-FL*-04VRS
DOK-ECODR3-FL*-04VRS**-FK01-EN-P
JST - Jump and Stop
or
Target Instruction
With this command, the program jumps to the specified target location.
However, program execution stops there. The program continues only
when the voltage changes from '0' to '1' at the system input ‘Start.’ With
the new start signal, the program continues at the target location. This
command is used frequently to end a machining cycle. If the drive is in
motion, it is brought to a standstill by the programmed
acceleration/deceleration values. The remaining travel distance is stored
and executed after the next start. There is no loss of measurement, as
long as there was no change of operating mode or error message.
Continuous operation using the 'CON' command is disabled!
The output states are not changed by a 'JST' command. In multitasking
(see Section 8.7), a JST command results in a programmed stop in all
running tasks. Task 3 is not affected.
This corresponds to the system input: Stop.
JTK - Jump in Task
or
1 = Target Task 1
2 = Target Task 2
3 = Target Task 3
Target Instruction
This command can be used to influence program execution in one of the
other tasks. The program stops processing in the specified target task,
and the target task branches to the specified target instruction.
The command 'JTK_0100_2' that is called in Task 1 causes execution of
the Task 2 program to continue at instruction 100.
The command `JTK 0100 1´ in Task 1 has the same meaning as the
'JMP 0100' command.
The program proceeds to the next instruction following the time period of
one cycle.
