Jump Instruction - Mitsubishi Electric MELSEC iQ-F Series FX5 User Manual

JUMP instruction

The JUMP instruction is used to jump to the positioning data No. set in the positioning data during Continuous positioning
control or Continuous path control.
The following two JUMP instructions can be used.
JUMP instruction
Unconditional JUMP
Conditional JUMP
By using the JUMP instruction, implementing the same positioning control repeatedly and selecting positioning data No. or
implementation conditions are enabled when Continuous positioning control or Continuous path control is performed.
Operation
■When the unconditional JUMP is used
The JUMP instruction is unconditionally executed and the operation jumps to the positioning data No. set in [Da.9] Dwell time.
■When the conditional JUMP is used
The block start condition data is used as the execution condition of the JUMP instruction.
• When block positioning data (No.7000 to 7004) is started, the condition data of each block is used.
• When the positioning data No.1 to 600 are started, the condition data of the start block 0 is used.
• If the implantation condition set in [Da.10] M code of the JUMP instruction is satisfied, the JUMP instruction is implemented
to jump to the positioning data No. set in [Da.9] Dwell time.
• If the execution condition set in [Da.10] M code of the JUMP instruction is not satisfied, the JUMP instruction is ignored and
the next positioning data No. is executed.
Restrictions
• When using a conditional JUMP instruction, establish the execution conditions of the JUMP instruction by when the
positioning data whose number is four number before the positioning data No. of the JUMP instruction is executed. If the
execution conditions of the JUMP instruction are not established by the time, the processing for when execution conditions
are not established is performed. (During the implementation of the continuous path control or continuous positioning
control, it will calculate the positioning data of the positioning data No. four items after the current positioning data.)
• The positioning control such as the one keeps looping until the conditions are satisfied cannot be implemented only using
the conditional JUMP instruction. For the target of the JUMP instruction, specify the positioning data whose control method
is other than the JUMP instruction and NOP instruction.
Description
When no execution condition is set for the JUMP instruction (when 0 is set as the condition data No.)
When implementation conditions are set for the JUMP instruction (The conditions are set in the condition
data used with Advanced positioning control.)
