7.4.5 Forced Stop, Deceleration Stop (F0) Instruction
Pulse output control instruction (F0)
- Forced stop and deceleration stop is executed by F0(MV) instruction in combination with the special
data register DT90052. Once this instruction is executed, the settings will remain until this instruction is
executed again.
[Example ] Performing the forced stop of pulse output.
For CH0
For CH1
[Example 2] Performing the deceleration stop of pulse output
For CH0
For CH1
Note:
- Performing a forced stop may cause the elapsed value at the PLC output side to differ from the elapsed
value at the motor input side. Therefore, you must execute a home return after pulse output has
stopped.
- When executing the forced stop (pulse output stop) with the pulse output control instruction (F0), the
operations being executed with various instructions are cancelled and the pulse output is immediately
stopped. When the forced stop request flag (bit3 of DT90052) is on, instructions cannot be executed.
- When executing the deceleration stop with the pulse output control instruction (F0), the operations
being executed with various instructions are cancelled and the deceleration operation starts. When the
deceleration stop request flag (bit5 of DT90052) is on, instructions cannot be executed. As for the data
table control instruction (F174), the operation is similar to that of the forced stop.
- After the execution of the forced stop or deceleration stop, pulses are not output unless the execution
condition of each pulse output instruction (F171 to F177) changes from OFF to ON.
