Note) Note that the position control starting input will be disregarded even if it is turned on during acceleration.
Precautions during programming
When the same channel is described in a normal program and interrupt program both, do not execute them at
the same time.
This instruction cannot be executed when the corresponding control flag to the channel started is on.
If rewriting during RUN is performed during pulse output, pulses more than the setting may be output.
As for the position control starting input, only the rising edge (ON) is detected.
The instruction cannot be started when the deceleration stop request flag is on.
Note that the methods to stop the pulse output in this instruction are only any of the following operations:
Turning on the position control starting input (position control starting flag), requesting the deceleration stop
and executing an emergency stop.
The target speed cannot be changed with this instruction.
When the instruction is started during the interrupt program, specify the execution in the interrupt program
with the control code.
