7.1.3. Interruption of Positioning (STP)
l Turning ON the STP input will stop the Motor in the middle of a positioning with the RS-232C
position command, Programmable Indexer, and Jog.
l Though the shipping set of deceleration of the STP input is to bring a sudden stop, you may alter
the its deceleration setting. (Refer to the parameter MD.)
l The STP input is only effective for positioning operations in the RS-232C position command,
Programmable Indexer and Jog. It is ineffective for the operation by the pulse train command
input or the analog command.

à The start commands for positioning such as RUN (Positioning start), HOS (Home
Return) and JOG (Jog) are ineffective while the STP input is ON.
à The STP input may not be accepted when the signal does not remain ON for 10 ms or
longer.
à When the Motor stops by the STP input, the IPOS output does not close in case of the
FIN format (parameter FW>0).
à When the acceleration set by the parameter MD is less than the parameter MA, the
Motor decelerates along the parameter MA.
à In case of analog command or torque command operation through the RS-232C
communication, the DC command will be cleared to zero when the STP input is ON.
