14 PLC Help Function
14.2 Manual Speed Command
 When this function is valid, MST or dwell commands are executed the same as in the normal automatic operation.
Therefore, if MST is commanded to the same block as the movement block, the program does not move to the next block
before the MST command is completed.
 The manual speed is clamped when the entered speed exceeds the clamp speed.
 In the creep control of the dog type reference position return, the "reference position return creep speed" is applied regard-
less of the entered manual speed.
 To stop the movement by handle and changed to the automatic operation, turn OFF the "Manual feed command valid" sig-
nal and the handle mode, and then execute the cycle start with the memory mode ON.
 If the cutting override is "0", the movement occurs by the manual speed when other than JOG manual speed command is
given. No movement occurs in the JOG mode.
 In the synchronous tapping, cuttings follow the commands in the program. The manual speed command does not effect on
the operation. Neither stopping the handle move nor turning OFF the JOG mode stops the operation.
 When the parameter "#1247 set19/bit1" (thread cutting operation selection when the manual speed command is valid) is
set to "1", the axis moves in accordance with the program command while the thread cutting is in progress or until the next
block's end point of where the thread cutting is completed (the G33 mode has ended).
Even if the handle is stopped or the JOG is turned OFF while in this movement, the axis will not stop until it moves to the
next block's end point of where the thread cutting is completed.

 If the manual speed command valid signal is turned OFF while executing this function, this function becomes invalid even
during the axis is traveling. However, in the synchronous tapping or thread cutting, the manual speed command is kept
valid until the end of these processes: turning OFF the "Manual speed command valid" signal does not effect on these pro-
cesses.
When the parameter "#1247 set19/bit1" is set to "1", even if the manual speed command is turned OFF while executing the
thread cutting, this signal is valid until the next block's end point of where the thread cutting is completed.
