Set Speed Feed (FEED)
Executes fast feed in an unbounded direction at a designated accel/decel time constant
and a designated fast feed speed. The fast feed speed can even be changed during
operation. This function sets NOP (=0) into the motion commands (OWC020), and
then decelerates to a stop.
Detailed Description
The order of operations in the set speed feed is shown below.
1. Set initial fixed motion parameter and motion setting parameter values
to match the customer's machine.
2. Select the position control mode (PCON).(bit 2 of OWC000)
Sets the fast feed speed (OLC022 or OWC015).
3. Set the motion setting parameters used in set speed feed (FEED).
4. Turn the RUN command (Bit 0 of OWC001) ON.
5. Set set speed feed (FEED =7) in the motion commands (OWC020).
6. Set Speed Feed (FEED) Operation Start
