Fig. 12.24 Restarting speed after speed change made during position control
(4) When the speed is changed by setting "
Cd.14
New speed value" to "0",
the operation is carried out as follows.
•
A deceleration stop is carried out, and the speed change 0 flag
(
Md.31
Status: b10) turns ON.
(During interpolation control, the speed change 0 flag on the reference axis
side turns ON.)
•
The axis stops, but "
Md.26
Axis operation status" does not change, and
the BUSY signal remains ON. (If a stop signal is input, the BUSY signal
will turn OFF, and "
Md.26
Axis operation status" will change to
"stopped".)
In this case, setting the "
Cd.14
New speed value" to a value besides "0"
will turn OFF the speed change 0 flag (
Md.31
Status: b10), and enable
continued operation.
