Switching Commands during Execution

VELO

INTERPOLATE

VELO will switch to INTERPOLATE when the axis stops after deceleration, and the con-
trol mode will be changed from speed control mode to position control mode after the axis
deceleration is completed.

<Change in Position Reference Setting (OL

1C) during Deceleration>

• In Incremental Addition Mode (OW

09, bit 5 = 0)

Any change in the Position Reference Setting (OL

1C) will be ignored.

• In Absolute Mode (OW

09, bit 5 = 1)

The change in Position Reference Setting (OL

1C) will be output as soon as the first

high-speed scan after INTERPOLATE execution starts.

Do not change the Position Reference Setting during deceleration unless it is
absolutely necessary.

FEED

VELO will immediately switch to FEED, and the control mode will be changed from
speed control mode to position control mode. The moving amount stored in the accel/
decel filter will be reset to 0.

FEED switched from VELO starts its operation with the empty accel/decel fil-
ter. Therefore, when the accel/decel filter is set for FEED command, the
speed will not smoothly change, and the distribution will be started from the
state Speed = 0 (see (1).) To change the speed smoothly, do not set the filter
for FEED command (see (2).)

The speed will smoothly change.

The speed at the time the motion command is

switched will increase/decrease until it reaches

the FEED target speed.
