The axis will decelerate to a stop in speed control mode, and the control mode will be
changed from speed control mode to position control mode when the axis stops.
TRQ will switch to INTERPOLATE when the axis stops after deceleration.
INTERPOLATE
<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 the 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.

TRQ will immediately switch to FEED, and the control mode will be changed from
torque/thrust control mode to position control mode.
 FEED switched from TRQ starts its operation with the empty accel/decel filter.
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).)
