Operation

PHASE

NOP

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.
PHASE will switch to NOP when the axis stops after deceleration.

POSING

PHASE will immediately switch to POSING, and the control mode will be changed from
phase control mode to position control mode. The moving amount stored in the accel/
decel filter will be reset to 0.
The value of the Position Reference Setting (OL

1C) when the motion command is

switched will be as follows.

<In Incremental Addition Mode (OW

09, bit 5 = 0)>

Incremental value = Target position

− IL

14 (DPOS)

OL

1C = OL

1C+ Incremental value

<In Absolute Mode (OW

09, bit 5 = 1)>

OL

1C = Target position

POSING switched from PHASE starts its operation with the empty accel/decel
filter. Therefore, when the accel/decel filter is set for POSING 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 POSING command (see (2).)

Speed control mode

In speed control mode, the axis will

decelerate to a stop from the speed when

the motion command is switched.

Distribution will start from the state Speed = 0

since the accel/decel filter is empty.

The speed will smoothly change.

The speed at the time the motion command is

switched will increase/decrease until it reaches

the POSING target speed.

The accel/decel filter will be cancelled.
