Switching Commands during Execution
TRQ
EX_POSING
TRQ will immediately switch to EX_POSING, and the control mode will change from
torque control mode to position control mode.
After TRQ has switched to EX_POSING, the EX_POSING command will be
executed without the acceleration/deceleration filter. To enable the accelera-
tion/deceleration filter, hold the TRQ operation by executing an NOP com-
mand or other commands. Then, when the Discharging Completed bit
(IW
0C, bit 0) turns ON, execute an EX_POSING command.
The value of the Position Reference Setting (OL 1C) when the motion command is
switched will be as follows.
09, bit 5 = 0)>
Incremental value = Target position − IL 14 (DPOS)
OL 1C = OL 1C+ Incremental value
09, bit 5 = 1)>
OL 1C = Target position
ZRET
The axis will decelerate to a stop in position control mode. When the axis stops, TRQ will
switch to ZRET.
Switched From Switched To Operation
TRQ EX_POSING
TRQ EX_POSING
Torque control mode Position control mode
TRQ EX_POSING
The speed will smoothly change.
(The speed at the time the motion com-
mand is switched will increase/decrease
until it reaches the target speed of
EX_POSING.)
The acceleration/deceleration filter
will be cancelled.
