Switching Commands during Execution
TRQ
STEP
TRQ will immediately switch to STEP, and the control mode will change from torque con-
trol mode to position control mode. The moving amount stored in the acceleration/deceler-
ation filter will be reset to 0.
After TRQ is switched to STEP, the STEP command will be executed without
the acceleration/deceleration filter. To enable the acceleration/deceleration fil-
ter, hold the TRQ operation by executing an NOP command or other com-
mands. Then, when the Discharging Completed bit (IW
0C, bit 0) turns
ON, execute a STEP command.
ZSET
The axis will decelerate to a stop in position control mode. When the axis stops, ZSET
command execution will start.

The speed will smoothly change.
(The speed at the time the motion com-

until it reaches the target speed of STEP.)
The acceleration/deceleration filter will be
cancelled.

In position control mode, the axis
will decelerate to a stop from the
speed when the motion command
is switched.
A machine coordinate
system will be constructed
where the axis stops after
deceleration.
