7.2 Motions After Switching Motion Commands
7.2.1 Switching from POSING
7-8
POSING
ZSET
POSING will immediately switch to ZSET, and positioning will continue.
In actual operation, set the zero point by executing ZSET in the positioning
completed status.
VELO
POSING will immediately switch to VELO and the control mode will change from posi-
tion control mode to speed control mode. The moving amount stored in the acceleration/
deceleration filter will be reset to 0.
After POSING has switched to VELO, the VELO command will be executed
without the acceleration/deceleration filter. To enable the acceleration/decel-
eration filter, hold the POSING operation by executing an NOP command, or
other commands. Then, when the Discharging Completed bit (IW
0C, bit
0) turns ON, execute the VELO command.
TRQ
POSING will immediately switch to TRQ and the control mode will switch from position
control mode to torque control mode. The moving amount stored in the acceleration/decel-
eration filter will be reset to 0.
After POSING has switched to TRQ, the TRQ command will be executed
without the acceleration/deceleration filter. This is because TRQ is a motion
command for which the acceleration/deceleration filter is disabled.
