5 DATA USED FOR POSITIONING CONTROL
Pr.43 External start function selection
Set which function to use the external start signal with.
0 : External positioning start ............... Carry out positioning operation with
external start signal input.
1 : External speed change request ..... Change the speed of the positioning
operation currently being executed with the
external start signal input.
In this case, set the new speed value in
" Cd.16 New speed value".
2 : Skip request ................................... The positioning operation currently being
carried out is skipped with the external start
signal input.
POINT
" Cd.25 External start valid" must be set to validate the external start signal.
Pr.44 Near pass mode selection for path control
Set the method to carry out control between positioning data items during
continuous path control of the AD75 interpolation control.
0 : Positioning address pass mode... The address designated in the "positioning
data" is passed, but the speed output when
the corresponding positioning address is
passed may drop momentarily.
1 : Near pass mode........................... Since positioning is not performed at the
address designated in the "positioning data",
the path merely passes near the designated
positioning address, but machine vibration
caused by the momentary output speed drop
can be suppressed.
Note) Refer to section "12.3.3 Near pass mode function" for details on the near
pass mode.
Pr.150 Setting for the restart allowable range when servo OFF to ON
Set the range that is used as a condition for enabling a restart when the servo
switches from OFF to ON. (This setting is disabled for the AD75TU of software
version "C" or earlier.)
0 : Restart not allowed ...................... A restart at servo OFF to ON is not allowed.
1 to 163840 : Restart allowed
(restart allowable
range) ......................... A restart is allowed (axis operation status is
during a stop) when the difference between
the last command position of the AD75 and
the current value at servo OFF to ON is less
than the set value.
Note) For a restart at servo OFF to ON, refer to section "12.4.5 Servo ON/OFF
function".
