9 MAJOR POSITIONING CONTROL
9.2.17 Speed-position switching control (ABS mode)
In case of "speed-position switching control (ABS mode)" (" Da.2 Control system" =
Forward run: speed/position, Reverse run: speed/position), the pulses of the speed set
in "
Da.8
Command speed" are kept output in the axial direction set to the positioning
data. When the "speed-position switching signal" is input, position control to the
address set in "
Da.6 Positioning address/movement amount" is exercised.
"Speed-position switching control (ABS mode)" is available in two different types:
"forward run: speed/position" which starts the axis in the forward run direction and
"reverse run: speed/position" which starts the axis in the reverse run direction.
"Speed-position switching control (ABS mode)" is valid only when "
Pr.1 Unit setting"
is "2: degree".
