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".
Forward run: speed/position, Reverse run: speed/position), the pulses of the speed set

If the set value is other than 0 and 2, it is regarded as 0 and operation is performed in the INC
mode.
