Speed-Position Switching Control (Abs Mode) - Mitsubishi Electric MELSEC iQ-R Series User Manual

Speed-position switching control (ABS mode)

In case of "speed-position switching control (ABS mode)" ("[Da.2] Control method" = 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".
