Speed-position switching control (INC mode)
In the speed-position switching control (INC mode) ([Da.2] Control method = Forward run speed-position, Reverse run speed-
position), pulses are output continuously at the speed set in [Da.8] Command speed in the axis direction set to the positioning
data. When Speed-position switching signal is input, the position control for the movement amount set in [Da.6] Positioning
address/movement amount is performed.
The speed-position switching control (INC mode) has two control types including Forward run speed-position performed in the
forward run direction and Reverse run speed-position performed in the reverse run direction.
The speed-position switching control (INC mode) can be set to [Pr.150] Speed-position function selection in the detailed
parameter 1.
If a value other than 0 and 2 is set, the control is performed in the INC mode with the setting value regarded as 0.
For details on the settings, refer to the following.

Switching from the speed control to position control
• Select a method to switch from the speed control to position control setting the value of [Cd.45] Speed-position switching
device selection.
• To switch the speed control to the position control, [Cd.24] Speed-position switching enable flag must be turned on and
positioning data must be set. (When [Cd.24] Speed-position switching enable flag is turned on after Speed-position
switching signal is turned on, the speed control is not switched to the position control. The speed control is switched to the
position control when Speed-position switching signal is turned on again. If [Cd.24] Speed-position switching enable flag
and External command signal are turned on at the start of the control, only the position control is performed.)
