Speed-Position Switching Control (Inc Mode) - Mitsubishi Electric MELSEC iQ-F Series FX5 User Manual

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 implemented.
The speed-position switching control (INC mode) has two control types including Forward run speed-position implemented in
the forward run direction and Reverse run speed-position implemented in the reverse run direction.
Set the speed-position switching control (INC mode) selection using "[Pr.150] Speed-position function selection".
Setting item
[Pr.150] Speed-position function
selection
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.

• 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, speed control→position control switching is not implemented. The speed control is switched
to the position control when the speed-position switching signal is turned from OFF→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
implemented.)
