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

Speed-position switching control (ABS mode)

In the speed-position switching control (ABS 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 to the address set in [Da.6] Positioning
address/movement amount is implemented.
The speed-position switching control (ABS 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.
The speed-position switching control (ABS mode) is enabled only when 2: degree is set to [Pr.1] Unit setting.
