[Da.6] Positioning address/movement amount
Set the address used as the target value for positioning control.
The setting range differs according to the value set in [Da.2] Control method.
■
Absolute (ABS) system and current value change
• Set the value (positioning address) with an absolute address (address from the OP) for the ABS system and current value
change.
■
Incremental (INC) system, fixed-feed 1, fixed-feed 2, fixed-feed 3, and fixed-feed 4
Set the value (movement amount) with a sign for the INC system.
• When the movement amount is positive: Moves in the positive direction (address increment)
• When the movement amount is negative: Moves in the negative direction (address decrement)
■
Speed-position switching control
• INC mode: Set the movement amount after the control method is switched from the speed control to the position control.
• ABS mode: Set the absolute address which is to be the target value after the control method is switched from the speed
control to the position control. (The unit is degree only.)
■
Position-speed switching control
• Set the movement amount in the position control (before switched to the speed control).
