2: Use the value set in "[Pr.29] Deceleration time 2".
3: Use the value set in "[Pr.30] Deceleration time 3".
[Da.6] Positioning address/movement amount
Set the address to be used as the target value for positioning control.
The setting value range differs according to the "[Da.2] Control method".

Absolute (ABS) system, current value changing
• The setting value (positioning address) for the ABS system and current value changing is set with an absolute address
(address from home position).

• The setting value (movement amount) for the INC system is set as a movement amount with sign.
When movement amount is positive: Moves in the positive direction (address increment direction)
