# Jog of path option after block search (P-CHAN-00305)

P-CHAN-00305 | Jog of path option after block search for coupled axes
Description | This parameter can influence the starting motion of coupled axes (soft gantry) when automatic jog of path is activated. If the parameter is set to DEFAULT, the master and slave axes are moved decoupled to the forward position. When the SOFT_GANTRY_RESTART parameter is set, the process is started when the soft gantry coupling is active. In this case it is assumed that the master and slave axes are already in their correct positions (requested offset between master and slave correctly set or still available). The offset can be changed by the parameter SOFT_GANTRY_CHECK_RESTART.

If the parameter RESTART_GET_ACS_POS is set, the axis positions are also adopted before the approach block. This allows the system to react to shifts during block search and avoid an axis offset.

Parameter | block_search_restart_mode
Data type | STRING
Data range | DEFAULT: This setting is useful for machines where the master and slave axes move different workpieces or where a master-slave offset change is required in the jog of path motion since master and slave may be in any position at the time of starting.

SOFT_GANTRY_RESTART: This setting is useful for machines where the master and slave axes move a workpiece (mechanically linked) so that the required distance caused by the workpiece fixing remains constant.

SOFT_GANTRY_CHECK_OFFSET: This setting is only effective in combination with the SOFT_GANTRY_RESTART mode. If this mode is also activated, a check is made before starting whether the gantry axes moved within a defined value.

RESTART_GET_ACS_POS: This setting is useful for machines where the axes are moved during by influences outside of the CNC during block search. For example, axis couplings in the PLC, offsets, compensations, insertion of an NC program (jog of path) or manual shifting. The axis positions are adopted before the approach block so that there are no more axis offsets after approaching the contour.

Dimension | ----
Default value | DEFAULT
Remarks | In CNC Builds< V300, the data type is UNS32. The following values correspond to the strings: DEFAULT – 0 SOFT_GANTRY_RESTART – 1 SOFT_GANTRY_CHECK_OFFSET – 2 RESTART_GET_ACS_POS – 4

For example, if the SOFT_GANTRY_RESTART (0x01L) mode and also the SOFT_GANTRY_CHECK_OFFSET (0x02L) mode are activated, this is equivalent to a hex value of 0x03L.
