Detailed Description
2.6 Block search Type 5 SERUPRO
Spindle ramp-up
When the SERUPRO ASUB is started, the spindle is not accelerated to the speed specified
in the program because the SERUPRO ASUB is intended to move the new tool into the
correct position at the workpiece after the tool change.
A spindle rampup is performed with SERUPRO ASUB as follows:
• SERUPRO operation has finished completely.
• The user starts the SERUPRO ASUB via function block FC 9
• The start after M0 in the ASUB does not change the spindle status.
• SERUPRO ASUB automatically stops before the REPOS part program block.
• The user presses START.
• The spindle accelerates to the target block state if the spindle was not programmed
2.6.4 Selfacting SERUPRO
Selfacting SERUPRO
The channel-specific function "Self-acting SERUPRO" allows a SERUPRO sequence without
having to previously define a search target in a program of the associated SERUPRO
channels.
In addition, a special channel, the "serurpoMasterChan", can be defined for each "Self-acting
SERUPRO". A search target can be defined in this channel.
The "Selfacting SERUPRO" function supports the SERUPRO cross-channel block search.
