• SPOS and M19
The block change is carried out if all functions programmed in the block have reached their endofblock
criterion (e.g. all auxiliary functions acknowledged by the PLC, all axes have reached their end points) and the
spindle has completed its positioning motion.
• SPOSA
The program moves to the next block if all the functions (except for spindle) programmed in the current block
have reached their end-of-block criterion. If SPOSA is the only entry in the block, block change is performed
immediately. The spindle positioning operation may be programmed over several blocks (see WAITS).
Coordination
A coordination of the sequence of motions can be achieved with:
•PLC
• MD configuration
• Programming in the part program
PLC
If the NC/PLC interface signal:
DB31, ... DBX83.5 (spindle in the setpoint range)
is not available, then the channel-specific NC/PLC interface signal:
DB21, ... DBX 6.1 (read-in inhibit)
can be set in order to wait for a spindle to reach a certain position.
MD configuration
Setting:
MD35500 $MA_SPIND_ON_SPEED_AT_IPO_START = 1
is used to perform path interpolation taking the tolerance:
MD35150 $MA_SPIND_DES_VELO_TOL
into account only if the spindle has rotated up to the preselected speed.
The setting
MD35500 $MA_SPIND_ON_SPEED_AT_IPO_START = 2
is used to stop traveling path axes before the start of machining at the last G0.
Machining continues:
• On the next traversing command
• If the spindle speed is reached
• When MD35510 $MA_SPIND_STOPPED_AT_IPO_START = 1
(path feed enable, if spindle stationary)
