Signals For Synchronous Mode From Spindle - Siemens SINUMERIK 880 SW 6 Planning Manual

05.91
SPINDLE DISABLE
1 signal: The spindle is brought to a standstill according to the acceleration ramp.
0 signal: Spindle drive enable.
Notes:
• A message text can be allocated to any bit in DW K + 3.
• The previous set speed becomes effective when the spindle is enabled again. The
positioning operation is resumed if the positioning mode is active.
• Spindle disable is activated if at least one bit in DW K + 3 is set.
• The selection of the currently valid acceleration time constant is made with reference to
the actual gear stage and the mode:
– In control or oscillation mode MD 419* to 426* "Acceleration time constant without
position control" are used.
– In synchronous or positioning mode when selected by NC or PLC, MD 478* to 485*
"Acceleration time constant with position control" are used.
– In positioning mode when selected by command channel the acceleration time
constant from the user DB is used.

Signals for synchronous mode from spindle

NEW K CALCULATED
Ü
1 signal: The new speed ratio K
been calculated without error.
0 signal: New speed ratio not calculated.
Notes:
• The new K must be activated by setting the ACTIVATE NEW K
Ü
corresponding setting data bit.
• The NEW K CALCULATED signal is automatically reset when the new K
Ü
DEFINED ANGULAR OFFSET REACHED
1 signal: The programmed angular offset between the following spindle and its leading
spindle has been reached.
0 signal: No defined angular offset between the leading and following spindles.
Notes:
• The angular offset is specified by the G201 command.
• Programming an angular offset is optional.
• The signal is reset when the G201 command is activated.
• The signal is of significance only to the following spindle in synchronous mode.
