Gwps In All Operating Modes - Siemens SINUMERIK Series Function Manual

17.5.3

GWPS in all operating modes

General information
This function allows the constant grinding wheel peripheral speed (GWPS) function to be
selected for a spindle immediately after POWER ON and to ensure that it remains active
after an operating mode changeover, RESET or part program end.
The function is activated via the machine data:
MD35032 $MA_SPIND_FUNC_RESET_MODE (parameterization of the GWPS function)
GWPS after POWER ON
A grinding-specific tool is defined via the following machine data:
MD20110 $MC_RESET_MODE_MASK
MD20120 $MC_TOOL_RESET_VALUE
MD20130 $MC_CUTTING_EDGE_RESET_VALUE
Note
MD35032 $MA_SPIND_FUNC_RESET_MODE
If the above machine data is set and a grinding-specific tool (tool type 400 to 499, MD20110,
MD20120, MD20130) is used with reference to a valid spindle (parameter $TC_TPG1), then
GWPS is activated for that spindle.
GWPS is deselected for all other spindles in this channel.
GWPS after RESET/part program end
After a RESET/part program end, GWPS remains active for all spindles for which it was
already selected.
Note
MD35032 $MA_SPIND_FUNC_RESET_MODE
If the machine data above is set and GWPS is active on RESET or part program end, then
GWPS remains active for this spindle.
If machine data MD35032 $MA_SPIND_FUNC_RESET_MODE is not set and GWPS is
active on RESET or part program end, then GWPS is deactivated for this spindle.
GWPS is deselected for all other spindles in this channel.
It can be determined as to whether the spindle continues to rotate with the actual speed after
RESET using the following machine data:
MD35040 $MA_SPIND_ACTIVE_AFTER_RESET
