Selection/deselection and programming of GWPS, system variable

Part program commands
The GWPS is selected and deselected with the following part program commands:
Command
GWPSON
Grinding wheel peripheral speed ON
GWPSOF
Grinding wheel peripheral speed OFF
GWPSON
Grinding wheel peripheral speed ON (T no.)
GWPSOF
Grinding wheel peripheral speed OFF (T no.)
[spindle number] = value

Note
Parameter $TC_TPG1 assigns a spindle to the tool. Every following S value for this spindle
is interpreted as a grinding wheel peripheral speed when GWPS is active (see above).
If GWPS is to be selected with a new tool for a spindle for which the GWPS function is
already active, the active function must be deselected first with
given out).
GWPS can be active simultaneously for several spindles, each with a different grinding tool,
in the same channel.
Selection of GWPS with
compensation or of the geometry and speed monitoring functions. When GWPS is
deselected, the last speed to be calculated remains valid as the setpoint.
$P_GWPS[spindle number]
This system variable can be used to query from the sub-program whether the GWPS is
active for a specific spindle.
