Overview of Alarms
• An attempt has been made to select a tool which has not been defined.
• An attempt has been made to select an edge (implicitely) which has not been defined
(implicit selection: D1 of a tool, if no tool has been specified.)
• Selection does not refer to a grinding-specific tool (400-499).
• An attempt has been made to select GWPS for the active tool, although the TLC is not
switched on.
• Selection refers to an invalid spindle number.
• A grinding wheel radius equal to zero has been specified.
On deselecting GWPS programming with GWPSOFF, one of the following errors
occurred:
• Deselection does not refer to a grinding-specific tool (400-499).
• An attempt has been made to deselect GWPS for the active tool, although the tool
length compensation has not been activated.
• Deselection refers to an invalid spindle number.
Reactions: - Correction block is reorganized.
- Interface signals are set.
- Alarm display.
Remedy: • Check GWPSON and GWPSOF command.
• Check tool compensation data:
$TC_DP1 : 400 - 499;
$TC_TGP1: Spindle number.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:

Channel %1 block %2 incorrect programming of GWPS
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: When selecting GWPS (constant grinding wheel peripheral speed) with GWPSON or pro-
gramming the GWPS with "S[spindle number] = value" one of the following errors has
occurred:
Invalid spindle number.
Invalid parameter number for radius calculation in $TC_TPG9.
The following values are valid:
3 for $TC_DP3 (length 1)
4 for $TC_DP4 (length 2)
5 for $TC_DP5 (length 3)
6 for $TC_DP6 (radius)
Invalid angle in $TC_TPG8.
The following values are valid: -90 <= $TC_TPG8 < +90.
A grinding wheel radius equal to zero was specified.
Reactions: - Correction block is reorganized.
- Interface signals are set.
- Alarm display.
Remedy: Check tool compensation data.
• $TC_DP1 : 400 - 499.
• $TC_TPG1: Spindle number.
• $TC_TPG8: Inclination angle for slope grinding wheel.
• $TC_TPG9: Compensation parameters for radius computation, e.g. 3 for $TC_GP3.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
