• An attempt has been made to select the GWPS programming for a spindle that has
already been assigned to another tool by TMON, GWPSON, CLGON or activation of the
tool length compensation.
• 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 was specified.
On deselecting grinding wheel surface speed 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.
• Selection refers to an invalid spindle number.
- Correction block is reorganized.
- Interface signals are set.
- Alarm display.
• Check GWPSON and GWPSOF command.
• Check tool compensation data:
$TC_DP1 : 400 - 499;
$TC_TGP1: Spindle number.
Clear alarm with NC START or RESET key and continue the program.

%2 = Block number, label
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.
- Correction block is reorganized.
- Interface signals are set.
- Alarm display.
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.
Clear alarm with NC START or RESET key and continue the program.
