公式トラブルシューティング手順
Parameters: %1 = Channel number %2 = Block number, label Definitions: On selecting GWPS programming (constant grinding wheel surface speed) with GWPSON, one of the following errors occurred: - 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. - An attempt has been made to select a tool which has not been defined. - An attempt has been made to select an edge (impli citely) 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 th e active tool, although the tool length compensation has not been activated. - Deselection refers to an invalid spindle number. Reaction: 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 Continuation: Clear alarm with NC ST ART or RESET key and continue the program. Diagnostics Manual (DAsl), 03/2009
