Number of NC blocks at M/H code look ahead (P-CHAN-00274)

P-CHAN-00274

Number of NC blocks at M/H code look ahead

Description

This parameter increases the number of NC blocks for look ahead for M/H synchronisation types MEP_SVS and MET_SVS. By default the number of blocks is 50. Due to the additional required block buffer, the start-up parameter P-STUP-00071 and possibly P-STUP-00070 must be adapted for values > 70. The increased number of blocks causes an increased cycle time in the real-time part of CNC.
