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 additionally required block buffer, the parameter P-CHAN-00653 and possibly P-CHAN-00650 (or alternatively start-up parameter P-STUP-00071 and possibly P-STUP-00070must be adapted for values > 70.

The increased number of blocks causes an increased cycle time in the real-time part of CNC.

Remarks

Configuration example:

• Channel parameter list:

m_h_pre_outp_nbr_block     100     #100 blocks M code look ahead

# P-CHAN-00653 - Large Look-Ahead buffer

configuration.interpolator.parameter  100

# P-CHAN-00655 – Activate customer-specific
# setting for Look-Ahead

configuration.interpolator.fct_enable[0]  FCT_LOOK_AHEAD_CUSTOM

• Alternatively - in the start-up parameter list, modify instead of P-CHAN-00653 and P-CHAN-00650

configuration.channel[0].interpolator.parameter  100
configuration.channel[0].interpolator.function   FCT_LOOK_AHEAD_CUSTOM
