link the multiplication. The product is added to the total compensation value of the
compensation axis.
– Machine data:
MD32710 $MA_CEC_ENABLE[<AXi>] (enable sag compensation)
enables the sum of all compensation relationships for machine axis <AXi>.
– With the setting data:
SD41300 $SN_CEC_TABLE_ENABLE[<t>] (pre-assignment for the compensation
table)
evaluation of the compensation table [<t>] is enabled.
It is thus possible e.g. to alter the compensation relationships either from the part
program or from the PLC user program (e.g. switching over the tables), depending on
the machining requirements.
