4.1 Defining auxiliary functions
• The gear stage last programmed is to be output after block search. For this purpose, the
• Auxiliary functions M3, M4, M5, M70 and M1=3, M1=4, M1=5, M1=70 (auxiliary function
• The auxiliary functions for gear change M40 to M45 and M1=40 to M1=45 (auxiliary
Spindle 2
• Only one M function for directional reversal may be programmed in one block. The
• All S2 values are assigned to auxiliary function group 11.
• Auxiliary functions M2=3, M2=4, M2=5, M2=70 (auxiliary function group 10) and the S2
Cooling water
• It is not permissible to switch the cooling water on and off in one part program block. After
• Auxiliary functions M50, M51 (auxiliary function group 12) and M52, M53 (auxiliary
4-2
following auxiliary functions are assigned to auxiliary function group 9:
– M40, M41, M42, M43, M44, M45
– M1=40, M1=41, M1=42, M1=43, M1=44, M1=45
group 2) and the S and S1 values (auxiliary function group 3) are to have the following
output behavior:
– Output duration one OB40 cycle (quick acknowledgment)
– Output prior to motion
function group 9) are to have the following output behavior:
– Output duration one OB1 cycle (normal acknowledgment)
– Output prior to motion
direction of rotation last programmed is to be output after block search. For this purpose,
the following auxiliary functions are assigned to auxiliary function group 10:
– M2=3, M2=4, M2=5, M2=70
values (auxiliary function group 11) are to have the following output behavior:
– Output duration one OB40 cycle (quick acknowledgment)
– Output prior to motion
a block search, the cooling water will be switched on or off. For this purpose, the following
auxiliary functions are assigned, for example, to auxiliary function group 12 or 13:
– 12. auxiliary function group: M50, M51
– 13. auxiliary function group: M52, M53
function group 13) are to have the following output behavior:
– Output duration one OB1 cycle (normal acknowledgment)
– Output prior to motion
Auxiliary Function Output to PLC (H2)
