4.1 Defining auxiliary functions
Auxiliary Function Output to PLC (H2)
4-2 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
• The gear stage last programmed is to be output after block search. For this purpose, the
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
• Auxiliary functions M3, M4, M5, M70 and M1=3, M1=4, M1=5, M1=70 (auxiliary function
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
• The auxiliary functions for gear change M40 to M45 and M1=40 to M1=45 (auxiliary
function group 9) are to have the following output behavior:
– Output duration one OB1 cycle (normal acknowledgment)
– Output prior to motion
Spindle 2
• Only one M function for directional reversal may be programmed in one block. The
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
• 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
values (auxiliary function group 11) are to have the following output behavior:
– Output duration one OB40 cycle (quick acknowledgment)
– Output prior to motion
Cooling water
• It is not permissible to switch the cooling water on and off in one part program block. After
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
• Auxiliary functions M50, M51 (auxiliary function group 12) and M52, M53 (auxiliary
function group 13) are to have the following output behavior:
– Output duration one OB1 cycle (normal acknowledgment)
– Output prior to motion
