3.16 Swiveling – CYCLE800 (SW 6.2 and higher)
Note about MD 18088:
If several channels are defined in the NCU, the number of
swivel data records is divided, taking
MD 28085: MM_LINK_TOA_UNIT into account.
Example:
MD 18088 MM_NUM_TOOL_CARRIER =4
Number of channels=2.
Two swivel data records are provided for each channel.
Note on MD 20150/MD 20152:
Equals 0, if there is no plane changeover + SWIVEL
(G17-G19).
Note on MD 20180/MD 20182:
The swivel data record with the Hirth tooth system is
described in the CYCLE800 rotary axes start-up screen.
Note about MD 22530:
If more than one swivel data record is declared per channel,
and if machine functions need to be activated on changeover
between swivel heads or tables, an M command can be
issued in the PLC program on switchover to another swivel
data record.
Example: Number of swivel data records in channel 1 =2
MD 22530: TOCARR_CHANGE_M_CODE = -800
Programming of swivel data record 1 (TCARR=1) à M801
Programming of swivel data record 2 (TCARR=2) à M802
By outputting special functions, the PLC can, for example,
limit or invert the spindle speed.
Note on MD 30455
This allows the axis to traverse for G90 with DC (shortest
path); see user cycle TOOLCARR.spf
