Synchronous Spindles (S3)
Programming of synchronous spindle couplings
● Coupling type
DV (Desired Values): Setpoint coupling between FS and LS
AV (Actual Values): Act.-val. coupl. between FS and LS
VV (Velocity Values): Speed coupling between FS and LS
If no coupling type is specified, then the currently selected type continues to apply.
Note
The coupling type may only be changed when synchronous operation is deactivated!
Examples
COUPDEF (SPI(2), SPI(1), 1.0, 1.0, "FINE", "DV")
COUPDEF (S2, S1, 1.0, 4.0)
COUPDEF (S2, SPI(1), 1.0)
Default settings
The following default settings apply to user-defined couplings:
● Ü
● Ü
● Block change response = IPOSTOP (block change enabled with setpoint synchronism)
● Type of coupling = DV (setpoint coupling)
Delete couplings
Language instruction "COUPDEL" is used to delete user-defined couplings.
COUPDEL (FS, LS)
Note
COUPDEL impacts on an active coupling, deactivates it and deletes the coupling data. Alarm
16797 is therefore meaningless.
The following spindle adopts the last speed. This corresponds to the behavior associated
with COUPOF(FS, LS).
