S3: Synchronous spindle
19.2 Programming
COARSE: Block change in response to "Coarse synchronism"
IPOSTOP: Block change for IPOSTOP (i.e. after setpoint-end synchronism)
The block change response is specified as a character string (i.e. with quotation marks).
The block change response can be specified simply by writing the letters in bold print. The
remaining letters can be entered to improve legibility of the part program but they are not
otherwise significant.
If no block change response is specified, then the currently selected response continues to
apply.
With the programmable synchronism test markers WAITC, the replacement with new blocks is
delayed until the parameterized synchronism is reached.
● Coupling type
DV (Desired Values): Setpoint coupling between FS and LS
AV (Actual Values): Actual value coupling 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 command "COUPDEL" is used to delete user-defined couplings.
