#UNSYNC [slave1 <,slave2> ...]
All the spindles are uncoupled if no parameter is defined.
Considerations for uncoupling
The synchronism is also canceled with M30 and RESET.
When canceling the synchronism, the master spindle stays in its current state and the slave
stops. The slave does not recover the M function prior to the synchronization, but it keeps
the synchronism gear until a new S function is programmed.
Variables associated with the synchronization movement
These variables are read/write (R/W) synchronous and are evaluated during execution.
They have generic names.
• Replace the "n" character with the channel number, maintaining the brackets. The first
channel is identified with the number 1, "0" is not a valid number.
• Replace the "Xn" character by the name, logic number or index in the channel of the axis.
Adjust the speed synchronism ratio
(V.)[n].A.GEARADJ.Xn
Read-only from the PRG, PLC and INT. The PLC reading comes in hundredths (x100)
Fine adjustment of the gear ratio during the synchronization itself. It is programmed as a
percentage of the original adjustment value.
Speed synchronization
(V.)[n].A.SYNCVELW.Xn
Read-only from the PRG, PLC e INT.
When the spindles are synchronized in speed, the slave spindle turns at the same speed
as the master spindle (taking the ratio into account). If the value defined in this variable is
exceeded, the SYNSPEED signal goes low; the movement is not stopped and no error
message is issued.
Its default value is that of machine parameter DSYNCVELW.
(V.)[n].A.SYNCVELOFF.Xn
Read-only from the PRG, PLC e INT.
Velocity offset of the slave spindle synchronization.
Parameter Meaning
slave Slave spindle to be synchronized.
#UNSYNC
All the spindles of the channel are uncoupled.
#UNSYNC [S1,S2]
Slave spindles S1 and S2 are uncoupled from the master spindle with which they were
synchronized.
