Synchronous operation

When synchronous operation is active, spindle commanding for coupled spindle axes is mapped by the master spindle onto the slave spindles, i.e. implicit parallel command of slave axes takes place.

Coupling specifications for spindle axes are defined analogously to those of path axes [PROG//Synchronous operation].

Coupled spindles are commanded in parallel. Setpoints are not coupled synchronously with cycles.

There is no need for the separate commands for slave spindles for speed or positioning commands otherwise required in the NC program or for the technology functions and their acknowledgements.

Example of a machine structure for synchronous operation with spindles

Characteristics:

2-axis systems with one common X axis

Master system: X, Y1, Z1,C1, S1

Slave system: Y2, Z2, C2, S2

Default assignment in channel parameters

In the channel parameters [CHAN//Synchronous mode settings] spindles can be assigned defaults for synchronous mode as coupling pairs in coupling group 0:

Parameter

P-CHAN-00037	Logical no. of master axis
P-CHAN-00038	Logical no. of slave axis
P-CHAN-00061	Mode (for spindle axis: 1)

Programing Example

Axis coupling defaults:

koppelgruppe[0].paar[i].log_achs_nr_slave log. no. slave axis

koppelgruppe[0].paar[i].log_achs_nr_master log. no. master axis

koppelgruppe[0].paar[i].mode Spindle axis (1)

i: coupling pair

koppelgruppe[0].paar[0].log_achs_nr_slave 6

koppelgruppe[0].paar[0].log_achs_nr_master 1

koppelgruppe[0].paar[0].mode

Programming

Synchronous mode of spindles is programmed in the NC program by means of the following NC commands [PROG//Selecting and deselecting axis couplings]:

Definition of a coupling specification:

#SET AX LINK[…]

Select synchronous mode:

#ENABLE AX LINK[…]

Deselect synchronous mode:

#DISABLE AX LINK

The default assignments in the channel parameters can be selected in the NC program

#ENABLE AX LINK[0]

Notice

Synchronous mode for spindles cannot be used in combination with rotary functions.
