Parameterisable boundary conditions, specifying the mode of operation

Synchronization mode

Description

Define:

GeaInSyncMode

GEARINSYNCMODE_POSITIONBASED

In this mode of the universal flying saw, a profile dependent on the master position is generated to synchronize the slave axis to the master axis.

GEARINSYNCMODE_TIMEBASED

In this mode of the universal flying saw, a time-dependent motion profile is generated for synchronizing the slave axis to the master axis, which ensures compliance with all dynamic limit values of the slave axis. This mode is currently only available with coupling on velocity.

Bit masks for operation modes

GEARINSYNC_OPMASK_

Description

ROLLBACKLOCK

65536

0x0001 0000

Bit = 0: (default)

When the slave has achieved the synchronous phase, synchronous coupling of all the following master movements is maintained until the coupling is removed. This also applies if the master changes direction and moves backwards over the coupling position. (Further explanations)

Bit = 1:

Setting this bit activates the backstop, which causes the slave to stop when the master moves backwards beyond the coupling position after a motion reversal.   (Further explanations)

INSTANTSTOPONROLLBACK

131072

0x0002 0000

Bit = 0: (default)

On reaching the coupling position, the slave velocity is reduced smoothly following a 5th order polynomial. The polynomial is optimized to halt the slave as quickly as possible. (Further explanations)

Bit = 1:

In terms of the set value, the slave is halted within one NC tick of reaching the coupling position. The slave velocity is set to 0.0 and the position is maintained.
This abrupt stop can trigger the following error monitoring system! (Further explanations)

PREFERCONSTVELO

1048576

0x0010 0000

Bit = 0: (default)

Default setting

Bit = 1:

The system will try to use a phase with constant velocity, instead of just one 5th order polynomial. This can result in a combination of a 5th-order polynomial, a synchronous phase and another 5th-order polynomial (P5-P1-P5), (see further explanation). The maximum given acceleration and deceleration is used. To control and limit the jerk it is recommended to set MAXJERK in the bit mask.

IGNOREMASTERACC

2097152

0x0020 0000

Bit = 0: (default)

Default setting

Bit = 1:

When calculating the coupling, the acceleration of the master is ignored, i.e. set to zero. This causes the use of internal optimizations. At moderate acceleration, this specification leads to tolerable following errors. After the following error has been reduced, the relative position accuracy is independent of this setting.
