FANUC Series 30i/31i-MODEL A

Flexible synchronization control

5) Issuing G28, G30, G30.1 or G53 during synchronization control results

in the PS010 (IMPROPER G CODE) alarm being issued. Before

issuing G28, G30, G30.1 or G53, cancel synchronization control.

6) The parameters (Nos. 5660 to 5667, 5670 to 5677, 5680 to 5687, and

5690 to 5693) can be set in a part program that uses a programmable

parameter input (G10).

However, even if a flexible synchronization control mode changes the

parameter of the group of turning on, the parameter does not become

effective at once. It is necessary to turn off a flexible synchronization

control mode once to make the changed parameter effective, and turn

on the mode again.

7) The display of the slave axis position may or may not be updated by

synchronization pulses as follows:

♦ The machine position display is updated.

(The display may appear not to be in synchronization, because

update is based on post-acceleration/-deceleration a travel distance.)

♦ Neither the absolute position display nor the relative position display

is updated.

The absolute position display and the relative position display of the

slave axis are updated by adding a synchronization-based travel

distance when synchronization is canceled.

However, when the parameter of not updating the machine coordinates

of the group is set(Parameter No.5668#0-#3 is 1), the update operation

of the above-mentioned absolute coordinate and the relative coordinate

is not done.

8) When the flexible synchronization mode is turned from off to on during

an automatic operation, the PS5242 (ILLEGAL AXIS NUMBER)

alarm is issued if the specified master or slave axis number is incorrect.

9) When the flexible synchronization mode is turned from off to on during

an automatic operation, the PS5243 (DATA OUTRANGE) alarm is

issued if the specified gear ratio is incorrect.

10) When the flexible synchronization mode is turned from off to on or on

to off during an automatic operation, the PS5244 (TOO MANY DI ON)

alarm is issued if the mode signal does not become on or off after an M

code is executed.

11) A synchronous group which makes the PMC axis a master axis must

turn on EAXn signal (G0136) of the PMC axis control previously

before turning on the flexible synchronization mode.

12) A synchronous group which makes the PMC axis a master axis must

turn on the flexible synchronization mode by M code under automatic

operation.

When the flexible synchronization mode is turned on excluding

automatic operation, the alarm of PS5245 (OTHER AXIS ARE

COMMANDED) is issued.

13) AI contour control I or AI contour control II is automatically turned off

while the mode of a synchronous group which makes the PMC axis a

master axis turns on.
