2. Location Adjustment of Synchro Axes Sliders

Align the synchro axes sliders. (Physical parallel adjustment)

(1) Adjust the relative locations between the sliders of the master and slave axes and connect

them while the axes are not connected to the controller via cables (controller main power

OFF).

(2) If location adjustment cannot be made while the axes are not connected to the controller via

cables (such as with the brake), follow the steps below.

① Disconnect the sliders temporarily and connect the axes to the controller via cables.

② Record the current values of the “each-axis parameter No. 65 synchro other axis No.” for

the master and slave axes. (Record them to return to their original values in a later

process.)

③ To cancel the synchro function temporarily, input 0 to the “each-axis parameter No. 65

synchro other axis No.” for both the master and slave axes, and execute the data transfer

to the controller, Flash ROM writing and controller restart (software reset) in this order.

④ Execute an absolute reset (standard procedure) for each of the master and slave axes as

a single axis.

⑤ Adjust the relative locations of the sliders by jog operation, etc., and connect them.

⑥ To activate the synchro function again, input the values recorded in ② above to the

“each-axis parameter No. 65 synchro other axis No.” for the master and slave axes, and

execute the data transfer to the controller, Flash ROM writing and controller restart

(software reset) in this order.

3. Special Procedure Absolute Reset

In the case of “each-axis parameter No. 38 encoder ABS/INC type”: master axis = 1 and slave

axis = 1:

(1) Record the current value of the “each-axis parameter No. 83 ABS synchro slave axis

coordinate initialization cancel” for the slave axis. (Record it to return to the original value in a

later process.)

Mode Transition:

(2) Input 0 for the “each-axis parameter No. 83 ABS synchro slave axis coordinate initialization

cancel” for the slave axis.

Input 0 with the 10 keys and press the return key.
