Rotary switch

The rotary switch (SW1) sets the MECHATROLINK-II address that identifies
the GRT1-ML2 in the MECHATROLINK-II network. The settings range is
from 0 hex to F hex.
To set the MECHATROLINK-II address of the GRT1-ML2, do these steps:
1. Turn off the Unit power supply of the GRT1-ML2.
The address of the GRT1-ML2 is read only at power on. Setting
the new address when the power is on has no effect.
2. To set the address of the unit, set communication dipswitch 1 and the
rotary switch as given in the table below.

network. If two or more units have the same MECHATROLINK-II
address, they cannot be initialized properly.

of these steps:
