Address settings (SW1)
Set the address selector of the Accurax G5 Servo Driver to the required
node address by using the X1 (right) and X10 (left) rotary switches.
The setting range for the node address setting rotary switch is 1 to 31. The
actual station address used on the network will be the sum of the rotary
switch setting and the offset value of 40h. These node addresses
correspond to axis numbers 0 (node address = 1) to 15 (node address = 16).
Note
The node address set by the rotary switch is read only once when
the control power is turned on. Any changes made by the rotary
switches after the power-on are not reflected to the Controller.
Such changes become effective only after the subsequent power-
on following to a power-off. Do not change the rotary switch setting
after the power-on.
Note
The settable range for a node address is between 1 and 31. The
node address used over the network is the value obtained by add-
ing the offset 40h to the rotary switch set value. If any value over or
under the range is set, the Node address setting error (Err82.0)
occurs.
