Setting An Address For Each Servo Amplifier; Reading The Value Of Rotary Switch; Reading The Value Of Sii Area - Panasonic GM1 Series User Manual

9.1 Setting an Address for Each Servo Amplifier

9.1 Setting an Address for Each Servo Amplifier
The following are the address setting methods prescribed by EtherCAT.
● Reading the Value of Rotary Switch
● Reading the Value of SII Area

9.1.1 Reading the Value of Rotary Switch

Addresses are set using the value of the rotary switch on each servo amplifier.
This setting method is explained using MINAS-A5B as an example.
By setting the Pr7.41 parameter to 0, the value of the rotary switch on the front panel can be
used as an address.
In this case, the value of the rotary switch and the value of Pr7.40 are combined and used as
an address.

9.1.2 Reading the Value of SII Area

Addresses are set using the value of the SII area (0004h) in each servo amplifier.
This setting method is explained using MINAS-A5B as an example.
By setting the Pr7.41 parameter to 1, the value of the SII area (0004h) can be used as an
address.
The value of the SII area (0004h) can be set using the EtherCAT slave device object of GM
Programmer.
The following figure illustrates the correlation between the settings in GM Programmer and the
wiring of each servo amplifier when addresses are set using the value of the SII area.
