A-6-1 Relationship between Unit Versions and Sysmac Studio Versions
A-6 Version Information
This section describes the relationship between the unit versions of 1S-series Servo Drives and the
Sysmac Studio versions, and the functions that were added or changed for each unit version.
This section also describes how the unit versions of 1S-series Servo Drives correspond to Sysmac Stu-
dio versions.
The following table gives the relationship between unit versions of 1S-series Servo Drives and the cor-
responding Sysmac Studio versions.
The operation specifications depending on combinations of unit versions of 1S-series Servo Drives and
Sysmac Studio versions are given in this section.
Using a Lower Version of the Sysmac Studio
When you use the Sysmac Studio that does not correspond to the unit version of Servo Drive, you
cannot select the unit version of your Servo Drive from the device list of Sysmac Studio. When you
use the Sysmac Studio without its update, select from the displayed unit versions.
Example: Unit version 1.2 of Servo Drive
Sysmac Studio version 1.17
Sysmac Studio version 1.17 corresponds to up to the unit version 1.0 of the Servo Drive.
Therefore, you select the unit version 1.0. In this case, the Servo Drive operates as fol-
lows.
• The Servo Drive can use only functions of Sysmac Studio that are supported by the unit
version 1.0.
• It is impossible to set the servo parameters that were added in the unit version 1.2.
Therefore, the Servo Drive operates with the present set values.
• When you execute Initialize drive by Sysmac Studio, all servo parameters of the unit
version 1.2 are restored to the default values.
