10-2-4 Preparing the Linear Motor for Operation

At the Servo Drive, you must perform the following three types of basic settings appropriate to the
Linear Motor and external encoder you connect to it.
• Setting the Linear Motor and external encoder specifications
• Adjusting the current loop gain
• Setting the magnetic pole detection data
To set the data obtained as above, have the Sysmac Studio or CX-Drive ready. For details on operating
these tools, refer to 10-3 Linear Motor Setup on page 10-13.
The details of the objects that must be set for each of the above basic settings are described below.
Setting the Linear Motor and External Encoder Specifications
Check the specifications of the Linear Motor you connect to the Servo Drive and set the necessary
objects according to the following table.
