This example shows how to connect multiple Servo Drives.
Connect the EDM signal to the terminal EDM + P on the first Unit, and to the terminal EDM + on a Unit
from the second as shown in the following diagram when you use multiple Servo Drives.
When a G9SP-series safety controller is used, you can connect up to four 1S-series Servo Drives.
