I added a Servo Drive to the EtherCAT node address network configuration in the Sysmac Studio. Then, in the I/O Map, I assigned drive variables to the I/O ports. When I added an axis setting and assigned a target node, the assignments in the I/O Map were grayed out. What should I do to access the Servo Drive?
The I/O Map entries become disabled as soon as you assign a Servo Drive to an axis. To access the Servo Drive that you assigned to an axis, use the Axis Variable (a system-defined variable).
