14.10 Interpolated Position Mode
14-36
Interpolation Time Period (60C2 hex) (Object Shared by
Mode 1 and Mode 2)
This object defines the interpolated position reference period for Interpolation Position Mode.
If DC Sync0 Mode is selected, the interpolation time period is automatically stored as the
Sync0 Cycle Time. If DC Free-Run Mode is selected, set the object manually.
Interpolation time = (Interpolation time period (60C2 hex: 01))

Note: You can change this object only under the following conditions.
•
When DC Sync0 Mode Is Selected:
EtherCAT (CoE) is in the Switch ON Disable state.
•
When DC Free-run Mode Is Selected:
EtherCAT (CoE) is in the Switch ON Disable state.
Or, EtherCAT (CoE) is in Interpolated Position Mode and
enable interpolation
equals 0.
