Sync Port

The Sync port is a bi-directional high speed proprietary interface that lets you transmit encoder signals between drives. The drive contains two Sync ports, labeled A and B. To avoid signal contention, all Sync ports default to the input state during reset and immediately after power is applied to the drive.

This is typically used for multi-axis PSO applications where one or two drives send their encoder signals to a main drive that has the PSO logic and PSO output signal.

Refer to the DriveEncoderOutputConfigureInput() function for more information on how to transmit encoder signals from a SYNC port.

You can only echo incremental square wave primary encoder inputs or, with the -MX2 or -MX3 option, incremental sine wave primary encoder inputs. You cannot use the absolute encoder interface when you echo incremental signals.

Function

Description

DriveEncoderOutputConfigureDivider(),

DriveEncoderOutputConfigureInput(),

DriveEncoderOutputOn(),

DriveEncoderOutputOff()

Configure each Sync port as an input or an output

PsoDistanceConfigureInputs()

Let the PSO track the SYNC A or SYNC B port.

PsoWindowConfigureInput()

The Sync port uses low-voltage differential signaling (LVDS) and standard USB 3.0 type A (cross over) cables.
