Revision: A4
3.6.3
Sync Output Connector Group
Output Source
This determines which signal is sent out the Sync Output connector on the drive. If Motor Encoder (default) is selected, the encoder signals
from the motor that the drive is controlling will be sent out the 15-pin Analog/Sync Output connector (J5). If Drive Encoder Input is selected,
then the signals coming in the drives 9-pin Sync Input connector on the drive will be sent out the Analog/Sync. Output connector. When Virtual
Master is selected the virtual master signal generated by the drive will be sent out the Analog/Sync. Output connector.
3.6.4
Dual Loop Encoder Ration
Motor Encoder
This parameter is the numerator in the ratio used to define the mechanical ratio between the Motor Encoder and the Position Feedback
Encoder. This parameter is only used when Dual Loop Control Mode is enabled, and must be set correctly to achieve the correct target
velocity.
Position Encoder
This parameter is the denominator in the ratio used to define the mechanical ratio between the Motor Encoder and the Position Feedback
Encoder. This parameter is only used when Dual Loop Control Mode is enabled, and must be set correctly to achieve the correct target
velocity.
3.7
Master Units View
Master Units View provides the setup parameters for use with synchronized motion. This setup window determines how the encoder signals
are interpreted and establishes the scaling for all master units (master distance, master velocity, etc.).

Encoder Setup Group
Master Source
Master Source (MasterAxis.Source) indicates the source of the master encoder input.
Select Custom Variable, the Custom Variable text box will became available to enter a parameter. The custom variable can be entered two
ways: by just typing any parameter into the text box using the program format for the variable, or click the Popup Variables button and the
Select Variables from Tree window will open. Select the variable and drag it over to the Custom Variable text box.
Select Sync Encoder Input to use the Sync Input connector (J10) on the Epsilon EP drive.
Select Virtual Master.Counts to use the Virtual Master as the Master Source.
Custom Variable
The Custom Variable (MasterAxis.CustomSourceVariable) text box is only available once the user has selected Custom Variable from the
Master Source list box. This field is used to define what parameter will be used as the Master Source. The Custom Variable can be entered two
ways: by just typing any parameter using the program format for the variable, or click the Popup Variables button and the Select Variables from
Tree window will open. Select the variable and drag it over to the Custom Variable text box.
