SoftMotion Drive Interface (SDI) Plug-in for Parker E Series EtherCAT stepper drives. Please read all release notes and known issues before using.
Allows NI SoftMotion VI's and examples to control Parker E Series EtherCAT stepper drives. Single and multiple drives supported. Multiple 3rd party EtherCAT drives on the same EtherCAT network supported.
This package requires the following installed software:
-NI LabVIEW 2016 or later
-NI Real-Time Module 16.0 or later
-NI RIO 16.0 or later (included in CompactRIO or Industrial Controller 16.0 or later)
-NI SoftMotion 2016 or later
-NI Industrial Communications for EtherCAT 16.0 or later
This package also requires VI Package Manager 2016 or later.
VI Package Manager must be run with administrator privileges to ensure this package is installed correctly.
- Minimum Parker E Series Drive Software Version: 1.00
- Plug-in supports 1, 2, 4, and 5 millisecond Scan Engine Periods on the RT Target
- Cyclic Synchronous Position Mode supported
- Profile Velocity Mode not supported
- Profile Torque Mode not supported
- Find Reference types supported:
Find Reference Move - Forward Limit
Find Reference Move - Reverse Limit
Find Reference Move - Index
Find Reference Move - Home*
Find Reference Move - Absolute
Reference Move Notes:
- After a SoftMotion Find Reference routine with Parker E Series EtherCAT drives, the position resets to 0 after any reference move. It is recommended to perform a Find Reference move before calling SoftMotion Reset Position.
- Only DS402 Home Modes 24 and 28 are supported when performing a SoftMotion Find Home Reference Move. If a different combination of move parameters should command another homing mode, this will be overwritten with the following settings depending on starting direction:
- Move Mode 24: Start Search Forward = TRUE, Stop on Forward Edge = FALSE, Approach Forward = TRUE
- Move Mode 28: Start Search Forward = FALSE, Stop on Forward Edge = TRUE, Approach Forward = FALSE
- Digital I/O Support:
Parker E Series drives have 10 digital inputs and 6 digital outputs available on the I/O connector. The SDI plug-in will write the necessary objects to reassign the digital I/O lines as seen below:
Parker Limit+: Forward Limit Switch Parker Out1: SoftMotion DO0
Parker Limit-: Reverse Limit Switch Parker Out2: SoftMotion DO1
Parker Origin: Home Switch Parker Out3: SoftMotion DO2
Parker In1: SoftMotion DI0 / Touch Probe Input Parker Out4: SoftMotion DO3
Parker In2: SoftMotion DI1 Parker Out5: SoftMotion DO4
Parker In3: SoftMotion DI2 Parker Out6: SoftMotion DO5
Parker In4: SoftMotion DI3
Parker In5: SoftMotion DI4
Parker In6: SoftMotion DI5
Parker In7: SoftMotion DI6
Touch Probe Note: Touch Probe 1 is assigned to Parker In1 by writing SDO 0x60D0 in the Initialize.vi of the plug-in. The drive also supports using In2, Origin, or Z-index for the touch probe source.
- Unit Scaling:
By default, the SoftMotion axes are configured without unit scaling. This means moves will be commanded in units of encoder counts. Right click on the SoftMotion Axis and use the Encoder tab to change the position scaling by setting the number of encoder counts per desired unit.
- EtherCAT Slave Configuration:
EtherCAT Distributed Clock is not currently supported on Parker E Series drives, but it is not required for operation. If the Distributed Clock is enabled on the EtherCAT Slave, the Scan Engine will not successfully transition to Active Mode.

- For support configuring the E Series drive as well as wiring questions, visit parkermotion.com/support.htm.
- Updated plug-in code to improve CPU performance.
- Fixed an issue where Read Faults would return repeated data.
- Removed workaround fix to CAR 583192 where smoothing was not applied to Find Reference move acceleration as this has been fixed in newer versions of SoftMotion.
- Home Reference Moves are limited to 2 options. See note in Find Reference section above for more details.
- Index Reference Moves do not use the homing acceleration value.
