The following items are Bug Fixes in the LabVIEW 2018 SoftMotion Module.
| ID | Fixed Issue | Issue Details |
|---|---|---|
| 621339 | SoftMotion Set Plugin Mode VI does not have detailed help available | The Set Plugin Mode VI offers no detailed or context help to explain which actions take place when called. |
| 643434 | SoftMotion Drive Interface (SDI) Axis position cannot be reset following a home move | After a homing sequence on an SDI Axis, the EtherCAT drive will report a position of 0. SoftMotion will display an axis position error of the last known position. This position error cannot be reset with the Reset Position method. |
| 667021 | SoftMotion Set Plugin Mode VI does not transition to Configuration mode if an error is passed to the error input | The error handling inside the SoftMotion Set Plugin Mode VI does not correctly discard input errors and will fail to transition to Configuration mode if an error is passed to it. |
| 685409 | Using more than 16 SDI Axes may fail to transition to Active mode | For most SDI Plug-ins, using more than 16 SDI Axes on one controller will fail to transition to Active mode. |
| 667023 | Manually changing an SDI Axis operating mode may cause a position jump | SDI Axes can operate in four move modes (homing, velocity, torque, position). While operating in homing, velocity, and torque modes, the position setpoint is not updated in SoftMotion's trajectory generator. When switched back to position mode manually the position error is calculated as the last known position and the current feedback position and causes the axis to rapidly change position. |
| 612846 | SoftMotion Express VIs cannot be used with more than one coordinate resource | When using the SoftMotion Express VI API to command moves with Coordinate Spaces, do not wire two different Coordinate Spaces to the resource input of one Express VI. |
| 639822 | LabVIEW RT can crash when property nodes of different resources are called in parallel | When repeatedly calling property nodes in parallel for different SoftMotion resources, LabVIEW RT can crash. The chance of this happening is low and is mitigated by calling SoftMotion property nodes in series. |
| 645028 | UDV Axes fail to link when containing subset of another axis name | When using the UDV Axis type, the axis names must be unique identifiers without repeating a subset of the name. For instance, Axis 1 is contained in Axis 10, and Axis 10 will not behave correctly if used in the same project. |
| 640148 | Duplicate examples for the 9501 module in LabVIEW Example Finder | The Example Finder contains duplicate lists of examples for the 9501 stepper drive module. This is cosmetic, as one half of the examples will open, and the other half will fail to open. |
| 657386 | SoftMotion Read or Write Digital Line does not range check for out of range index values | Using a negative line index for the SoftMotion Read or Write Digital Line Express VI or method will cause LabVIEW RT to crash. |
| 657377 | Ethernet Stepper Read Digital Line on SMD-761x drives gives bad data | The SMD-761x Ethernet Stepper drives provide additional digital inputs compared to the ISM-741x Ethernet Integrated Stepper Motors. Digital lines X4-X8 do not provide correct data. |
| 654932 | NI 9503 example code will result in SoftMotion fault 8780 if run for an extended period of time | The FPGA code contained in the NI 9503 example projects has the maximum jitter value set too low and will eventually fault if left running for an extended period of time. |
| 667024 | After a Find Reference Move, a SoftMotion Axis will not correctly enable gearing when commanded | Following a Find Reference Move on an axis, SoftMotion will not transition the operating mode of the axis back to position mode. This prevents the Gear In method from executing. |
| 667009 | Read Analog Data does not throw an error when used with an Ethernet Stepper axis | Ethernet Stepper Drives do not support the Read Analog Data method. Read Analog Data will return a value of 0 instead of an error if used with an Ethernet Stepper axis. |
| 676856 | SoftMotion returns Error -77124 when commanding an axis move following a coordinate contour move | When executing a series of moves (a coordinate straight line move and a coordinate contour move, followed by an axis straight line move), SoftMotion will return Error -77124. |
| 679833 | LabVIEW RT will crash if two SoftMotion closed-loop stepper axes both encounter an unrecoverable stall | The SoftMotion stepper drive interface axis type can be configured for closed-loop behavior. If the position error during a move exceeds the threshold for an unrecoverable stall on two axes at the same time, LabVIEW RT will crash. |
| 680471 | SoftMotion Gain Tuning Panel does not correctly set the Acceleration Jerk and Deceleration parameters of a straight line move | The SoftMotion Gain Tuning Panel allows straight line move parameters to be set directly, but the Acceleration Jerk and Deceleration parameters will be reversed. |
