Speed Feedback Selector
SpeedFeedbackSelector
This parameter is used to define the location of the Motor Feedback Source connection. This parameter allows direct access
to parameter 3.26 from the Unidrive SP frequency/speed configuration menu, and can be found on the Setup View. Valid
selections from this list are Drive, Slot1, Slot2, and Slot3. This parameter was hard-coded to "Drive" in early revisions of
software and firmware, meaning that the motor feedback had to be connected to the Unidrive SP Encoder Port. This
parameter must be set up correctly, otherwise EZMotion will not properly receive position information from the motor.
SPInput Status
SPInput.#.In
The last three digital I/O points on the drive are defined as digital inputs only (pins 27, 28, and 29). The ".In" at the end of the
parameter is optional, so this signal is most often referred to simply as SPInput.#. These inputs can be used in a user
program, or on the Assignments view to activate different destination events.
These inputs are updated at the Trajectory Update Rate found on the Setup view in PowerTools Pro.
SPInput Name
SPInput.#.Name
Each digital input on the drive can be given a name. The name can be used in a user program to reference a specific input if
desired. The name can be up to 12 alphanumeric characters, but must begin with a non-numeric character.
SPIO Direction
SPIO.#.Direction
The first three digital I/O points on the Unidrive SP(pins 24, 25, and 26) are configured as Inputs or Outputs using PowerTools
Pro software. The SPIO.#.Direction parameter is used to configure whether the I/O point acts as a digital input or digital output.
Valid entries for this parameter are selInput or selOutput. This parameter is modified automatically when the user changes the
settings on the SP I/O Setup view.
SPIO Status
SPIO.#.In
The first three digital I/O points on the Unidrive SP(pins 24, 25, and 26) are configured as Inputs or Outputs using PowerTools
Pro software. If the I/O points have been configured as digital inputs, then the SPIO.#.In signal can be used in a user program
to check the status of inputs, or on the Assignments view to activate different signals. If assigned to a destination on the
assignments view, when the digital input activates, the destination that it is assigned to will also activate.
NOTE
This parameter will appear on the Assignments view under the Inputs group of Sources even if the I/O point has been
configured as a digital output.
SPIO Name
SPIO.#.Name
Each digital I/O point on the Unidrive SP can be given a name. The name can be used in a user program to reference a
specific I/O point. The name can be up to 12 alphanumeric characters, but must begin with a non-numeric character.
SPIO State
SPIO.#.Out
The first three digital I/O points on the Unidrive SP (pins 24, 25, and 26) are configured as Inputs or Outputs using PowerTools
Pro software. If the I/O points have been configured as digital outputs, then the SPIO.#.Out signal can be used in a user
program to activate an output, or on the Assignments view to activate when a specified Source event activates. If assigned to
a source on the assignments view, when the source event activates, the output that it is assigned to will turn on.
NOTE
This parameter will appear on the Assignments view under the Outputs group of Destinations even if the I/O point has been
configured as a digital input.
SP Menu Decimal
SPMenu.Decimal
This parameter is used behind the scenes in PowerTools Pro when reading or writing to a SP menu parameter using the Drive
Watch Window. These are not to be used inside a user program.
If writing to or reading from a Unidrive SP menu parameter in a program, use the Menu.MM.PP instruction instead. In this
