Drive Analog Input X Minimum User Value
SPAnalogInput.#.MinUserValue
The SM-EZMotion reads the value of the analog input in
units of 0 to 100% and then scales that using linear
interpolation and then populates the specified destination
parameter/variable. When the analog input reaches the
Minimum Input Value, the destination variable will be equal
to the Minimum User Value. This is used as a point on the
curve for the linear interpolation.
Drive Analog Input X Maximum Input Value
SPAnalogInput.#.MaxInputValue
The SM-EZMotion reads the value of the analog input in
units of 0 to 100% and then scales that using linear
interpolation and then populates the specified destination
parameter/variable. When the analog input reaches the
Maximum Input Value, the destination variable will be
equal to the Maximum User Value. This is used as a point
on the curve for the linear interpolation.
Drive Analog Input X Maximum User Value
SPAnalogInput.#.MaxUserValue
The SM-EZMotion reads the value of the analog input in
units of 0 to 100% and then scales that using linear
interpolation and then populates the specified destination
parameter/variable. When the analog input reaches the
Maximum Input Value, the destination variable will be
equal to the Maximum User Value. This is used as a point
on the curve for the linear interpolation.
Drive Analog Input X Module Variable
SPAnalogInput.#.ModuleDestination
The analog input is read it units of 0 to 100%. That value is
then scaled and put into a destination variable of the users
choice. This parameter is used to define which variable
within the SM-EZMotion module is the destination for the
analog input. This can be any read/write parameter within
the SM-EZMotion. For a list of the parameters, please refer
to the Program – Drag In Variables tree.
Drive Analog Input X Raw Value
SPAnalogInput.#.RawValue
This parameter is read only and shows the value of the
analog input before it is scaled into the user scaling.
Therefore, the raw value will always range between 0%
and 100%. This parameter can be found on the Analog
Input view but is only functional while online with the
SM-EZMotion module.
Drive Analog Input X Set Minimum Input Value
SPAnalogInput.#.SetMin
This button can be found on the Analog Input view next to
the Minimum Input text box. When this button is pressed,
the SM-EZMotion reads the current value of the Analog
Input and writes that value into the Minimum Input text box.
This allows the user to easily set the analog input to its
minimum scale value and enter that value into the text box
avoiding direct calibration of the input circuitry.
Drive Analog Input X Set Maximum Input Value
SPAnalogInput.#.SetMax
This button can be found on the Analog Input view next to
the Maximum Input text box. When this button is pressed,
the SM-EZMotion reads the current value of the Analog
Input and writes that value into the Maximum Input text
box. This allows the user to easily set the analog input to
its full-scale value and enter that value into the text box
avoiding direct calibration of the input circuitry.
Drive Analog Input 2 Mode
SPAnalogInput.2.InputMode
Analog Inputs 2 and 3 on the Unidrive SP can function in a
number of different operation modes. By default, Analog
Input 3 is used for thermistor protection of the motor, and
therefore is not accessible on the Analog Inputs view. By
default, the mode for Analog Input 2 is set to Voltage Mode.
From this list box, the user can select from: Voltage Mode,
0-20mA Mode, and 4-20mA Mode. This is available so that
the analog inputs can be used in nearly any possible
application.
Drive Analog Output X Channel Enable
SPAnalogOutput.#.ChannelEnable
This checkbox, found on the Analog Output view, is used
to enable the specific analog output channel for use by the
SM-EZMotion module. If un-checked, the analog output is
not being used by the SM-EZMotion, and the user is free to
use it with alternate methods. However, once the enable
checkbox is activated (checked), the user should not
attempt to use the analog input from another module or
from the keypad. When the checkbox is activated, several
other configuration parameters will become available.
Drive Analog Output X Minimum Output Value
SPAnalogOutput.#.MinOutputValue
The SM-EZMotion can read the value of a specified
parameter and scale it into the Unidrive SP’s scale of 0 to
100% of scale on the output. The SM-EZMotion uses linear
interpolation to scale the value properly. When the
selected source parameter is equal to the Minimum User
Value, then the Analog Output will be equal to the Minimum
Output Value. This parameter is used in conjunction with
the Minimum User Value to define a single point on the
curve used for linear interpolation.
