Drive Analog Output X Minimum User Value
SPAnalogOutput.#.MinUserValue
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 Output Value to define a single point on the
curve used for linear interpolation.
Drive Analog Output X Maximum Output Value
SPAnalogOutput.#.MaxOutputValue
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 Maximum User
Value, then the Analog Output will be equal to the
Maximum Output Value. This parameter is used in
conjunction with the Maximum User Value to define a
single point on the curve used for linear interpolation.
Drive Analog Output X Maximum User Value
SPAnalogOutput.#.MaxUserValue
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 Maximum User
Value, then the Analog Output will be equal to the
Maximum Output Value. This parameter is used in
conjunction with the Maximum Output Value to define a
single point on the curve used for linear interpolation.
Drive Analog Output X Module Variable Source
SPAnalogOutput.#.ModuleSource
If User Defined Module Variable is selected from the
Source list box, then the user must define which variable
from within the SM-EZMotion is to be used as the source
for the analog output. When the user selects a variable, the
current value of that variable will constantly be used to
update the value of the analog output. For a list of variables
that can be used, refer to the Drag In Variables pop-up
window in the Program view. Any 16-bit or 32-bit parameter
can be used as the source variable.
Drive Analog Output X Mode
SPAnalogOutput.#.OutputMode
This parameter is used to define the operating mode of the
specific Analog Output. Available modes are 0-20mA,
4-20mA, High Speed, and Voltage Modes. By default, the
output will function in Voltage Mode. In order to work in
High Speed mode, only a few select source parameters
can be selected. These are detailed as “High Speed” in the
Source list box.
Drive Analog Output X Scale
SPAnalogOutput.#.Scale
The Scale parameter is only available if the user has
selected User Defined SP Menu from the Source list box.
The Scale parameter ranges from 0.000 to 4.000 and is
multiplied with the selected SP Menu Parameter to achieve
the ultimate output value. This parameter directly accesses
7.20 or 7.23 depending on the specific analog output
channel.
Drive Analog Output X Source
SPAnalogOutput.#.Source
This parameter is used to define the source value for the
given analog output channel. The user can select from the
following choices:
Predefined Module Variables
Following Error
Velocity Command
Velocity Feedback
User Defined Module Variable
User Defined SP Menu
Predefined Fast Mode Parameters
Menu 3.02 (Speed)
Menu 4.02 (Active Current)
Menu 4.17 (Magnetizing Current)
Menu 5.03 (Output Power)
Based on which Source parameter is selected, different
scaling parameters will become available. When the
Fast Mode parameters are selected, there are no
scaling parameters available. Also, when selecting any
of the four fast mode parameters, the Analog Output
Mode must also be set to Fast Mode.
Drive Analog Output X SP Parameter Source
SPAnalogOutput.#.SPMenuSource
If User Defined SP Menu is selected from the Source list
box, then the user must define which parameter from within
the Unidrive SP Menu structure is to be used as the source
for the analog output. When the user selects a parameter,
the current value of that parameter will constantly be used
