220 EZMotion User/Programming Guide
www.controltechniques.com Revision: A8
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 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 check box, found on the Analog Outputs view, is used to enable the specific analog output channel for use by EZMotion. If the
check box is clear, the analog output is not being used by EZMotion, and the user is free to use it with alternate methods. However,
once the enable check box is activated (selected), the user should not attempt to use the analog input from another module or from
the keypad. When the check box is activated, several other configuration parameters will become available.
Drive Analog Output X Maximum Output Value
SPAnalogOutput.#.MaxOutputValue
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.
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
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.
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 Minimum Output Value
SPAnalogOutput.#.MinOutputValue
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.
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.
Drive Analog Output X Minimum User Value
SPAnalogOutput.#.MinUserValue
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.
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 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 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, click on the Popup Variables button and
the Select Variables From Tree window opens. 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.
