7 Configuring an
Application
7.1 Introduction
All applications using SM-EZMotion modules are
configured using PowerTools Pro configuration software.
For specific questions on PowerTools Pro operation,
please refer to “PowerTools Pro Configuration Software”
on page 7 of this manual.
The hierarchy in PowerTools Pro gives the user a basic
template on how to configure an application. The user
should start at the top of the hierarchy, filling out necessary
parameters on the different views, working all the way to
the bottom of the hierarchy. Once the user is more familiar
with the software, they may choose to skip various views.
By following the hierarchy from top to bottom, the user will
start by configuring the hardware that the SM-EZMotion
module will be used with (Drive Type, Motor Type, etc.).
The user will then configure the different Setup views for all
the different configuration parameters (i.e. User Units,
Tuning, PLS, Torque Limits, etc.). Next, the user
configures the Digital and Analog I/O for the drive,
SM-EZMotion module, and any SM-I/O Plus modules. The
user then defines all of the different motion profiles (Jogs,
Homes, Indexes, Gears) to be used in the application. After
the hardware, setup parameters, I/O, and motion have
been configured, the user writes programs to tie the entire
application together. Once the programs are complete, the
user can create the interface for Modbus communications
to the different drive/module parameters.
7.2 Define Hardware
7.2.1 Drive/Encoder View
The Drive/Encoder view allows the user to configure the
Drive Type and Encoder Type being used in the
application. Figure 53 shows the Drive/Encoder view.
7.2.1.1 Drive Type
The Drive Type list box show the available Unidrive SP
models.
7.2.1.2 Motor Type
The Motor Type list box shows the available motors in the
.ddf file.

7.2.1.3 Motor Configuration (Servo/Closed-loop
Vector)
7.2.1.3.1 Drive mode Selection List Box
The Unidrive SP is capable of running in different operating
modes. These modes are as follows:
1. Open Loop Mode (Volts/Hz)
2. Open Loop Vector Mode
3. Closed Loop Vector Mode
4. Servo Mode
5. Regen Mode
However, the SM-EZMotion module is only able to control
the drive while in modes 3 and 4 listed above (Closed-loop
Vector Mode and Servo Mode). The user must select which
operating mode their application will use in the Drive mode
list box. Based on the setting of this parameter, many
different views and tabs within PowerTools Pro will change
to use the appropriate parameters. When this selection is
changed, the user will be taken to the Motor Tab on the
Drive/Encoder view so that the necessary motor
parameters can be entered.
The SM-EZMotion module will also automatically change
the drive mode to match the mode selected in this list box
on every power-up or warm start.
