Emerson P/N 400361-00 manual Mechanical Installation, Slot Selection, Electrical Connections

2 Installation

This section of the manual will cover basic installation information.

2.1 Mechanical Installation

Please refer to the Installation Sheet that comes with the SM-EZMotion module for details on installing the module into the Unidrive SP.

2.2 Slot Selection

The SM-EZMotion module may be placed in any of the three available option slots on the Unidrive SP. The user must indicate which slot the SM-EZMotion is fitted in using PowerTools Pro configuration software. The default slot number is Slot 3 in the configuration software.

2.3 Electrical Connections

The SM-EZMotion module has three separate terminal blocks used to access the different features. Figure 2 shows a diagram of these connections.

The terminals are numbered from Terminal 1 on the left to Terminal 7 on the right. The different terminal functions are listed in the table below.

Terminal #	Function	Description
1	OV Common	OV Common connection for
		digital I/O
2	Input1	Digital Input 1
3	Input2	Digital Input 2
4	Input3	Digital Input 3
5	Input4	Digital Input 4
6	Output1	Digital Output 1
7	Output 2	Digital Output 2

2.4 Digital I/O Connections

The SM-EZMotion module is equipped with 4 digital inputs and 2 digital outputs. The I/O are electrically sourcing I/O. All I/O utilize positive logic meaning that they are active when positive voltage is applied (10-30 VDC). See the Specifications section at the back of the manual for more detailed information on the digital I/O.

These digital I/O can be used to control different functions in the SM-EZMotion module. The digital I/O on the SM-EZMotion are updated at the SM-EZMotion Trajectory Update Rate. The Trajectory Update Rate can be found on

the Setup view in PowerTools Pro (see “Setup View” on page 37 for more information on the Trajectory Update Rate).

The digital I/O on the SM-EZMotion module are also unique (as compared to Unidrive SP digital I/O and SM-I/O Plus module I/O) because they can be used in the SM-EZMotion high speed capture process. Even though they are only updated once every Trajectory Update, the SM-EZMotion processor knows when they activate to within 1 microsecond. Therefore, when Capture is used, they can be accurate to 1 microsecond (see “Capture View” on page 46 for more information on the SM-EZMotion Capture object).

2.5Connecting Motor Encoder Feedback to the Unidrive SP

Figure 3 can be used to connect the encoder feedback signals for various different motors to the Unidrive SP. For further installation information, please refer to the Unidrive SP User Guide.
