P rocedure 2: Power On and Checking Network Establishment
9 0 B
The power-on procedure is as follows.
4. Turn on the power supplies for input and output devices connected to the PLC.
5. Turn on the power supply for the AMP.
6. Turn on the power supply for the PLC.
After the power turned on, check if the operation status display LEDs of the positioning unit RTEX is in
the following state.
STATUS : Lights up
LINK
: Lights up
Key Point:
• If the STATUS LED is blinking, the network is not established.
• If the LINK LED is off, the connection between the "RX" of the positioning unit RTEX (receiver) and the
"TX" of the AMP (sender) is not electrically correct.

P rocedure 3: Matching Parameters With AMP
9 1 B
At the factory setting, the operating directions of the positioning unit RTEX and the AMP are
different as below.
• Parameters of positioning unit RTEX : CW direction is elapsed value (+) direction
• Parameters of AMP
Therefore, they must be matched according to the following procedures.
1. Boot the Configurator PM and set the corresponding axis.
2. Specify the "Select slot" from the "Online" on the menu, and select the slot number that the positioning
unit RTEX is installed.
3. Specify the "Download to unit" from the "File" on the menu, and down the axis information and
parameter setting data.
4. The indication for writing into the FROM (flash memory) is shown. Select "Yes" to carry out writing to
the FROM.
5. After the completion of writing, turn off the power supplies of AMP and PLC, and then turn them on
again.
6. After turning on the power supplies again, the system will be operated with the parameters set in the
positioning unit RTEX.
Key Point:
Followings are the parameters to match the operating directions of the positioning unit RTEX and AMP
according to the above procedure.
"CW/CCW direction setting"
"Limit switch connection"
As these parameters are important to establish the system, they will be reflected to the operation of a
motor by turning on the power supply again after writing them into the FROM (flash memory) of the
positioning unit RTEX.
