7 - Commissioning
In basic applications, you can use the TEACH procedure for commissioning of
the unit. Extended functions need a PC for set-up and are described later.
7.1 Self Test
Set all DIL switches according to your application and connect both the encoder
and the power supply to the unit. Set switch position 6 SSI-TEST to ON first (SSI
Test mode) and turn the power on. Both the green LED (power) and the yellow
LED (status) must light on. After a successful self-test, the yellow LED must
switch off again (approx. 1 sec.).
7.2 SSI signal test
Press the TEACH button once now. This will check the SSI Data lines. The yellow
LED must switch on. If it remains off, you need to cross the input lines “DATA+”
(9) and “DATA-“ (8).
Press the TEACH button one second time and the unit will test the SSI Clock
lines in the same manner. Again, the yellow LED must be lit, otherwise you need
to cross the lines “CLOCK+” (3) and “CLOCK-“ (2)
3 .
Press the TEACH button for the third time and the unit will switch the yellow
LED off and close the test cycle.
If the yellow status LED is lit after the first and the second time you press the
TEACH button, your encoder wiring is proper. Please switch the power off and
set DIL position 6 SSI-TEST to OFF to enable TEACH operation. Using a PC and
the OS3.2 operator software, you can check the status also in the OUTPUTS box
next to the STATUS SSI-CLK and STATUS SSI-DATA items (red = status is ok).
7.3 Scaling of the analogue output with use of the TEACH function
Switch the power on again, with DIL position 6 SSI-TEST set to OFF. Press the
TEACH button once.
The yellow status LED will start blinking at a slow frequency now while the unit
waits for the zero position (initial position) to be set. So move the encoder and
reach your preferred zero position output and then press the TEACH button
again.
This will store your zero definition and the LED will start blinking at a higher
frequency now while the unit waits for the full scale position (final position) to
be set. Move the encoder and reach your preferred full scale position output and
then press the TEACH button once more.
This will store your full scale definition and the LED will switch off. Your
analogue output is now set to the desired operating range, according to the
Output Mode
setting.
3 Testing the clock lines is primarily useful with Slave operation. Though the test works
also in Master mode, the result is only intended to show that the internal generation of the
clock works properly. However, with Master mode, this test cannot indicate faulty clock drivers
or bad wiring of the clock lines.
