EXAMPLE
Vdc = +24V
I = 30mA (current needed to energize
a small relay coil)
R2 = 750
No encoder error = coil energized.
Encoder error = coil de-energized.
6 – TEACH-IN procedure
The TEACH-IN function allows to easily and
intuitively set (by means of two keys or, as an
alternative, two external signals) both the
furthermost points in the travel of an axis, then the
available analogue range will be scaled
automatically within the set limits.
6.1 Commissioning
To start the TEACH-IN procedure, simultaneously
press both START
and STOP
keys and hold
them down for 5 seconds (be careful not to exceed
10 seconds; see the “6.4 Restoring the factory
default settings” section on page 15); both LEDs I
and II light up solidly. As soon as the keys are
released both LEDs start blinking. Likewise, you can
enter the TEACH-IN procedure by applying for 5
seconds a voltage greater than 10V to both START
and STOP inputs (see the “4 - Electrical connections”
and “5.5 Input signals description” sections).
You are allowed to set the initial
position first and then the final
position of the travel by pressing the
START
key first and then the STOP
key; otherwise you can do the opposite, i.e. you
can set the final position first and then the initial
position of the travel by pressing the STOP
key
first and then the START
key.
•
Turn the encoder shaft and move it to the
initial position START in the travel of your
application;
•
press the START
key for 2 seconds; data
acquisition is signalled by LED I solidly lit,
LED II keeps on blinking;
WARNING
from now on exit is inhibited until
completion of the process.
