Input >10Vdc : zero setting (min. 3,5
µ
s)
Input <8Vdc : function not enabled
Complementary (counting direction)
Allows to change counting direction by means of
an input signal. Status of the input is checked only
while switching on the encoder.
Input >10Vdc : counter clockwise counting
Input <8Vdc : clockwise counting (standard)
RXD, TXD (RS232)
Serial interface port for parameter settings and
data readAout.
RS232 parameters:
Baud rate = 9600 baud
Data = 8 bit, stop=1 bit
Flux control = Xon/Xoff
Parity
Allows to control functioning of encoder outputs
and connection integrity. Parity bit output is active
(high) when the sum of active output bits (high) in
even or odd (see parameter |EVEN and |ODD).
Latch
Allows the storage of the position value which the
encoder shows in output at a particular moment.
The above mentioned position value will remain
present in output until the LATCH signal is
deactivated. In this way it is possible, if for instance
the data transmission speed of the encoder is fast
in comparison to the data acquisition time of the
interface electronics, to freeze the position for the
amount of time necessary for the data to be
acquired.
Input >10Vdc: position freezed (Latch activated)
Input <8Vdc: Latch not activated
Tristate
Allows the transmission of output information from
the encoder to be blocked. In this it is possible to
work with several encoder in parallel (multiplexing)
using a single control unit, acquiring the
information values relative to the angular position
of each encoder with an updating time equal to the
duration of the multiplexing cycle.
Input >10Vdc : encoder enabled (Tristate activated)
Input <8Vdc : encoder not enabled (Tristate not
activated).
Preset1/Preset2
The Preset1 and Preset2 inputs are necessary for
the teachAin function of encoder resolution (see
PRST1 and PRTS2 parameters).
Input >10Vdc : teachAin activated
Input <8Vdc : teachAin not activated
