SMA1
Output code
The sensor provides the absolute position information in the desired code
format: GRAY (0) or BINARY (1).
Default = 1 (Binary)
Counting direction
The
standard counting direction
is to be intended with sensor moving as
indicated by the arrow in Figure 1. This parameter allows to reverse the counting
direction. In other words it allows the count up when the sensor moves in
reverse of the standard direction, i.e. in the opposite direction to the one shown
by the arrow in Figure 1. It is possible to choose the following options:
STANDARD (0) and INVERTED (1). When the counting direction is set to
STANDARD -
= STANDARD-, the position information
increases when the sensor moves according to the arrow in Figure 1. When the
option INVERTED is set -
information increases when the sensor moves in reverse of the standard
direction, i.e. in the opposite direction to the one shown by the arrow in Figure
1.
Default = 0 (Standard)
NOTE
parameter affects the absolute position information,
not the sine/cosine signals.
The new setting will be active immediately after transmission. Use the
function (set “01” in the register 48) to store the new
value.
register default value =
20h
Absolute resolution
[4D, rw]
It allows to read and set the resolution of the absolute sensor.
64hex :
Resolution = 0.1 mm
(max position = 00 FF FFh, 16 bits)
32hex :
Resolution = 0.05 mm
(max position = 01 FF FFh, 17 bits)
0Ahex :
Resolution = 0.01 mm
(max position = 07 FF FFh, 19 bits)
05hex
: Resolution = 0.005 mm
(max position = 0F FF FFh, 20 bits)
The new setting will be active immediately after transmission. Use the
function (set “01” in the register 48) to store the new
value.
NOTE
If the preset / offset functions are active, after having set a new value next to
this
register, then you must check the value in the
