EM58 PA
Position
It shows the current position information of the connected device. If Output
type
= VOLTAGE, then the current encoder position is expressed in Volts (V);
otherwise, if
Output type
= CURRENT, then the current encoder position is
expressed in milliamperes (mA).
Turns
It shows the number of revolutions already performed by the encoder. The value
can be represented in either decimal or hexadecimal format, click the DEC or
HEX option buttons in this box to choose the desired display format.
Counts/rev
It shows the current position information in the revolution. As soon as the
hardware number of information per revolution (namely, counts per revolution,
cpr: singleturn resolution) is achieved, the counter restarts again the increasing
count. The value is expressed in pulses. The value can be represented in either
decimal or hexadecimal format, click the DEC or HEX option buttons in this box
to choose the desired display format.
5.3.2 PRESET box
The functions in this box are activated and thus available only if the
Enable
preset
parameter in the
ENCODER CONFIGURATION
box is set to ENABLED; on
the contrary, if DISABLED is set, they are not available. The functions in this box
are used to set and activate the preset.
Preset
This function is available only if the parameter
Enable preset
in the
ENCODER
CONFIGURATION
box is set to ENABLED.
This parameter allows the operator to enter the preset value.
The Preset function is meant to assign a value to a desired physical position of
the encoder. The chosen physical position will get the value set next to this item
and all the previous and following positions will get a value according to it. This
function is useful, for example, when the zero position of the encoder and the
zero position of the axis need to match. The preset value will be set for the
position of the encoder (the current position is displayed next to the
Position
item in the
POSITION
box) in the moment when the preset value is activated. To
activate the preset, stop the encoder in the desired position and then press the
Activate preset
button in this box (otherwise connect the Preset input as
explained on page 25).
This parameter allows to enter decimal numbers with up to three digits
(thousandths); further digits in the fractional part are subject to round-off.
