G1_Xist2 - Datalogic AMT58 Series Manual

G1_XIST2

[Unsigned, 32 bits]
It is defined as Sensor 1 current position value 2. By default this signal is the current
(real) absolute position of the encoder expressed in binary notation yet it has a different
meaning if an error is active.
If no error is active:
this signal informs about the current position value of the encoder, provided that the bit
Request absolute value cyclically (bit 13 of control word G1_STW) is set to 1; otherwise
this value is 0.
If an error is active:
this signal informs about the active error. For the complete list of the error codes refer
to "

For the format example see G1_XIST1 above.
all values are represented in binary notation;
the recommended default shift factor is zero (right aligned value) for both G1_X-
IST1 and G1_XIST2;
the settings in the encoder parameter data affect the position value in both G1_X-
IST1 and G1_XIST2;
G1_XIST2 displays the error telegram instead of the position value if an error
occurs.
