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 "
Error codes in G1_XIST2" on page 61
.
Format definition:
• 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.
For the format example see G1_XIST1 above.
