Description
This value is the incremental actual position value. G1_XIST1 corresponds to the number of
output pulses, which control the speed of the drive.
If an error has occurred, G1_XIST2 indicates the associated error code. For the meaning of
the error codes, see the table below.
When you use the "Reference mark search" function, this value returns the detected refer-
ence mark.
When you use the "Measurement on the fly" function, this value returns the acquired measur-
ing input value.
