P2 Recovery Time (2x.061) is the time that must be allowed after each message interchange
before a new message begins.

During position feedback Initialization, the transmission delay between the position feedback
interface and the encoder and back again is measured and stored in P2 Line Delay Time (2x.062).
This value is then used to compensate for this delay so that the clock/data skew does not prevent
the data from the encoder from being read.
This means that longer line lengths can be used with these feedback devices provided the correct
cable and connection arrangements are used.
P2 Device type (2x.038): Any other type of device
P2 Line Delay Time (2x.062) is always zero.

If the position can be sampled in 60 μs, P2 Low Speed Update Rate Active (2x.063) = 0, otherwise
P2 Low Speed Update Rate Active (2x.063) = 1.
The following parameters are used by the drive to determine the time required to obtain the data
from the position feedback device:
P2 Rotary Turns Bits (2x.033)
P2 Comms Bits (2x.035)
P2 Comms Baud Rate (2x.037)
P2 Calculation Time (2x.060)
P2 Recovery Time (2x.061)
P2 Line Delay Time (2x.062)
P2 User Comms Enable (2x.067)
See P1 Low Speed Update Rate Active (1x.063) for more information on how this time is
calculated.
* BiSS is not currently supported.
