Where encoder comms is used for initial setting of absolute position (SC.Hiper or SC.EnDat), the comms resolution in bits must be set correctly, either
by the user or the drive (see Pr x.17 on page 234), in Pr x.11. The comms resolution may be higher than the resolution of the sine waves per
revolution.
Where encoder comms alone is used the encoder single turn comms resolution (Pr x.11) and the encoder turns bits (Pr x.09) must be set correctly.
Although Pr x.11 can be set to any value from 0 to 32, if the value is less than 1, the resolution is 1 bit. Some SSI encoders include a power supply
monitor alarm using the least significant bit of the position. It is possible for the drive to monitor this bit and produce an EnC6 trip if the power supply
is too low (see Pr x.17 on page 234). If the encoder gives this information the comms resolution should be set up to include this bit whether or not it is
being monitored by the drive.
It is possible for the drive to set up this parameter automatically from information obtained from the encoder via HIPERFACE or EnDat interfaces (see
Pr x.18 on page 234).

This bit should be set if the Solutions Module is connected to a motor thermistor and the user wants the temperature to be checked. The Solutions
Module will trip for over temperature and thermistor short circuit.

This parameter defines the baud rate for the encoder comms when using SSI or EnDat encoders. However, a fixed baud rate of 9,600 baud is used
with HIPERFACE encoders and this parameter has no effect.
