0000h Temperature data. The temperature sensed in the device at the time the Log Sense command is performed
is returned in the Parameter field defined by this parameter code. The one-byte binary value specified the
temperature of the device in degrees Celsius. Temperatures equal to or less than zero degrees Celsius is
indicated by a value of zero.
If the device server is unable to detect a valid temperature because of a sensor failure or other condition, the
value returned is FFh. The temperature should be reported with an accuracy of plus or minus three Celsius
degrees while the device is operating at a steady state within the environmental limits specified for the drive.
No comparison is performed between the temperature value specified in parameter 0000h and the reference
temperature specified in parameter 0001h.
0001h Reference temperature data. A reference temperature for the drive may optionally be provided by the drive
using parameter code 0001h. If no reference temperature is provided, the parameter may not be provided in
the log page or alternatively, the reference temperature value may be set to the value of FFh. The one-byte
binary value reflects the maximum reported sensor temperature in degrees Celsius at which the drive will
operate continuously without degrading the drive's operation or reliability outside the limits specified by the
manufacturer of the drive. The reference temperature may change for vendor-specific reasons.
