5.4.15 ReadMeasValue
Function: Reads the TMS temperature, motor temperature, motor current, measured rotational speed,
and control unit temperature. The motor temperature value is the same temperature as
"ReadMotorTemp". The measured rotational speed value is the same as "ReadMeas" parameter 2
(Measured rotational speed).
