*1  The maximum number of errors may differ depending upon the software version of the STP pump. It is recommended that 
an application be designed as variable-length data. 
*2  Value corresponding to the error message is transmitted (refer to Table 24 and Table 25). The most recent error has the 
largest parameter number. When the number of errors being detected is under the maximum number, the value of 
parameter that is larger than the number of errors being detected is set to 0.
