#2(BZA): The battery voltage for the stand–alone type pulse coder is zero.
#1(PMA): A pulse error occurred in the stand–alone type pulse coder.
#0(SPH): A soft phase data error occurred in the stand–alone type pulse coder.

#7(DTE): A data error occurred in the stand–alone type pulse coder.
#6(CRC): A CRC error occurred in the stand–alone type pulse coder.
#5(STB): A stop bit error occurred in the stand–alone type pulse coder.
This data indicates the cause of servo alarm No. 417, detected by the NC.
If the alarm is detected by the servo, the PRM bit (bit 4 of DGN No. 0203)
is set to 1.

#0(MOT): The motor type specified in parameter No. 2020 falls outside the
predetermined range.
#2(PLC): The number of velocity feedback pulses per motor revolution, specified in
parameter No. 2023, is zero or less. The value is invalid.
#3(PLS): The number of position feedback pulses per motor revolution, specified in
parameter No. 2024, is zero or less. The value is invalid.
#4(DIR): The wrong direction of rotation for the motor is specified in parameter No.
2022 (the value is other than 111 or –111).
#6(AXS): In parameter No. 1023 (servo axis number), a value that falls outside the
range of 1 to the number of controlled axes is specified. (For example, 4 is
specified instead of 3.) Alternatively, the values specified in the
parameter are not consecutive.
