AH500 Motion Control Module Manual 3.12 Special Auxiliary Relays and Special Data Registers 3.12.1 Special Auxiliary Relays Special auxiliary relays (SM devices) and special data registers (SR devices) are shown in the tables below. Some device numbers in the tables are marked with *. Users can refer to section 3.13 for more information. If the attribute of a device is “R”, the users can only read data from the device. If the attribute of a device is “R/W”, the users can read data from the device, and write data into the device. In addition, “-” indicates that the state of a special auxiliary relay is unchanged, or the value in a special data register is unchanged.

“#” indicates that a special auxiliary relay or a special data register in an AH500 series motion controller is set according to the state of the AH500 series motion controller. The users can read a setting value, and refer to the manual for more information. 3-14 Applicable model*1 OFF STOP RUN SM Function    Attribute Default number 05M 15M 10M 20M ON RUN STOP 000* If the module runs, SM000 will be a normally-open contact (Form A contact).
