Processing • By turning on i_bEN (Execution command), the set positioning data is written to the buffer memory.
• If the setting value of the target axis is out of the setting range, o_bErr (Error completion) turns on and the processing of this
FB is interrupted. In addition, the error code 100 (hexadecimal) is stored in o_uErrId (Error code). For the error code, refer to
Page 8 Error code.
• If the setting value of the positioning data No. is out of the setting range, o_bErr (Error completion) turns on and the
processing of this FB is interrupted. In addition, the error code 101 (hexadecimal) is stored in o_uErrId (Error code). For the
error code, refer toPage 8 Error code.
