How do I set the MECHATROLINK station address for the JOHB-SMP3 option?

The station address for MECHATROLINK communication is set using parameter F6-20, and you must cycle power on the drive after changing the parameter for it to take effect. For MECHATROLINK-4 (JOHB-SMP3), the valid range is 0000h to FFEFh, with a default of 0021h. If set to 0000h, the option uses the station address from when the previous cyclic communication was established; on first use, it defaults to 0021h. All station addresses must be unique, as incorrect settings will cause AEr [Station Address Setting Error] errors. (Page 6)
