Page 20: Parameters
The parameters listed in this chapter are used for programming and monitoring the SM- Encoder Plus and SM-Encoder Output Plus The SM-Encoder Plus and SM-Encoder Output Plus are classed as dumb modules as they do not have their own processors, and as a result all parameters are updated by the drive processor. - Page 21 User save: saved in drive EEPROM when the user initiates a parameter save.
