User Manual of EM730 Series Inverter Once the set frequency (F00.07) is set to 50.00Hz, the above data will be valid but not be stored in EEPROM. That is, the inverter will run at 50.00Hz after change but at the frequency before change if powered on again. 1.1.1.6 0x10: function code used to write multiple registers or commands (1 to 16 registers). In the remote terminal unit, this function code is used to write consecutive register blocks The value requested to be written is described in the request data field. The data of each register is divided into two bytes. will be returned.
