2.3.2 Link functions (operation selection) 2-19 2.3 Switching to Communications According to the setting of function code H30: Serial link (function select), the frequency setting and the operation command source (via-communications command or command selected by function codes F01/C30 and F02 when communications is valid can be selected. Frequency setting done when the communications is valid and selection of operation source are influenced by the settings at y98, y99. For details, see Fig 2.9.

FRENIC-MEGA is equipped with RS-485 communications port 2 (terminal base) as standard equipment. By selecting continuous communications valid without setting any digital input terminal, and switching the data of H30 to communications valid/invalid (external signal input valid), communications valid/invalid can be switched in the same manner as switching at the digital input terminal. See the next section or later. Chap. 2 COMMON SPECIFICATIONS
2.3.3 How to switch communications enabled/disabled To issue a frequency setting or operation command through communications to control the inverter, select "Through RS-485 communications" by function code H30: link function (operation selection). In addition, when switching control through communications with control from the terminal block (frequency setting from terminal [12], operation command from terminal [FWD] and so on) to switch remote operations with operations on the inverter body, assign "link operation selection" (data = 24: "LE") to the function code related to the digital input terminal (one of E01-E05: terminals [X1] to [X5], E98: terminal [FWD], or E99: terminal [REV]). (FRENIC-Mini does not support E04, E05, [X4], and [X5].) Control can be switched by the terminal to which "link operation selection" (data = 24: "LE") is assigned. Communications automatically becomes valid when link operation selection is not assigned to any digital input terminal. Table 2.5 Digital input terminal settings and communications statuses Input terminal Status OFF Communications invalid ON (short-circuited to Communications valid the terminal [CM]) - Via-communications command data and operation data must be rewritten from the host (controller) because the memory is initialized when the power is turned ON. - Although command data and operation data can be written even if communications is invalid, they will not be validated because the switch is made invalid by link operation selection. If communications is made valid with no operation data written (operation command OFF, frequency setting = 0Hz) during operation, the running motor decelerates to a stop and may exert impact on the load depending on the set deceleration time. Operation can be switched without causing impact to the load by setting data in communications invalid mode in advance and then switching the mode to valid. - If negative logic is set as Link enable (data 1024), the logical value corresponding to the ON/OFF status of the command "LE" will be reversed. - FRENIC-Eco/Multi/MEGA has the field bus option other than RS-485 communications. The field bus option is handled prior to RS-485 communications depending on the setting of it in some cases. For details, see the function code "y98 Bus function (function selection)" of each inverter type. 2-20
