User Manual of EM730 Series Inverter 178 frequency source to AI1 the function code F00.04 Table 7-3. 53 Switching of main frequency source to AI2 55 Switching of main frequency source to high-frequency pulse input 56 Switching of main frequency source to communication setting 57 Inverter enabling When the inverter meets the operating conditions and the current function terminal is valid, the inverter is able to run. Otherwise, it will not run even if other operating conditions are met. ★: Inverter enabling function:
If no terminal is selected, this function is valid by default; if one terminal is selected, the status of the selected terminal will prevail; and if more than one terminal is selected and any selected terminal is invalid, this function will not be valid. 58 - 67 Reserved 68 Prohibition of reversing disabling It is only applicable to the straight wire drawing machines in winding applications. 1: When the function of 69# input terminal is available and/or F00.21=1, 68# input terminal is available, and reversing disabling is prohibited, that is, reversing is allowed; otherwise, reversing disabling is not prohibited, that is, reversing is not allowed. 2:
When the function of 69# input terminal is available and/or F00.21=1, 68# input terminal is available, and reversing is disabled, that is, reversion is not allowed; otherwise, reversing disabling is not disabled, that is, reversing is allowed. 69 Prohibition of reversing When this terminal is valid, its function is the same as that in the case of F00.21=1. 70 Input terminal extension When input terminal extension is set to this function, the digital input terminals X1~X5 of the frequency converter can be used as the extended input terminals of PLC and other peripheral devices.
Whether the corresponding input terminal is valid can be obtained by reading the input terminal status of F18.22 71 - 78 Reserved 121 External material This is a dedicated function for winding applications, which is
