User Manual of A90 Series Inverter 153 24 Undervoltage status When the DC bus voltage (F18.08) is less than or equal to the voltage of undervoltage stall control (F07.08), the current output will be valid; when the DC bus voltage (F18.08) is greater than or equal to the voltage of power failure end judgment (F07.10), and the holding time is greater than or equal to the determined delay time of power failure end, the current output will be invalid. 25 Motor overheat pre-alarm If the current motor temperature (F18.38) is greater than or equal to the motor overheat pre-alarm threshold (F07.05), the current output will be valid; otherwise, the output will be invalid.
See the description of the function codes F07.03 to F07.05. 26 Up to the set time When it reaches the regular running time, the current output will be valid; otherwise, the output will be invalid. See the description of the function code F16.09. 27 Running at zero speed When the inverter is in the JOG or slave running status and the output frequency (F18.00) is less than or equal to the zero servo start frequency (F04.29), the current output will be valid; otherwise, the current output will be invalid. 28-37 Reserved 38 Off-load The inverter is in the off-load status.
39-46 Reserved 47 PLC output When this function is selected for the output terminal, the output of Y1, Y2, R1, R2 and Y3 will be controlled by the corresponding bit of F03.31. If the corresponding bit is 1, the output will be valid; and if the corresponding bit is 0, the output will be invalid. 59 Sleep indicator This is dedicated to water supply applications. When the water pump meeting the sleep conditions is in the sleep status, the output of this function will be valid. 69 FDT1 lower limit (pulse) This is similar to #3/4 function. The difference is that the output will be valid when the frequency is lower than the “setting-hysteresis” and automatically turn invalid after some time.
If the single pulse output is set, the time will be set by F03.17 to F03.20; and if the level output is enabled, the time is 0.1 s by default. 70 FDT2 lower limit (pulse) 71 FDT1 lower limit (pulse, invalid in JOG) This function is the same as #69/70 function, except for no output in the JOG status. 72 FDT2 lower limit
