4PARAMETERSUseful functions(3) Setting of Pr. 557 Current average value monitor signal output reference currentSet the reference (100%) for outputting the signal of the current average value. Obtain the time to output the signalfrom the following formula.Output current average value × 5s (output current average value 100%/5s)Pr. 557 settingNote that the output time range is 0.5 to 9s, and it is 0.5s when the output currentaverage value is less than 10% of the setting value of Pr. 557 and 9s when exceeds180%.Example)When Pr. 557 = 10A and the average value of output current is 15AAs 15A/10A × 5s = 7.5, the current average value monitor signal is outputas low pulse shape for 7.5s.(4) Output of Pr. 503 Maintenance timerAfter the output current average value is output as low pulse shape, themaintenance timer value is output as high pulse shape. The output time of themaintenance timer value is obtained from the following formula.Pr. 503 × 100× 5s (maintenance timer value 100%/5s)40000hNote that the output time range is 2 to 9s, and it is 2s when Pr. 503 is less than16000h and 9s when exceeds 72000h.REMARKS⋅ Mask of data output and sampling of output current are not performed during acceleration/deceleration.⋅ When the speed is changed to acceleration/deceleration from constant speed during start pulse output, the data is judged asinvalid, the start pulse is output as high pulse shape for 3.5s, and the end signal is output as low pulse shape for 16.5s.The signal is output for at least 1 cycle even when acceleration/deceleration state continues after the start pulse output iscompleted.Output frequencyThe speed is changed to deceleration fromthe constant speed during start pulse outputSignal output timeSignal output time(s)90.510 180 (%)Output current average value(s)9216000 72000 (h)Maintenance timer value⋅⋅Previous cycleY93signal2) Start pulseOutput as highpulse shape for3.5sInvalid cycle (20s)TimeNext cycle5) End signalOutput as low pulseshape for 16.5sWhen the output current value (inverter output current monitor) is 0A on completion of the 1 cycle signal output, the signal is notoutput until the speed becomes constant next timeThe current average value monitor signal (Y93) is output as low pulse shape for 20s (without data output) under the followingcondition.(a)When the motor is in the acceleration/deceleration state on completion of the 1 cycle signal output(b)When 1-cycle signal output was ended during restart operation with the setting of automatic restart after instantaneous powerfailure (Pr. 57 ≠ "9999")(c)When automatic restart operation was being performed with automatic restart after instantaneous power failure selected (Pr.57 ≠ "9999") on completion of the data output mask⋅CAUTIONChanging the terminal assignment using Pr. 190 to Pr. 196 (output terminal function selection) may affect the other functions.Please make setting after confirming the function of each terminal.♦ Parameters referred to ♦Pr. 190 to Pr. 196(output terminal function selection) Refer to page 214Pr. 503 Maintenance timer Refer to page 357Pr. 57 Restart coasting time Refer to page 239359
