• The parameters n074, n075, and n076 are used to set the overtorque detection function.
• Select
with n074 whether to permit the
Inverter to detect overtorque and a method to process the over
-
torque.
• The
Inverter will detect overtorque if the output current as large as or larger
than the detection level set
with n075 flows for a period as long as or longer than the detection time set with n076.
• Set
with n075 an overtorque detection current level in
1% units based on the rated output current as
100%.
• Set with n076 overtorque detection time in 1-s units.
• Refer to
page 3-77
to permit the Inverter to output an overtorque detection signal as multi-function
contact output.
Set Values (n074)
Set value Description
0 Inhibits Inverter from detecting overtorque.
1 Inverter will detect overtorque only during speed agreement and continue running with a
warning after detection.
2 Running Inverter will detect overtorque and continue running with a warning after detection.
3 Inverter will detect overtorque only during speed agreement and turn OFF output for safety
when overtorque is detected.
4 Running Inverter will always detect overtorque and turn OFF output for safety when overtorque
is detected.
n077 Timer Function ON Delay Time
Setting range 0.0 to 25.5 Unit s Default setting 0.0
n078 Timer Function OFF Delay Time
Setting range 0.0 to 25.5 Unit s Default setting 0.0
• The parameters n077 and n078 are used to set the timer function.
• To
permit the Inverter to use the timer function, set the multi-function input parameter used by the In
-
verter
to 20 for timer function input and the multi-function contact output parameter used by the Invert
-
er to 11 for timer function output.
• Set
with n077 delay time in1-s units to permit the Inverter to turn ON timer function
output after timer
function input is ON.
• Set
with n078 delay time in 1-s units to permit the Inverter to turn OFF timer function output after timer
function input is OFF.
• Refer to
page 3-71, Timer Function Input (Set Value = 20)
for the timer function in detail.
