•Overtorque Detected (Setting：11)
•See page 56, 76 for overtorque detection function.
•Frequency Command Missing (Setting：12)
•Run source is ON and frequency command is 0, the output at the multi-function
output terminal is ON.
•Fault (Setting：13)
•If a fault occurs, the multi-function output terminal is ON. However, no response
will occur if a communication fault occurs.
•Pulse Signal Output (Setting:14)
•Only multi-function output terminal DO1-DOG (Setting Sn-31) can be set as the
pulse signal output.
•DO1 is a photo-coupler output, its pulse output frequency is set by parameter
Sn-35.
•Its wiring is:
DO1
DOG
DO2
+V (12V or 24 V)
T1
T2
pulse duty (T1=T2)

•Undervoltage Alarm (Setting：15)
•If the main circuit DC bus voltage is below the undervoltage alarm detected
level, the multi-function output terminal is ON.
•Undervoltage alarm detected level : 220V Class : 240VDC
440V Class : 460VDC
•Inverter Overheat (Setting：16)
•See Page 106. If the cooling fin is overheat, the multi-function output terminal
is ON.
•Motor Overload (Setting：17)
•See “Motor overload protection selection” on page 79. If the motor has overload
fault, the multi-function output terminal is ON.
•Inverter Overload OL2 (Setting：18)
•
If the inverter has overloadfault, the multi-function output terminal is ON. See page 106.
