Overtorque Detected (Setting：11); Pulse Signal Output (Setting:14); Inverter Overheat (Setting：16); Motor Overload (Setting：17) - TECO speecon 7200ma Instruction Manual

•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:
•Undervoltage Alarm
•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
•Inverter Overheat (Setting：16)
•See Page 106. If the cooling fin is overheat, the multi-function output terminal
is ON.
•Motor Overload
•See "Motor overload protection selection" on page 79. If the motor has overload
fault, the multi-function output terminal is ON.
•Inverter Overload OL2
•If the inverter has overloadfault, the multi-function output terminal is ON. See page 106.
