08- 24 Operation Selection of External Fault
Range
【0】：Deceleration to Stop
【1】：Coast to Stop
【2】：Continous Operation
When multi-function digital input terminal is set to 25 (the external fault) and this terminal
signal is triggered off, parameter 08-24 (Operation Selection of External Fault) can be selected
to stop it. The selection of stop modes is the same as 07-09.
08- 25 Detection Selection of External Fault
Range
【0】：Immediately Detect when the Power is Supplied
【1】：Start to Detect During Operation
The reson for the detection of external faults is determined by parameter 08-25.
(1) When 08-25=0, faults are immediately detected at power up.
(2) When 08-25=1, fault are detected when the inverter is running.

Motor Overheat Fault Selection：
It executes motor overheat protection by the resistor (PTC) that built-in the motor.
The resistor (PTC) is between AI2 and GND and a divided resistor R ,as the pic 4.3.65(b)
(1) When motor occurs overheating：
08-35 = 0：Motor overheats fault function is off.
08-35 = 1：When the motor is overheating, it coasts to stop.
08-35 = 2：When the motor is overheating, it free runs to stop
08-35 = 3：When the motor is overheating, it keeps running until reach the value of 08-42
(2) 08-35=1 or 2, if the temperature is getting higher for the motor and AI2 voltage level is
higher than the value of 08-44, the display will show 『OH4 Motor Overheating』 and the motor
will stop by 08-35=1 or 2.
(3) 08-35=3, When the temperature is getting higher for the motor and AI2 voltage level is higher
than the value of 08-44, the display will show 『OH3 Motor Temp Warning』but the motor
continues running. But AI2 voltage level is higher than the value of 08-42 and the time reach to
08-39, the motor free runs to stop.
(4) When 08-35 = 1 or 2 or 3，When the motor cools down and AI2 voltage level is lower the value
of 08-43, 『OH4 Motor overheat』will reset.
