2 Protective Functions This chapter explains the "PROTECTIVE FUNCTIONS" that operate in this product. Always read the instructions before use.
2.1 Inverter fault and alarm indications When the inverter detects a fault, depending on the nature of the fault, the operation panel displays an error message or
warning, or a protective function is activated to shut off the inverter output. When any fault occurs, take an appropriate corrective action, then reset the inverter, and resume the operation. Restarting
the operation without a reset may break or damage the inverter. When a protective function is activated, note the following points.
Inverter fault or alarm indications are categorized as follows.
NOTE The last 10 faults can be displayed on the operation panel. (Fault history) (For operation, refer to page 12.)
Item Description
Fault output signal Opening the magnetic contactor (MC) provided on the input side of the inverter at a fault occurrence shuts off the control power to the inverter, therefore, the fault output will not be retained.
Fault or alarm indication When a protective function is activated, the operation panel displays a fault indication.
Operation restart method While a protective function is activated, the inverter output is kept shutoff. Reset the inverter to restart the operation.
Displayed item Description
Error message A message regarding operational fault or setting fault on the operation panel is displayed. The inverter output is not shut off.
Warning The inverter output is not shut off even when a warning is displayed. However, failure to take appropriate measures will lead to a fault.
Alarm The inverter output is not shut off. An Alarm (LF) signal can also be output with a parameter setting. Fault When a protective function is activated, the inverter output is shut off and a Fault (ALM) signal is output.

2.2 Reset method for the protective functions Reset the inverter by performing any of the following operations. Note that the accumulated heat value of the electronic thermal relay function and the number of retries are cleared (erased) by resetting the inverter. The inverter recovers about 1 second after the reset is released.
On the operation panel, press the STOP/RESET key to reset the inverter. (This may only be performed when a fault occurs. (Refer to page 22 of the Instruction Manual for faults.))
Switch the power OFF once, then switch it ON again.
Turn ON the Reset (RES) signal for 0.1 s or more. (If the RES signal is kept ON, "Err" appears (blinks) to indicate that the inverter is in a reset status.)
NOTE OFF status of the start signal must be confirmed before resetting the inverter fault. Resetting an inverter fault with the start
signal ON restarts the motor suddenly.

2.3 Check and clear of the fault history The operation panel stores the fault indications which appear when a protective function is activated to display the fault record for the past 10 faults. (Fault history)
Check for the fault history
*1 When an overcurrent trip occurs by an instantaneous overcurrent, the monitored current value saved in the fault history may be lower than the actual current that has flowed.
*2 The cumulative energization time and actual operation time are accumulated from 0 to 65535 hours, then cleared, and accumulated again from 0.

Operation panel indication Err.
Description The RES signal is turned ON. This error may occur when the voltage at the input side of the inverter drops.
Corrective action Turn OFF the RES signal.
Operation panel indication OLC FR-LU08 indication OL
Description
When the output current of the inverter increases, the stall prevention (overcurrent) function is activated. The following section explains about the stall prevention (overcurrent) function.
During acceleration
When the output current (output torque under Real sensorless vector control or Vector control) of the inverter exceeds the stall prevention level (Pr.22 Stall prevention operation level, etc.), this function stops the increase in frequency until the overload current decreases to prevent the inverter from resulting in overcurrent trip. When the overload current is reduced below stall prevention operation level, this function increases the frequency again.
During constant- speed operation
When the output current (output torque under Real sensorless vector control or Vector control) of the inverter exceeds the stall prevention level (Pr.22 Stall prevention operation level, etc.), this function reduces frequency until the overload current decreases to prevent the inverter from resulting in overcurrent trip. When the overload current is reduced below stall prevention operation level, this function increases the frequency up to the set value.
During deceleration
When the output current (output torque under Real sensorless vector control or Vector control) of the inverter exceeds the stall prevention level (Pr.22 Stall prevention operation level, etc.), this function stops the decrease in frequency until the overload current decreases to prevent the inverter from resulting in overcurrent trip. When the overload current is reduced below stall prevention operation level, this function decreases the frequency again.
Check point
Check that the Pr.0 Torque boost setting is not too large. The Pr.7 Acceleration time and Pr.8 Deceleration time settings may be too short. Check that the load is not too heavy. Check for any failures in peripheral devices. Check that the Pr.13 Starting frequency is not too large. Check that Pr.22 Stall prevention operation level is appropriate.
Corrective action
Gradually increase or decrease the Pr.0 setting by 1% at a time and check the motor status. Set a larger value in Pr.7 and Pr.8. Reduce the load. Try Advanced magnetic flux vector control, Real sensorless vector control, or Vector control. Change the Pr.14 Load pattern selection setting. The stall prevention operation current can be set in Pr.22 Stall prevention operation level. (The initial value
is 150% for the ND rating.) Acceleration/deceleration time may change. Increase the stall prevention operation level with Pr.22 Stall prevention operation level, or disable stall prevention with Pr.156 Stall prevention operation selection. (Use Pr.156 to set either operation continued or not at OLC operation.)

Description
When the output voltage of the inverter increases, the stall prevention (overvoltage) function is activated. The regeneration avoidance function is activated due to excessive regenerative power of the motor. The following section explains the stall prevention (overvoltage) function.
During deceleration If the regenerative power of the motor becomes excessive to exceed the regenerative power consumption capability, this function stops decreasing the frequency to prevent overvoltage trip. As soon as the regenerative power has reduced, deceleration resumes.
Check point Check for sudden speed reduction. Check if the regeneration avoidance function (Pr.882, Pr.883, Pr.885, and Pr.886) is being used.
Corrective action The deceleration time may change. Increase the deceleration time using Pr.8 Deceleration time. Reference manual FR-E800 Instruction Manual (Function)
