Hi everyone,
The inverter restarts automatically, be careful of the machine because it may suddenly restart.
Err1 Frequency point setting error alarm The frequency setting signals at points 1 and 2 are set too close to each other. Set the frequency setting signals at points 1 and 2 apart from each other.
Cler Clear command acceptable This message is displayed when pressing the STOP key while an error code is displayed. Press the STOP key again to clear the trip.
H1oFF Emergency stop command acceptable The operation panel is used to stop the operation in automatic control or remote control mode. To cancel the emergency stop, press any other key.
AH Setting error alarm An error found in a setting when data is reading or writing. Check whether the setting is made correctly.
HErrd Display of first/last data items The first and last data item in the RUN data group is displayed. Press MODE key to exit the data group.
db DC braking DC braking in progress. The message goes off in several tens of seconds if no problem occurs. Note 1
Ldb Flowing out of excess number of digits The number of digits such as frequencies is more than 4. (The upper digits have a priority.) Reduce the frequency to be less than 100 Hz.
Stp Momentary power failure detection and trip stop prohibition function activated The slowdown stop prohibition function selected with F306 (momentary power failure ride-through operation) is activated. To restart operation, reset the inverter or input an operation signal again.
tEP Auto-tune because continuous operation selected The automatic tune function selected with F65 was activated. Check the operation. When frequency reaches LL or operation signal is input, normal operation starts.
Iinit Parameters in the process of initialization Parameters are being initialized to default values. Normal if the message disappears after several seconds.
P-01 Points setting alarm 1 In case of P-1, there are same setting value at least two parameters of F190, F192, F193, F194, F195, F196, or F198 beep occurs. Set the points to different values.
R-02 Points setting alarm 2 In case of P-2, the inclination of V/f is too high. Set the inclination of V/f to flat.
R-05 Output frequency upper limit An attempt was made to operate at a frequency higher than 10 times the base frequency (set to F103). Operate at a frequency within 10 times the base frequency.
R-17 Operation panel key (RUN or STOP key) pressed too long The RUN or STOP key is held down for more than 20 seconds. Check the operation panel.
R-28 ST terminal alarm Slide switch SW2 and parameter F147 settings are different. Match the settings of SW2 and F147. Power supply OFF and ON after these settings.
Rt Auto-tuning Auto-tuning in process. Normal if the message disappears after a few seconds.
AL5 Break in analog signal cable The input signal from VIC is below the analog signal detection level set with F633 and setting value of F634 is 1 or more. Check the cable for breaks. Check the setting of input signal or setting value of F633 and F634.
Fire In forced operation F1-F7 and operation frequency is displayed alternately in operation of forced free-speed control. It is normal as the alarm is gone out after the forced free-speed control operation.
Pr STOP signal OFF STOP terminal is in open-circuit. Close STOP and S-CC circuit.
PAS Password verification result After the password setting (F738), the password is read. F739 (password verification). If the password is correct, PAS is displayed and if it is incorrect, P1 is displayed.
EASy Switching display of easy setting mode/standard setting mode The EASy key was pushed in the standard monitor mode. When F459 is displayed, setting mode becomes easy setting mode. When Std is displayed, it becomes standard setting mode.
SEt Region setting of SEt mode A region setting is not input yet. Power supplied to the inverter at first time as checking the region setting parameter SEt is set to 0, inverter return to default setting. Set a region setting by using setting dial. Refer to section 3.1.
SEt2 Note SEt is blinking after power supply is on. In this time, the keys are not operated. SEt parameter SEt is lighting is same as other parameters and is not blinking.
nErr No trip of past trip No record of past trip, after past trips were clear. Normal operation.
- - - - No detailed information of past trip The detailed information of past trip is read by pushing the enter of setting dial during blinking nErr = number. Normal operation. To be returned by pressing MODE key.
Prealarm Display
C Overcurrent alarm Same as OC (overcurrent) Same as OC (overcurrent)
P Overvoltage alarm Same as OP (overvoltage) Same as OP (overvoltage)
l Overload alarm Same as OL1 and OL2 (overload) Same as OL1 and OL2 (overload)
OH Overheat alarm Same as OH (overheat) Same as OH (overheat)
t Communication alarm Same as Err5 (communication fault) Same as Err5 (communication fault)
If two or more problems arise simultaneously, one of the following alarms appears and blinks.
CP, PL, t
The blinking alarms C, P, L, t are displayed in this order from left to right.
