Fault Codes (continued)
Action, Reset, and Corrective Action
Action Level Start counting when output current > 150% of the motor 3 rated current�
P14�81 (If the output current is larger than 105% of the motor 3 rated
Action Time current again within 60 sec�, the counting time reduces and is less than
P14�81)
Fault setting
N/A
parameter
Reset method Manual reset
Reset condition Reset in five seconds after the fault is cleared
Record Yes
1) Reduce the load�
2) Increase the setting value for P01�12–P01�19 (accel�/decel� time)
3) Adjust the settings for P01�54–P01�61 (V/F curve), especially the
setting value for the mid-point voltage (if the mid-point voltage is set
too low, the load capacity decreases at low speed)� Refer to the V/F
curve selection of P01�43�
4) If the EoL3 only occurs during low-speed operations:
a) Replaced the drive with a dedicated VFD model�
b) Increase the motor capacity�
Corrective 5) If using a VFD dedicated motor, verify P14�80=1: Standard motor
Actions (motor with fan on the shaft)�
6) Verify motor rated current and reset if needed�
7) Verify motor rated frequency and reset if needed�
8) If using one drive to run multiple motors, set P14�80=2: Disable, and
install thermal relay on each motor�
9) Set stall prevention to the proper value�
10) Adjust P07�73 torque compensation gain until the current reduces
and the motor does not stall�
11) Check the status of the fan, or replace the fan�
12) Replace the motor�
