Fault Causes Solutions
E ‐ Thermal
(Electronic
Thermal
Overload, ETH)
The internal electronic
thermal overload protection
of the drive has determined
that the motor is overloaded
and/or over heated.
Check fault history. DRV ‐ 13 if still tripped,
AFN ‐ 01 if reset.
Note the amps and frequency recorded
when the trip occurred. Inspect load and
motor for causes of high current draw.
ETH settings too low. Check/Adjust motor settings and ETH levels:
DRV ‐ 05 through DRV ‐ 08
AFN ‐ 40 motor capacity.
Motor was operated at low
speeds for extended period
of time.
If low speed operation is normal, options
are:
Turn off low speed ETH (FUN ‐ 09 to forced
cool) and add separate motor cooling fan.
Turn of ETH completely (FUN ‐ 06, No) and
use FUN ‐ 66, 67 and 68.
Incorrect motor capacity
selected.
Select correct motor capacity (AFN ‐ 40,
Motor select).
Incorrect drive capacity
selected.
Select correct drive capacity (MAK ‐ 01,
Inverter capacity).
Incorrect V/F pattern. Select correct V/F pattern (FUN ‐ 40) or
operating mode (AFN ‐ 60).
Load is too large for the
rating of the drive.
Reduce Load and/or Increase drive capacity.
