B. Overload
Fault Display:
Overload
Auto Resettable
: No
Related Parameters: DRV-05 Motor rated current
FUN-66 Overload Trip Selection Yes/No
FUN-67 Overload Trip Level
FUN-68 Overload Trip Time
Description
: General overload protection for the drive and the motor. The Overload Trip
function is activated with FUN-66 (set to Yes). The drive will trip when the drive output current
exceeds the Overload trip level (FUN-67, percentage of DRV-05) for the Overload Trip time
(FUN-68, seconds). Speed of the motor is not a factor (like Eth) using this overload protection.
Other Functionality:
A drive output relay (A1-C1, A2-C2, etc.) can be activated to provide a
remote signal when the drive trips on Overload. Program one of I/O-76 through I/O-79 to “OL”.
Additionally, a drive output relay (A1-C1, A2-C2, etc.) can be activated to provide an “OL
Warning” when programmed to the OL function (I/O-76 through I/O-79) along with parameters
FUN-64 (OL warning level) and FUN-65 (OL warning time).
Check Fault History:
At parameter AFN-01 (most recent fault), hit the program button, then up
arrow to view data captured at time of fault (Hz, Volts, Amps, Status). AFN-02 through AFN-05
are previous faults.
Fault Causes Solutions
Overload Drive output current is larger
than the overload settings.
Verify settings in FUN ‐ 66, 67 and 68. 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.
Load is too large for the
rating of the drive.
Reduce Load and/or Increase drive capacity.
Incorrect drive capacity
selected.
Select correct drive capacity (MAK ‐ 01,
Inverter capacity). Note when changing
MAK ‐ 01, the motor amps (DRV ‐ 05) will reset
to a default value based on MAK ‐ 01
selection.
Incorrect V/F pattern. Select correct V/F pattern (FUN ‐ 40) or
operating mode (AFN ‐ 60).
