Trip codes
Version _AN
Trip codes appear on the upper line of the display.
Version _SL
The number given in brackets under each trip code (in the following list)
is the value that appears in parameter 10.20 . This can be read via serial
communications.
User defined trips
A user-defined trip can be created by setting parameter 10.38 at 1 to 255
(but not 100 ) via serial communications. The value entered in 10.38 then
appears in 10.20 ; if 10.38 is set at a value that corresponds with an
existing trip (e.g. 1 ), the cause of the trip will be interpreted accordingly
(e.g. if 1 is used, it will be interpreted as UU Insufficient DC-bus
voltage).
•
Setting parameter 10.38 at 100 resets the Drive
•
Setting parameter 10.38 to 255 resets the trip log

Ramps not being used
•
0.26 Deceleration rate value too low
•
Incorrect value of braking resistor
Excessive instantaneous output current caused by a

too low or a short-circuit.
Internal power supply fault.

Remove and re-connect the AC supply. If the trip
persists, contact the supplier of the Drive.
Parameter 10.38 has been set at 6 (via serial
communications) to indicate an External trip .

Correct the cause of the trip and reset the Drive.
The motor has exceeded the over-speed threshold.
This can be caused by the following:

•
Sudden removal of a large mechanical load
•
0.26 Deceleration rate value too low
•
Inappropriate setting for 0.27 Fast ramp select
