Conditions
UU
1
Insufficient
DC
-bus voltage.
This occurs when the
AC
supply is removed.
OU
2
Excessive
DC
-bus voltage.
Excessive regenerated power caused by the following:
0.04 Deceleration rate value too low
Braking resistor not being used
Braking resistor not being used
OI.AC
3
Excessive output current caused by:
0.03 Acceleration rate value too low
0.04 Deceleration rate value too low
Excessive motor-cable capacitance
Short-circuit at the output of the Drive
0.04 Deceleration rate value too low
Excessive motor-cable capacitance
Short-circuit at the output of the Drive
OI.br
4
Excessive current in the braking resistor.
A short-circuit exists across the braking resistor.
PS
5
Internal power supply fault.
Remove and re-connect the
AC
supply. If the trip persists,
contact the supplier of the Drive.
Et
6
External trip signal applied to terminal 30.
Remove the trip signal, then reset the Drive.
OV.SPd
7
The motor has exceeded the over-speed threshold.
This can be caused by the following:
Sudden removal of a large mechanical load
0.04 Deceleration rate too low
Inappropriate
0.04 Deceleration rate too low
Inappropriate
0.16 Stop mode setting
0.19 S-ramp da/dt too high (not used in Macro 5)
