Troubleshooting LPC motor controller
Error code No. Error Solution
no-Flt 0
No errors. -
O-I
3
Over current on the output
of the motor controller.
Power consumption of the
motor too high.
The motor controller can not be reset immediately. A
time delay is built in, see section
Resetting errors
[
}
46] .
I_t-trP 4
Motor thermal overload (I2t). Appears after delivering > 100 % of the value in set-
tings for a period of time to prevent damage to the mo-
tor.
O-volt 6
Over voltage on DC bus. Check that the supply voltage is within the allowed tol-
erance.
U-volt
7
Under voltage on DC bus. Supply voltage is too low. The error occurs if the supply
to the motor controller is interrupted. If the error occurs
during operation, check the supply voltage and all com-
ponents in the supply.
O-t
8
Over temperature on the
heat sink. The motor controller is too hot. Check that the ambient
temperature and distance requirements follow the
specification.
U-t
9
Under temperature. The temperature of the motor controller is below the
minimum limit, the temperature must be increased.
Flt-dc 13
Ripple voltage too high. Measure the supply phases.
P-LOSS
14
Phase error. Measure the supply phases.
h O-I 15
Over current on the output
of the motor controller.
Power consumption of the
motor too high.
The motor controller can not be reset immediately. A
time delay is built in, see section
Resetting errors
[ } 46] .
th-Flt
16
Defective thermistor on the
eat sink. Motor controller defective. Replace motor controller.
dAtA-F 17
Internal memory error (IO). Press the stop key. Contact SKOV A/S
Fan-F
22
Cooling fan error (IP66
only). Motor controller defective. Replace motor controller.
O-hEAt 23
Internal temperature of mo-
tor controller too high. Check that the ambient temperature and distance re-
quirements follow the specification.
Out-F
26
Output error. Check motor connections.
