9.1 Error code list
Error Cause Diagnostics and troubleshooting Res-
ponse
Ramp-up and/or ramp-down time too short Increase the ramp times in accordance with the
recommendations made in subsection 7.1.2
Quick commissioning incorrectly made The motor data entered in the parameters for quick
commissioning must match those of the motor in use
Permissible cable length exceeded Change the installation or use the recommended
output filters
Earth faults or short-circuit on motor supply line Test motor cable and, if necessary, replace it
Motor incorrectly connected Is the motor correctly connected (star / delta)?
Mechanically overloaded or blocked Motor must not be blocked or overloaded.
Calculation of the power currently delivered by the
motor shows whether the power effectively drawn
accords with the power indicated on the rating plate, or
whether the motor is mechanically overloaded:
P motor = r0027 * r0025 * root(3) * cosφ * η
F0001
Overcurrent
Motor power (P0307) exceeds VSD power
(P0206)
Compare the SED2’s rating plate with that of the motor
OFF2
Regenerative mode due to too short ramp-down
time
Increase the ramp-down time (P1121) or activate the
Vdc controller for the DC link (P1240)
Pulse frequency can lead to overvoltage (power
reflexions or electrical resonance)
− Increase the pulse frequency (P1800)
− In the case of high environmental temperatures,
improve cooling and/or deactivate automatic
derating of the pulse frequency
− Note drop in power depending on pulse frequency
(refer to Data Sheet on SED2, CM1N5192, page 6)
Firmware installed is 1.15 or 1.17 These firmware versions can trigger F0002 with no
reason. Install V1.41 or higher
Contact at the SED2’s output Ensure that the SED2 is started only when the switch
at the output is closed
Input voltage too high or transients or
interferences occur
Mains voltage must lie within the limits indicated on the
rating plate
If compensation equipment is installed, check its
function
Input choke Remove the choke
No mechanical load applied to motor shaft F0002 can occur when no load is applied to the motor
shaft
Regenerative mode due to active load Ensure that a fan / pump cannot be driven by some
other fan / pump (e.g. via a bypass damper or when a
fan is driven by 2 motors)
SED2 started before it reached standstill Make certain that the SED2 has come to a complete
standstill or activate “Flying start“ (P1200)
F0002
Overvoltage
Belt between motor and fan not tight enough,
producing slip
Check to ensure that the belt is correctly adjusted and
that it is not worn out or defective
OFF2
F0003
Undervoltage
Mains supply failed or outside specified limits Mains voltage must lie within the limits indicated on the
rating plate and must not be susceptible to short-time
power failures or voltage drops
OFF2
Built-in fan does not run Check to see if the fan is blocked or defective. Replace
it, if necessary
Mounting site more than 1,000 m above sea
level
The admissible power is reduced depending on the
elevation above sea level (refer to Data Sheet on VSD)
Ventilation not sufficient Set the pulse frequency (P1800) to a lower level
F0004
VSD over-
temperature
Environmental temperature higher than that
specified for the VSD
The admissible power is reduced depending on the
environmental temperature (refer to Data Sheet on
VSD)
OFF2
