F08 W*
Motor
overheated
- Too high ambient temperature
- Ball bearings are firm
- Rotor unbalance
- Rotor is blocked
- Electronics defective
- Observe the manufacturer's
operating and environmental
conditions
- Let the motor cool down after
eliminating the cause
- Lower the ambient temperature
- Correct the operating point
- Manual reset required
130 5
F09 W*
Hall sensor
defective
- A speed or position detection
required for the operation of the
EC fan is faulty or defective
- Switch off the mains voltage
- Wait
- Switch on again
- Replace the fan (please contact
the manufacturer)
130 6
F10 W*
Motor is
blocked
- Fan blades iced up
- Other impurities prevent the fan
from starting
- Switch off, make voltage-free +
check
- Eliminate the cause of the motor
blocking
- Check the fan blades for possible
errors
- Balance the rotor if necessary
130 7
F11 W*
Limit speed
exceeded
- Exceeding a fixed, maximum
speed
- Check set parameters
- Parametrize again if necessary
130 8
F12 W*
Overcurrent /
overload peak,
I²T
- The actual motor current or the
motor current calculated over
time is too high
- If a defined limit value is
exceeded, the system switches off
- Reduce the volume flow
- Reduce the speed
- Clean the rotor
- Change defective bearings if
necessary
F13 W*
Calibration
error of rotor
position sensor
- Incorrect initialization
- An automatic restart follows
130 10
F14 W*
Intermediate
circuit
overvoltage
- The intermediate circuit voltage
has risen above a specified value
- Input voltage is too high
- Braking too quickly (generating
operation)
- Check the power supply
- Extend the ramp times
130 12
F15 W*
Intermediate
circuit
undervoltage
- The intermediate circuit voltage
has fallen below a specified value
- Mains phase missing
- Check the power supply
F16 W*
Mains
overvoltage
- Mains voltage is too high
- Check the applied mains voltage
F17 W*
Mains
undervoltage
- Mains voltage is too low
- Check the applied mains voltage
F18 W* Communication
interrupted
- No communication between
TCS.2 and fan possible
- Check the wiring of the
communication bus
- Check terminal points
- Check the power supply of the
fan
