Temperature management active
The device has integrated active temperature
management to protect the device from damage
caused by excessively high interior temperatures.
In case of a temperature increase above the pre-
determined limits the modulation is linearly re-
duced.
With a drop in temperature the modulation rises
again llinear.
Check installation of the device and cooling of the
motor.

Error rotor position
Determination of the rotor position has failed.
After 8 starting tests, an error message is dis-
played.
Check whether the motor can rotate freely (with-
out line voltage).

Line failure
(only for 3 ~ types)
The device is provided with a built-in phase-mon-
itoring function for the mains supply. In the event
of a mains interruption (failure of a fuse or mains
phase) the unit switches off after a delay (approx.
200 ms).
Only functioning with an adequate load for the
controller.
Following a shutoff, a startup attempt is made
after approximately 15 seconds, if the voltage
supply is high enough. This keeps occurring until
all 3 supply phases are available again.
Check power supply.

Motor blocked
If after 8 seconds of commutation no speed is
measured > 0, the fault
“

is re-
leased.
Device switches off, renewed attempt to start after
about 2.5 sec.
Final shutoff, when fourth starting test fails.
It is then necessary to have a reset by disconnect-
ing the line voltage.
Check if motor is freely rotatable.

Failure power module
Short circuit to earth or short circuit of the motor
winding.
EC-Controller switches off, renewed attempt to
start after about 70 sec. see code 9.
Final shutoff, if - following a second starting test
–
a second fault detection is detected within a peri-
od of 75 seconds.
It is then necessary to have a reset by disconnect-
ing the line voltage.

Intermediate undervoltage
If the DC-link voltage drops below a speci
fi
ed limit
the device will switch off.
If the DC-link voltage rises above the limit within
75 seconds, then the cotroller will attempt to start.
Should the DC-link voltage stay for more than
75 seconds below the limit, the device will switch
off with a fault message.
