Explanation
0 No line voltage
1 Normal operation without fault
No enable = OFF
1
Terminals "D1" - "24 V" (Digital In 1) not bridged.
Temperature management active
The device has an active temperature manage-
ment to protect it from damage due to too high
1
inside temperatures. In case of a temperature rise
above the fixed limits, the modulation is reduced
linearly.
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
0
phase) the unit switches off after a delay (approx.
200 ms).
Only functioning with an adequate load for the
controller.
Motor blocked
If after 8 seconds of commutation no speed is
measured > 0, the fault "Motor blocked" is re-
0
leased.
Failure power module
Short circuit to earth or short circuit of the motor
winding.
0
Intermediate undervoltage
If the DC-link voltage drops below a specified limit
the device will switch off.
0
Intermediate circuit overvoltage
If the DC-link voltage increases above a specified
limit, the motor will switch off.
0
Reason for excessively high input voltage or alter-
nator motor operation.

Reaction of Controller
Line voltage available?
Unit switch OFF and automatically ON when the
voltage has been restored
Switch OFF by external contact (see digital input).
With a drop in temperature the modulation rises
again llinear.
Check installation of the device and cooling of 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
EC-Controller 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.
EC-Controller switches off, renewed attempt to
start after about 60 sec. see code 9.
Final shutoff, if - following a second starting test –
a second fault detection is detected within a peri-
od of 60 seconds.
It is then necessary to have a reset by disconnect-
ing the line voltage.
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.
If the DC-link voltage drops below the limit within
75 seconds, then the cotroller will attempt to start.
Should the DC-link voltage stay above the limit for
more than 75 seconds, the device will switch off
with a fault message.
