For operation with run control:
For operation without run control:
Space from proximity switch to rotor
Change the controller programming
Connect the proximity switch to the controller
(see run control description)
V-belt jumps off
V-belt over or under tension
Even though controller signal is present, this appears:
Placement of the jumpers according to description
The controller is set to manual mode
Is the controller signal there?
Connect controller signal to controller (polarity!)
Fault codes:
In addition to the run control fault and motor overtemperature, the controller 7 also recognizes different faults.
These faults are indicated in the display with a two place error code:
E : x x !
or
A c t . f r e q . : 0 0 H z
N o m . f r e q . :
0 0 H z
A c t . f r e q . : 8 0 H z

01
Overvoltage (motor / rotor blocked, short circuit between U, V, W)
05
Overload (controller / motor overloaded)
09
Mains under voltage
14
Earth fault
15
Mains overvoltage
21
Overtemperature in the power amplifier, environmental temperature too high, controller overloaded
99
Software error
The controller is again operation-ready when the fault is erased by removal of the error via interruption of the
mains voltage or by pressing all three buttons at the same time.
Caution!
When using a restart mode integrated into the software, the controller does not go directly to fault with over- or
undervoltage and overcurrent. Rather, it tries within 10 minutes to reset itself. If a reset takes place within the
10 minutes, the controller continues to run in normal mode. If the KR4/7 cannot reset itself during a longer
lasting malfunction, after 10 minutes a fault message occurs on the fault message outlet and the fault indicator
appears on the controller display.
Warning
This function causes an independent restart of the frequency converter along with the drive if there is still a
malfunction after the expiration of a set wait time – when a start command is still there. In the case of a restart,
ensure that no people are endangered.
