Cause
K1*
Explanation
Cooling down period power module
Cooling down period power module for approx.
60 sec.
1
Final shutoff after 2 cooling-off intervals see code
6
Error motor start
If a starting command is given (enable available
and Setpoint > 0) and the motor does not start to
turn in the correct direction within 5 minutes, then
an error message will appear.
0
Line voltage too low
If the DC-link voltage drops below a specified limit
the device will switch off.
0
Line voltage too high
Cause to high input voltage
If the line voltage increases above a specified
0
limit, the motor will switch off.
Error peak current
If the motor current increases above the specified
limit (even in a short time-frame) the device will
0
switch-off.
Temperature alarm
Excess of the max. permissible inside tempera-
0
ture.
Communication fault
0
MODBUS communication interrupted
Reaction of Controller
Power module cooling down period for approx.
60 sec.
Final shutoff after 2 cooling-off intervals see code
6.
If it is possible to start the motor in the target
direction of rotation after the error message, the
error message will disappear
Should a voltage interruption occur in the mean-
time, the time taken up to the switch off will begin
again.
Check if motor is freely rotatable.
Check if the fan is driven in reverse direction by
an air stream (see Behaviour in rotation by air
current in reverse direction).
If the line voltage rises above a specified limit
within 75 seconds, then the controller will attempt
to start.
Should the line voltage stay below the specified
limit for more than 75 seconds, the device will
switch off with an error message
If the line voltage drops below the specified limit
within 75 seconds, then the controller will attempt
to start.
Should the line voltage stay above the specified
limit for more than 75 seconds, the device will
switch off with an error message.
After a switch off the controller waits for 5 seconds
then the controller attempt a start.
Arises within 60 sec. in series 5 further disconnec-
tions a final switch off with fault indication follows.
Should no further switch off be exceeded in
60 sec. the counter will be reset.
Controller switches off motor. Automatic restarting
after cooling down.
Check installation of the device and cooling of the
controller.
