Error messages
ERROR calc. drive data 60
Error: During the automatic motor stator resistance mea-
surement.
ERROR output phase fail. 5 Phase loss detection at the output
Error blockade 26
A blockade was recognized.Pn85 Bit 4 is at error, no
auto-reset.
ERROR brake 56
Error can occur with activated brake control (see chapter
brake control) if:
• the load during the start is below the min. load level
(Pn43) or the missing of a motor phase was detected.
• the load is too high and the hardware current limit is
reached.
ERROR speed ctrl. lim 25 Speed controller limit reached
ERROR ow control 27
The ow control is activated in Pn91. No input and out-
put for valve control is selected in Pn92 and Pn93.
ERROR input error detect 53 Hardware error at start/stop measurement.
ERROR external fault 31
Is triggered, if a digital input is being programmed as
external error input and trips.
ERROR
overspeed
58
The speed is outside the dened limits. (can also occur
on exceeding of the absolute speed referring to EMF =
EMF wrong (servo drives).
ERROR overheat internal 6
Overheating in the interior. Error can only be reset at
"no ERROR overheat int." if the interior temperature has
dropped by at least 3 °C
ERROR load shunt fault 15
Load-shunt relay has not picked up, occurs for a short
time during the switch-on phase, but must automatically
be reset immediately. If the error message remains the
following causes may be applicable:
• load-shunt defective
• input voltage wrong or too low
• high losses in the supply cable
• braking resistor wrongly connected or damaged
• braking module defective
ERROR power unit 12 Error: General power circuit fault
ERROR motor protection 30 Electronic motor protective relay has tripped.
ERROR max. accelerati-
on
24 Maximum acceleration exceeded
ERROR drive overheat 9
Error: Overtemperature of motor PTC. Error can only be
reset at "no ERROR drive overheat“ if PTC is again low-
resistance. Causes:
• Resistance at terminals T1/T2 >1650 Ohm
• Motor overloaded
• Line breakage to the temperature sensor
