Description of error
The parameterised fault input is active. 5010
The parameterised fault input is active. 5011
Motor identification error
The parameterised minimum / maximum
frequency has not been met / has been
exceeded.
Protection of the IGBT module against
overcurrent has been triggered
The maximum intermediate circuit voltage
has been exceeded
The minimum intermediate circuit voltage
has not been reached
Motor PTC has been triggered
The supply voltage has dropped briefly
Excess IGBT module temperature
Maximum output current of drive controller
exceeded
Inner temperature too high
2
The internal I t motor protection (can be
parametrised) has been triggered
Ground leak during a motor phase
No motor current in spite of control through
frequency converter
Operating manual for DGM Modular | DOC02389740-0006 | 2021-07 | V1.70 EN
Possible causes/remedy
Correct the external error
Correct the external error
Check DGM Modular /motor and PC /
MMI / DGM Modular connections / restart
motor identification
The parameterised time 5.085 or 5.086 is
too short /
Motor blocked /
Brake not opened /
Motor overloaded
Short circuit in the motor or motor feed
line / controller settings
Feedback by motor in generator mode /
supply voltage too high / faulty setting for
rotation speed controller / brake resistor
not connected or defective / ramp times
too short
Supply voltage too low, grid connection
defective / check wiring
Overload of the motor (e.g. high torque at
low motor speed) / ambient temperature
too high
Grid fluctuation / grid
voltage interrupted
Insufficient cooling, low motor speed and
high torque, switching frequency too high
Motor stalled / check motor connection /
incorrect speed controller setting / check
motor parameters / ramp times too short /
brake not open
Insufficient cooling / low motor speed and
high torque / switching frequency too high
permanent overload / reduce ambient
temperature / check fan
Permanent overload
Insulation fault
No motor connected or not completely
connected.
Check phases or motor connections and
connect correctly when necessary.
