1.4.6 Modbus error list
Table18: Modbus error list
No. Error text Type Description
0 No error Message No error
2 Motor temperature, shutdown Error The permissible motor temperature has been exceeded.
Resistance value PTC > trigger value (standard 4.5kΩ)
3 Motor temperature, rise too fast Error Excessively fast temperature rise in the motor winding.
Tripping occurred to avoid a large temperature overflow.
5 Undervoltage, shutdown Error Insufficient voltage was detected at the motor.
7 Switching frequency, shutdown Error The motor was switched off too often in the specified
period.
8 Motor temperature, short circuit Error A short circuit was detected at the motor temperature
input.
10 Motor temperature, interruption Error An open circuit was detected at the motor temperature
input.
21 Oscillation, shutdown Error The permissible vibration velocity on the vibration sensor
has been exceeded.
22 Vibration, sensor error Error Self-test of the internal vibration sensor has failed. Sensor
element defective or communication not possible.
23 Error short circuit sensor unit bus Error Error on the bus lines to the sensor unit (lines 3 and 4)
There is a short circuit to the shield.
24 Line error PTC analog channel Error Self-monitoring line error PTC analog channel detected
25 Analog channel PTC static
shutdown
Error Self-monitoring analog channel PTC static shutdown
detected
27 Wrong phase sequence Error An incorrect phase sequence was detected.
28 Phase failure Error Failure of one phase, and/or excessive percentage deviation
of one phase from the mean value of the 3 phases.
29 Phase asymmetry Error Excessive percentage deviation of one phase from the mean
value of the 3 phases.
31 Self-monitoring Error An error was detected during self-monitoring (e.g.
processor function), protection device must be replaced.
38 Motor temperature, shutdown Error The permissible motor temperature has been exceeded.
40 Underload, shutdown Error Insufficient effective power was detected at the motor.
41 Overload, shutdown Error Excessive effective power was detected at the motor.
46 Overvoltage Error Excessive voltage was detected at the motor.
55 Motor temperature, shutdown Error The permissible motor temperature has been exceeded. The
bimetal switch has tripped.
56 Temperature 1, shutdown Error Permissible temperature at temperature input exceeded.
Resistance value PTC > trigger value (standard 4.5kΩ)
57 Temperature 1, shutdown Error Permissible temperature at temperature input exceeded.
58 Temperature 1, short circuit Error A short circuit was detected at the temperature input.
59 Temperature 1, interruption Error An open circuit was detected at the temperature input.
60 Temperature 2, shutdown Error Permissible temperature at temperature input exceeded.
Resistance value PTC > trigger value (standard 4.5kΩ)
61 Temperature 2, shutdown Error Permissible temperature at temperature input exceeded.
62 Temperature 2, short circuit Error A short circuit was detected at the temperature input.
63 Temperature 2, interruption Error An open circuit was detected at the temperature input.
64 Leakage 1, shutdown Error Permissible resistance value at the leakage input has been
exceeded or undershot.
65 Leakage 1, shutdown Error Contact at the leakage input has tripped.
66 Leakage 2, shutdown Error Permissible resistance value at the leakage input has been
exceeded or undershot.
67 Leakage 2, shutdown Error Contact at the leakage input has tripped.
