Value Meaning
8 Error: Overtemperature of power module. Error can only be
reset at E.nOH. Causes:
• insufficient air flow at the heat sink (soiled)
• ambient temperature too high
• ventilator clogged
30 Electronic motor protective relay has tripped.
6 Error: Overheating in the interior: error can only be reset at
E.nOHI, if the interior temperature has dropped by at least
3°C
16 Error: Overload error can only be reset at E.nOL, if OL-
counter reaches 0% again.
Occurs, if an excessive load is applied longer than for the
permissible time (see technical data). Causes:
• poor control adjustment (overshooting)
• mechanical fault or overload in the application
• inverter not correctly dimensioned
• motor wrongly wired
• encoder damaged
19 Occurs if the standstill constant current is exceeded (see
technical data and overload characteristics). The error can
only be reset if the cooling time has elapsed and E.nOL2 is
displayed.
1 Voltage in the DC-link circuit too high.
Occurs if the DC-link circuit voltage exceeds the permissible
value. Causes:
• poor controller adjustment (overshooting)
• input voltage too high
• interference voltages at the input
• deceleration ramp too short
• braking resistor defective or too small
58 Real speed is bigger than the max. Output speed.
33 Error in the power factor control
46 The drive has driven onto the right limit switch. Programmed
response "Error, restart after reset" (see chapter 6.7
"Response to errors or warning messages").
47 The drive has driven onto the left limit switch. Programmed
response "Error, restart after reset" (see chapter 6.7
"Response to errors or warning messages").
12 Error: General power circuit fault
49 Error: During the initialization the power circuit could not be
recognized or was identified as invalid.
50 Error: Power circuit identification was changed; with a valid
power circuit this error can be reset by writing to SY.3. If the
value displayed in SY.3 is written, only the power-circuit
dependent parameters are reinitialized. If any other value is
written, then the default set is loaded. On some systems
after writing Sy.3 a Power-On-Reset is necessary.
22 Error: Parameter value could not be written to the power
circuit. Acknowledgement from PC <> OK
