17 No more overload, OL-counter has reached 0%; after the
error E. OL a cooling phase must elapse. This message
appears upon completion of the cooling phase. The error can
be reset. The inverter must remain switched on during the
cooling phase.
20 The cooling time has elapsed. The error can be reset.
4 Error: Overcurrent
Occurs, if the specified peak current is exceeded. Causes:
• acceleration ramps too short
• the load is too big at turned off acceleration stop and turned
off constant current limit
• short-circuit at the output
• ground fault
• deceleration ramp too short
• motor cable too long
• EMC
• DC brake at high ratings active (see 6.9.3)
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.
