E.dOH ERROR drive overheat 9 Error: Overtemperature signal from motor temperature sensor.

Error can only be reset at E.ndOH, when sensor resistance

decreases. Causes:

• resistor at the terminals T1, T2 >1650 Ohm

• motor overloaded

• line breakage to the temperature sensor

E.nEd no ERROR detected 10 No defined error recognized (should not occur)

E.ndOH no ERROR drive overheat 11 No longer overtemperature of motor Temperature SENSOR,

SENSOR is again low-resistance.

E. PU ERROR power unit 12 Error: General power circuit fault

NO.PU power unit not ready 13 Power circuit not ready

E.PUIN ERROR power unit invalid 14 Error: Software version for power circuit and control card are

different. Error cannot be reset.

E.LSF ERROR load shunt fault 15 Error: charging relay does not close after the DC bus voltage

reaches its normal operating level. Occurs for a short time

during the switch-on phase, but must automatically be reset

immediately (after 10 sec's E.UP). If the error message re-

mains, the following causes may be applicable:

• load-shunt defective

• input voltage incorrect or too low

• high losses in the supply cable

• braking resistor incorrectly connected or damaged

• braking module defective

E. OL ERROR overload 16 Error: Overload error can only be reset at E.nOL, if OL-counter

has again reached 0%. Occurs, if an excessive load is applied

longer than the permissible time (see technical data). Causes:

• poor control adjustment (overshooting)

• mechanical fault or overload in the application

• inverter not correctly sized for application

• motor incorrectly wired

• encoder damaged

E.nOL no ERROR overload 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.

E.buS ERROR bus 18 Error: Adjusted time (Watchdog) of communication between

operator and communication bus has been exceeded.

E.OL2 ERROR overload 2 19 Error: Overload while running below 3 Hz. Can only be reset at

E.nOL2, if cool-down time has elapsed.

E.nOL2 no ERROR overload 2 20 No more overload, the cool-down time is terminated.

E.EEP E. EEPROM defective 21 Error: EEPROM defective. After reset the error is repeated.

(parameter values changed are erased in the EEPROM)
