Error messages
E.Acc
ERROR! maximum
acceleration
24 Maximum acceleration exceeded
E.blc ERROR! Blockade 26 A blockade was recognized. Pn.85 Bit 4 is at error, no auto-reset.
E. br Error ! Brake control 56
Error: can occur at activated brake control (see chapter 6.9.5) if:
the load during the start is below the minimum load level (Pn.43) or
the missing of a motor phase was recognized.
the load is too high and the hardware current limit is reached.
E.buS Error ! Watchdog 18
Error: Adjusted monitoring time (Watchdog) of thecommunication
between operator and PC / operator and inverter has been exceeded.
E.Cdd Error ! calc. drive data 60 Error: During the automatic motor stator resistance measurement.
E.co1 Error ! counter overrun 1 54
Counter overflow encoder channel 1
E.co2 Error ! counter overrun 2 55
Counter overflow encoder channel 2
E.dOH Error ! drive overheat 9
Error: Overtemperature of motor PTC. Error can only be reset at
E.ndOH, if PTC is again low-resistance. Causes:
Resistance at terminals T1/T2 >1650 Ohm
Motor overloaded
Line breakage to the temperature sensor
E.dri Error ! driver relay 51
Error: Driver relay. Relay for driver voltage on power circuit has not
picked up even though control release was given.
E.EEP Error ! EEPROM defective 21
After reset the operation is again possible (without storage in the
EEPROM)
E. EF Error ! ERROR external fault 31
Is triggered, if a digital input is being programmed as external error
input and trips.
E.Flc ERROR! Flow control 27
The flow control is activated in Pn.91. No input and output for the
valve control is selected in Pn.92 and 93.
E.Enc1 Error ! Encoder 1 32 Cable breakage at the encoder. Encoder temperature is too high.
Speed is too high. Encoder signals are outside the specification.
Internal defect.
E.EnC2 ERROR! encoder 2 34
E.EncC Error ! Encoder change 35
Operation of a synchronous motor with intelligent interface:
• Encoder not connected at power-on
• Encoder was changed
This error can be reset by writing on Ec.00 and from version 4.2 via
hardware or bus-reset. The fault localization is described in Ec.37.
E.Hyb Error ! Encoder interface 52
Invalid encoder interface identifier.
E.HybC Error ! hybrid changed 59
The encoder interface identifier has changed and must be confirmed
via Ec.00 or Ec.10.
E.iEd Error ! input error detect 53
Hardware error at NPN-/PNP change-over or at start/stop
measurement.
E.iPH ERROR! Output phase 5 Phase loss detection at the output
E.InI Error ! MFC not booted 57 MFC not booted
further on next side
