4. Error messages
Errors cause the immediate deactivation of the modulation and the generation of corresponding error messages (see
table). Before carrying out a restart remove the the error first and then actuate reset.
Display Bus Meaning
E.OP 1 Error Overpotential - The DC-link voltage has exceeded the permissible value.
E.UP 2 Error Underpotential - The DC-link voltage has fallen below the permissible value.
E.OC 4 Error Overcurrent - The output current has exceeded the permissible value.
E.OH 8 Error Overheat - The temperature monitoring of the frequency inverter has tripped and the
prewarning time (10s) is expired.
E.dOH 9 Error Drive Overheat - The temperature monitoring of the motor has tripped and the prewarning time
(Pn.16) is expired.
E.nOH 36 Error no Overheat - Overtemperature error no longer exists, the error messages (E.OH / E.dOH)
can be reset and the frequency inverter restarted.
E.OL 16 Error Overload - The operation of the frequency inverter in the overload range has exceeded
the permissible time (see overload characteristic in the Instruction Manual
Part 2).
E.OL2 53 Error Overload 2 - Same meaning as E.OL, but occurs only in the lower frequency range (<3 Hz)
(see overload characteristic in the Instruction Manual Part 2).
E.nOL 17 Error no Overload - After the cooling down phase the overload error (E.OL or E.OL2) no longer
exists, the error message can be reset and the frequency inverter restarted.
E.buS 18 Error Bus - The adjusted Watchdog-time (parameter ud.8) of the serial communication
has been exceeded (only at parameter Pn.23 = 0).
E.LSF 15 Error Load Shunt - After switching on the frequency inverter the input voltage is too low or the
load shunt relay is not switching (monitoring with load shunt relay not
available for all unit sizes).
E.EF 31 Error External Fault - The signal for an external error is given to a programmable digital input (only
at parameter Pn.20 = 0).
E.SEt 39 Error Set - Set selection error: selected parameter set is locked (see parameter Fr.3)
E.PrF 46 Error Prohibited - At setpoint rotation forward terminal F (rotation release forward) is not active
(only at parameter Pn.24 = 0).
E.Prr 47 Error Prohibited - At setpoint rotation reverse terminal R (rotation release reverse) is not active
(only at parameter Pn.24 = 0).
E.dSP 51 Error Digital Signal - Processor - error
Processor
E.Hyb 52 Error Hybrid - Control card error: carry out Power-on reset; if the error message continues
to show, the error can be removed only in the factory.
E.PuC 49 Error Power Unit - Control card error: carry out Power-on reset; if the error message continues
to show, the error can be removed only in the factory.
E.SLF 110 Error Software Limit - Selection of setpoint position outside the adjusted software limit at rotation
forward (also see parameter Pc.4...Pc.6 positioning module)
E.SLr 111 Error Software Limit - Selection of setpoint position outside the adjusted software limit at rotation
reverse (also see parameter Pc.7...Pc.9 positioning module)
