List Manual, 09/2017, A5E33842890
F07754
Drive: Incorrect shutoff valve configuration
Message class:
Error in the parameterization / configuration / commissioning procedure (18)
Reaction:
OFF2
Acknowledge:
IMMEDIATELY (POWER ON)
Cause:
An incorrect shutoff valve configuration was detected.
Fault value (r0949, interpret decimal):
100:
Enable Safety Integrated (p9601/p9801), but p0218.0 = 0 (shutoff valve not available).
101:
The manipulated variable inhibit time is set less than the wait time to evaluate the feedback signal contacts when
switching on the shutoff valve (p0230 < p9625[0]/p9825[0]).
102:
The manipulated variable inhibit time is set less than the wait time to evaluate the feedback signal contacts when
switching off the shutoff valve (p0230 < p9625[1]/p9825[1]).
Remedy:
For fault value = 100:
Check the enable of Safety Integrated and the shutoff valve (p9601/p9801, p0218.0).
For fault value = 101:
Set the manipulated variable inhibit time higher than the wait time to evaluate the feedback signal contacts when
switching on the shutoff valve (p0230 > p9625[0]/p9825[0]).
For fault value = 102:
Set the manipulated variable inhibit time higher than the wait time to evaluate the feedback signal contacts when
switching off the shutoff valve (p0230 > p9625[1]/p9825[1]).

F07800
Drive: No power unit present
Message class:
Error in the parameterization / configuration / commissioning procedure (18)
Reaction:
NONE
Acknowledge:
IMMEDIATELY
Cause:
The power unit parameters cannot be read or no parameters are stored in the power unit.
Note:
This fault also occurs if an incorrect topology was selected in the commissioning software and this parameterization
is then downloaded to the Control Unit.
See also: r0200 (Power unit code number actual)
Remedy:
- carry out a POWER ON (switch-off/switch-on) for all components.
- check the power unit and replace if necessary.
- check the Control Unit, and if required replace it.
- after correcting the topology, the parameters must be again downloaded using the commissioning software.
F07801
Drive: Motor overcurrent
Message class:
Motor overload (8)
Reaction:
OFF2 (NONE, OFF1, OFF3)
Acknowledge:
IMMEDIATELY
Cause:
The permissible motor limit current was exceeded.
- effective current limit set too low.
- current controller not correctly set.
- U/f operation: Up ramp was set too short or the load is too high.
- U/f operation: Short-circuit in the motor cable or ground fault.
- U/f operation: Motor current does not match current of power unit.
- Switch to rotating motor without flying restart function (p1200).
Note:
Limit current = 2 x minimum (p0640, 4 x p0305 x p0306) >= 2 x p0305 x p0306
Remedy:
- check the current limits (p0640).
- vector control: Check the current controller (p1715, p1717).
- U/f control: Check the current limiting controller (p1340 ... p1346).
- increase the up ramp (p1120) or reduce the load.
- check the motor and motor cables for short-circuit and ground fault.
