Faults and Alarms
List of faults and alarms
Reaction upon F:
OFF2
Acknowledge
IMMEDIATELY
upon F:
F07422
Drive: Speed controller reference model natural frequency > Shannon frequency
Reaction:
NONE (OFF1, OFF2, OFF3)
Acknowledge:
IMMEDIATELY (power on)
Cause:
The natural filter frequency of the PT2 element for the reference model (p1433) is greater than the Shannon fre-
quency.
The Shannon frequency is calculated according to the following formula: 0.5 / p0115[0]
Remedy:
- reduce the natural frequency of PT2 element for reference model (p1433).
- reduce the speed controller sampling time (p0115[1]).
F07500
Drive: Power module data set PDS not configured
Reaction:
NONE
Acknowledge:
IMMEDIATELY
Cause:
Only for controlled line supply infeed/regenerative feedback units:
The power module data set was not configured - this means that a data set number was not entered into the drive
data set.
Fault value (r0949, decimal):
Drive data set number of p0185.
Remedy:
The index of the power module data set associated with the drive data set should be entered into p0185.
F07501
Drive: Motor data set MDS not configured
Reaction:
NONE
Acknowledge:
IMMEDIATELY
Cause:
Only for power modules:
The motor data set was not configured - this means that a data set number was not entered into the associated drive
data set.
Fault value (r0949, decimal):
The fault value includes the drive data set number of p0186.
Remedy:
The index of the motor data set associated with the drive data set should be entered into p0186.
F07502
Drive: Encoder data set EDS not configured
Reaction:
NONE
Acknowledge:
IMMEDIATELY
Cause:
Only for power modules:
The encoder data set was not configured - this means that a data set number was not entered into the associated
drive data set.
Fault value (r0949, decimal):
The fault value includes the drive data set number of p0187, p0188 and p0189.
The fault value is increased by 100 * encoder number (e.g. for p0189: Fault value 3xx with xx = data set number).
Remedy:
The index of the encoder data set associated with the drive data set should be entered into p0187 (1st encoder),
p0188 (2nd encoder) and p0189 (3rd encoder).
F07510
Drive: Identical encoder in same drive data set (DDS)
Reaction:
NONE
Acknowledge:
IMMEDIATELY
Cause:
More than one encoder with identical component number is assigned to a single drive data set. In one drive data set,
it is not permissible that identical encoders are operated together.
Fault value (r0949, decimal):
Drive data set + 100*first identical encoder + 1000*second identical encoder.
See also: p0141, p0187, p0188, p0189
Remedy:
Different encoders are always assigned to one drive data set.
