301
Number
Cause
Remedy
F01034 Switching over units: Calculation of
the parameter values after
reference value change
unsuccessful
Select the value of the reference parameter so that the parameters
involved can be calculated in the per unit notation (p0304, p0305, p0310,
p0596, p2000, p2001, p2002, p2003, r2004).
A01053
System overload measured
The maximum computing power of the control unit was exceeded. The
following measures reduce the load on the control unit:
Use only one data record (CDS and DDS)
Only use the safety features of the basic functions
Deactivate the technology controller
Use the simple ramp-function generator rather than the extended
ramp-function generator
Do not use any free function components
Reduce the sampling time of the free function blocks
F01054 System limit exceeded
F01122 Frequency at the probe input too
high
Reduce the frequency of the pulses at the probe input.
A01590
Motor maintenance interval lapsed
Carry out maintenance and reset the maintenance interval (p0651).
A01900 PROFIBUS: Configuration
telegram faulty
Explanation: A PROFIBUS master is attempting to establish a connection
with a faulty configuration telegram.
Check the bus configuration on the master and slave side.
A01910
F01910
Setpoint timeout The alarm is generated when p2040 0 ms and one of the following
causes is present:
The bus connection is interrupted
The Modbus master is switched off
Communications error (CRC, parity bit, logical error)
An excessively low value for the fieldbus monitoring time (p2040)
A01920 PROFIBUS: Cyclic connection
interrupt
Explanation: The cyclic connection to PROFIBUS master is interrupted.
Establish the PROFIBUS connection and activate the PROFIBUS master
with cyclic operation.
F03505 Analog input, wire break Check the wiring for interruptions.
Check the level of the injected signal.
The input current measured by the analog input can be read out in r0752.
A03520
Temperature sensor fault
Check that the sensor is connected correctly.
A05000
A05001
A05002
A05004
A05006
Power Module overtemperature Check the following:
- Is the ambient temperature within the defined limit values?
- Are the load conditions and duty cycle configured accordingly?
- Has the cooling failed?
F06310 Supply voltage (p0210) incorrectly
set
Check the set supply voltage and if required change (p0210).
Check the line voltage.
F07011 Motor overtemperature Reduce the motor load.
Check the ambient temperature.
Check the wiring and connection of the sensor.
