Operating Instructions, 04/2018, FW V4.9 SP10, A5E34262100B AF
Number Cause
Remedy
F01662
CU hardware fault
Switch CU off and on again, upgrade firmware or contact technical sup-
port.
A01666
Static 1 signal at the F-DI for safe
acknowledgment
Set fail-safe digital input F-DI to a logical 0 signal.
A01698
Commissioning mode active for
safety functions
This message is withdrawn after the Safety commissioning has ended.
A01699
Switch-off signal path test required After the next time that the "STO" function is deselected, the message is
withdrawn and the monitoring time is reset.
A01900
PROFIBUS: Configuration tele-
gram 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 connection to the signal source for interrupts.
Check the level of the signal supplied.
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
parameterized
Check the parameterized supply voltage and if required change (p0210).
Check the line voltage.
F07011
Motor overtemperature
Reduce the motor load.
Check ambient temperature.
Check the wiring and connection of the sensor.
A07012
I2t Motor Module overtemperature Check and if necessary reduce the motor load.
Check the motor's ambient temperature.
Check thermal time constant p0611.
Check overtemperature fault threshold p0605.
A07015
Motor temperature sensor alarm
Check that the sensor is connected correctly.
Check the parameter assignment (p0601).
F07016
Motor temperature sensor fault
Make sure that the sensor is connected correctly.
Check the parameterization (p0601).
Deactivate the temperature sensor fault (p0607 = 0).
F07086
F07088
Unit switchover: Parameter limit
violation
Check the adapted parameter values and if required correct.
