F01650
Acceptance test required
Carry out an acceptance test and create test certificate.
Switch off the Control Unit and switch on again.
F01659
Write task for parameter rejected Cause: The inverter should be reset to the factory setting. However, it is not
permissible to reset the safety functions as the safety functions are currently
enabled.
Remedy with operator panel:
p0010 = 30
Parameter reset
p9761 = …
Enter password for the safety functions.
p0970 = 5
Reset start safety parameter.
The inverter sets p0970 = 5 once it has reset the pa‐
rameters.
Then reset the inverter to the factory setting again.
F01662
Error, internal communications
● Check the electrical cabinet design and cable routing for EMC compliance.
● Check whether an impermissible voltage is connected at one of the digital
outputs.
● Check whether a digital output is loaded with an impermissible current.
If the checks are unsuccessful:
● Switch off the inverter power supply and switch it on again
● Upgrade the firmware
● Contact technical support
A01666
Static 1 signal at the F-DI for safe
acknowledgement
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This message is withdrawn after the Safety commissioning has ended.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 re‐
quired
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withdrawn and the monitoring time is reset.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
Fieldbus SS 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 in‐
terrupt
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.
