Number Cause Remedy
F01650 Acceptance test required Carry out an acceptance test and create test certicate.
Switch o the Control Unit and switch on again.
F01659 Write task for parameter rejected Cause: The converter 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 converter sets p0970=5 once it has reset the pa‐
rameters.
Then reset the converter 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 o the converter power supply and switch it on again
• Upgrade the rmware
• Contact technical support
A01666 Static 1 signal at the F-DI for safe
acknowledgment
Set failsafe 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This message is withdrawn after the Safety commissioning has ended.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-o signal path test re‐
quired
After the next time that the "STO" function is deselected, the message is with‐
drawn and the monitoring time is reset.
A01900 PROFIBUS: Conguration tele‐
gram faulty
Explanation: A PROFIBUS master is attempting to establish a connection with
a faulty conguration telegram.
Check the bus conguration on the master and device 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 o
• Communications error (CRC, parity bit, logical error)
An excessively low value for the eldbus 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.
