Operating Instructions

Number Cause Remedy
A01590 Motor maintenance interval elapsed Carry out maintenance and reset the maintenance interval (p0651).
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
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 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 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 ambient temperature.
Check the wiring and connection of the sensor.
A07012 I2t motor model overtemperature Check and if necessary reduce the motor load.
Check the motor's ambient temperature.
Check the 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 motor temperature sensor fault evaluation (p0607 = 0).
