A8A1 RO life warning
Cause
Motor current is too high.
The I/O built in/extension
module is not connected to the
device properly.
Calibration data is not stored in
the I/O module. Analog signals
are not working with full
accuracy.
Cyclical communication
between drive and fieldbus
adapter module A or between
PLC and fieldbus adapter
module A is lost.
Communication break in
embedded fieldbus (EFB)
communication.
Control panel or PC tool
selected as active control
location for drive has ceased
communicating.
The relay has changed states
more than the recommended
number of times.
0001 Relay output 1
0002 Relay output 2
0003 Relay output 3
Analog signal is beyond limits.
The relay has changed states
more than the recommended
number of times.
What to do
Check for overloaded motor
Adjust the parameters used for the motor
overload function. (35.51...35.53, 35.55,
35.56)
Make sure that the I/O built in/extension
module is connected to the device.
Replace I/O module.
Check status of fieldbus communication.
See user documentation of fieldbus
interface.
Check settings of parameter groups
Fieldbus adapter
settings, 52 FBA A data in
data out.
Check cable connections.
Check if communication master is able to
communicate.
Check the status of the fieldbus master
(online/offline/error etc.).
Check cable connections to the
EIA-485/X5 terminals 29, 30 and 31 on
the control unit.
Check PC tool or control panel
connection.
Check control panel connector.
Check mounting platform if being used.
Disconnect and reconnect the control
panel.
Replace the drive cooling fan.
Change the control board or stop using
the relay output.
Change the control board or stop using
relay output 1.
Change the control board or stop using
relay output 2.
Change the control board or stop using
relay output 3.
Check the signal level, input wiring, and
the defined limits.
3 – AI2 less minimum
4 – AI2 greater maximum
Change the control board or stop using
the relay output.
