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

warning.
Status of mechanical brake
acknowledgment is not as
expected during brake open.
Open conditions of mechanical
brake cannot be fulfilled.
What to do
Check value of 43.08.
Check value of 43.09.
Let chopper cool down.
Check for excessive ambient
temperature.
Check for cooling fan failure.
Check for obstructions in the air flow.
Check the dimensioning and cooling of
the cabinet.
Check resistor overload protection
function settings (parameters
43.06...43.10).
Check minimum allowed resistor value
for the chopper being used.
Check that braking cycle meets allowed
limits.
Check that drive supply AC voltage is not
excessive.
Make sure that the I/O built in/extension
module is connected to the device.
Replace I/O module.
Check mechanical brake connection.
Check mechanical brake settings in
parameter group 44 Mechanical brake
control.
Check that acknowledgment signal
matches the actual status of the brake.
Check mechanical brake connection.
Check mechanical brake settings in
parameter group 44 Mechanical brake
control.
Check that acknowledgment signal
matches the actual status of brake.
Check mechanical brake settings in
parameter group 44 Mechanical brake
control.
Check that the acknowledgment signal (if
used) matches the actual status of the
brake.
