F228 Excessive deviation
When the position loop is closed, the drive monitors whether it is able to
follow the specified command value. This is done by calculating a model
position value in the drive and comparing that value with the actual
feedback value. If the difference between theoretical and actual position
value permanently exceeds the value of the S-0-0159, Monitoring
window parameter, the drive obviously cannot follow the given
command value. Then this error is generated.
Cause:
1. The drive’s acceleration capacity has been exceeded.
2. The axis is blocked.
3. Incorrect parameter values set in the drive parameters.
4. Incorrect parameter values in S-0-0159, Monitoring window.
Remedy:
Ref. 1. Check the S-0-0092, Bipolar torque/force limit value
parameter and set it to the maximum permissible value of the
application. Reduce the specified acceleration value from the
controller (see controller Manual).
Ref. 2. Check the mechanical system and eliminate jamming of the axis.
Ref. 3. Check the drive parameters (control loop tuning).
Ref. 4. Set the parameter values of S-0-0159, Monitoring window.

F229 Encoder 1 failure: quadrant error
With wrong signals in the encoder evaluation, a hardware error has been
discovered in the encoder interface 1 being used.
Cause:
1. Defective encoder cable
2. Disruptive electro-magnetic interference on the encoder cable
3. Defective encoder interface
4. Defective drive controller
Remedy:
For 1. Exchange the encoder cable.
For 2. Keep the encoder cable well away from the power cables.
For 3. Exchange the encoder interface.
For 4. Exchange the drive controller.
F230 Max. signal frequency of encoder 1 exceeded
The signal frequency of the encoder 1 (motor encoder) is checked
whether the allowed max. frequency of the encoder interface is
exceeded.
If the frequency is higher than allowed, the error F230, Max. signal
frequency of encoder 1 exceeded is generated. The position status of
the encoder 1 is cleared to 0.
