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 the theoretical and actual
position values continually exceeds the value in Parameter A115,
Monitoring, the drive obviously cannot comply with the given command
value. This error is then generated.
Cause:
1. The drive’s acceleration capacity has been exceeded.
2. The axis is locked.
3. Incorrect parameter values set in the drive parameters.
4. Parameter A115, Monitoring set incorrectly.
Remedy:
For 1. Check program to see whether a value that is too low has been
entered in a MOM command.
For 2. Check the mechanical system and eliminate jamming of the axis.
For 3. Check the drive parameters (control loop settings).
For 4. Set Parameter A115, Monitoring.

F229 Encoder 1 failure: Quadrant error
On the basis of faulty signals detected during the encoder evaluation, a
hardware error has been discovered in the interface being used for
encoder 1.
Cause:
1. Defective encoder cable
2. Electromagnetic interference on the encoder cable
3. Defective encoder interface
4. Defective drive controller
Remedy:
For 1. Replace the encoder cable.
For 2. Keep the encoder cable well away from power cables. Use
shielded motor and encoder cables.
For 3. Replace the encoder interface.
For 4. Replace the drive controller.
F230 Max. signal frequency of encoder 1 exceeded
The signal frequency of encoder 1 (motor encoder) is checked to see
whether the max. permissible frequency of the encoder interface has
been exceeded.
If the frequency is higher than allowed, error F230, Max. signal
frequency of encoder 1 exceeded is generated. The “homed” output in
Parameter C010 is turned off.
