C218 Feedback 2 data reading error
The initialization of the measuring systems is done in the command
S-0-0128, C200 Communication phase 4 transition check. If the
measuring system to initialize has an intrinsic data memory, this memory
is read.
The error C218 Feedback 2 data reading error is generated, if an
additional optional encoder (encoder 2) is present and being evaluated
(P-0-0075 Feedback 2 type other than 0) and if an error is discovered
while reading the data.
Measuring systems with intrinsic data memory are :
• DSF/HSF/LSF and resolver, as well as
• measuring systems with Endat interface (from Heidenhain)
Cause:
1. Defective measurement system cable
2. Defective measurement system
Remedy for:
1. Check the measurement system cable.
2. Exchange the measurement system.

phase 4 transition check".
C220 Feedback 1 initializing error
A number of tests are performed when the motor encoder is initialized. An
error was detected during this process. This error may be:
• Error while reading the angle rectification data
• Error while copying the angle rectification data
• Interruption of communication with the encoder
• Assembly error with the position of an initialization track
• Error while reading the analog signal of an initialization track
• Error in the pointer length of the analog signal of an initialization track
• Invalid offset between the high and low resolution track
• Error in the measuring system micro-controller
Cause:
1. Defective motor feedback cable
2. Defective motor feedback
3. Defective measurement system interface
Remedy for:
1. Check the motor feedback cable.
2. Exchange the motor.
3. Exchange the measuring system interface, if it is a module, or the
complete drive controller.
