Bosch Rexroth OptiFeed-FS EcoDrive 03 FLP04VRS - C218 Feedback 2 Data Reading Error; C220 Feedback 1 Initializing Error

12-36 Diagnostic Message Descriptions ECODRIVE03-FL*-04VRS
DOK-ECODR3-FL*-04VRS**-FK01-EN-P
C218 Feedback 2 data reading error
If the measurement system to be initialized has an intrinsic memory, this
memory is read when the manual/automatic operating mode is switched
on. The C218 Feedback 2 data reading error message is generated if an
additional optional encoder (encoder 2) is present and being evaluated
(Parameter C004, Interface, feedback 2 is not set to "0"), and if an error
is discovered while reading the data.
Measurement systems with intrinsic data memory are :
• DSF/HSF/LSF and resolvers, as well as
• Measurement systems with the EnDat interface (from Heidenhain)
Cause:
1. Defective measurement system cable.
2. Defective measurement system.
Remedy:
For 1. Check the measurement system cable.
For 2. Replace measurement system.
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:
• an error reading the angle rectification data
• an error copying the angle rectification data
• interruption of communications with the encoder
• an assembly error regarding the position of an initialization track
• an error reading the analog signals of an initialization track
• an error in the pointer length for the analog signals of an initialization
track
• an invalid offset between the high- and low-resolution tracks
• Error in the measurement system micro-controller
Cause:
1. Defective motor feedback cable.
2. Motor encoder defective.
3. Defective measurement system interface
Remedy:
For 1. Check the motor feedback cable.
For 2. Replace the motor.
For 3. Replace the measurement system interface if it is a module, or
the complete drive controller.
