C221 Feedback 2 Initializing Error; C223 Input Value For Max. Range Too High; C227 Modulo Range Error - Bosch Rexroth OptiFeed-FS EcoDrive 03 FLP04VRS Functional Description

ECODRIVE03-FL*-04VRS

C221 Feedback 2 initializing error

C223 Input value for max. range too high

C227 Modulo range error

DOK-ECODR3-FL*-04VRS**-FK01-EN-P
Several checks are performed during the initialization of an optional
encoder. 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
•
with DAG 1.2: error, external 24V set for SSI interface
Cause:
1. Defective opt. encoder cable
2. Defective encoder
3. Defective measurement system interface
Remedy:
For 1. Check opt. encoder cable.
For 2. Replace encoder.
For 3. Replace the measurement system interface (module).
Cause:
An internal position resolution was set which no longer ensures correct
commutation of the motor.
Remedy:
•
Check parameters and make corrections.
•
Check for correct firmware.
•
Turn off and then on again. If this does not solve the problem:
•
Replace the unit.
Cause:
The modulo value entered is larger than half of the position display range
of the drive.
Remedy:
Select a smaller modulo value, Parameter A105.
