Siemens SINAMICS RAILCTRL, Function Manual

Page: 82 / 106

Acknowledge: IMMEDIATELY
Cause: An error has occurred during cyclic CU communication.
Fault cause:
1 (= 01 hex):
Technology Extension versions on the two Control Units do not match.
2 (= 02 hex):
Checksum error (CRC error).
3 (= 03 hex):
Data packages lost
4 (= 04 hex):
The communication is not running isochronously. It is not permissible to switch on the drive object.
CU connection:
0 (= 00 hex):
Communication error to the previous Control Unit.
1 (= 01 hex):
Communication error to the subsequent Control Unit.
Note regarding the alarm value:
The individual information is coded as follows in the alarm value (r2124):
yyxx hex: yy = error cause, xx = CU connection
Remedy: For fault cause = 1:
Update the Technology Extension so that an identical version is used on both sides.
For fault cause = 2:
Check the DRIVE-CLiQ connection for dirt/damage.
For fault cause = 3:
Check the DRIVE-CLiQ wiring for correct connection/contact.
For fault cause = 4:
Check the configuration of the isochronous communication of the two Control Units to the higher-level control. Do not
switch on the drive object as long as isochronous communication has not been established.
Note:
RAILCTRL: Controller for Segmented Linear Drives
Reaction upon A: NONE
Acknowl. upon A: NONE
F53165 RAILCTRL CU communication parameterization incomplete
Drive object: All objects
Message class: General drive fault (19)
Message value: CU connection: %1
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: Using p30490, CU communication was activated at a DRIVE-CLiQ socket. This is why it is necessary to set the coordinate
offset in p30492[0...1].
CU connection:
0 (= 00 hex):
Communication to the previous Control Unit incomplete.
1 (= 01 hex):
Communication to the subsequent Control Unit incomplete.
Note regarding the alarm value:
The incompletely configured CU connection is also displayed in alarm value (r2124).
