REXROTH VisualMotion 9 - 403 System Error See Ext. Diag; 405 Phase %D: Drive DID Not Respond; 407 Drive %D Phase 3 Switch Error

3-16 Monitoring and Diagnostics VisualMotion 9 Troubleshooting Guide
DOK-VISMOT-VM*-09VRS**-WA02-EN-P
403 System Error see ext. diag.
Cause:
A communication problem has occurred in the SERCOS ring. The
extended diagnostic displayed is, “Dxx: Multiplex AT Error,” where xx is
the drive number. Extended diagnostics can be viewed by selecting
Diagnostics ⇒
⇒⇒
⇒ System in VisualMotion Toolkit.
Remedy:
Recycle system power. If recycling power does not resolve the error,
contact Bosch Rexroth service for assistance.
405 Phase %d: Drive did not respond
Cause:
A time-out in the SERCOS ring occurred when the control did not receive
a response from the drive during Phase %d (where %d = phase number)
initialization. The control sent out a signal to the drive, but the drive did not
respond. This distinguishes a communication error from an actual phase
switch error.
Remedy:
Check the fiber optic connections, the addresses set on the drives, and
the drive firmware versions.
407 Drive %d Phase 3 Switch Error
Cause:
The SERCOS phase 3 switch command failed for drive %d (where %d =
drive number). This usually indicates that configuration parameters for the
drive are invalid or have not been saved. This message is displayed
when an error occurs while the drive is switching from phase 2 to phase
3.
Note: Do not clear the error or switch to parameter mode before
viewing a list of invalid parameters. Doing so will clear any
chance of viewing invalid parameters.
Remedy:
1. View drive diagnostic under Commission ⇒
⇒⇒
⇒ Drive Overview. If the
drive status indicates parameters are invalid or lost, display the Phase
2 error parameter list for Drive %d (Step 2.)
2. To view phase 3 switch errors for the specific drive, select Data ⇒
⇒⇒
⇒
Parameters, select the appropriate drive and double click on
SERCOS parameter S-0-0021. This parameter will list all parameters
that are outside of their allowable ranges. Once the list is displayed,
switch to parameter mode and change the invalid parameters or
download a valid parameter file to the drive.
3. If the drive is not communicating, check the connections and the
addresses. If drive parameters were just downloaded, switch back
into parameter mode to reinitialize the interface.
