Controlling the MOVITRAC
®
B frequency inverter (gateway)
Operating Behavior on EtherCAT
®
The first 3 process data words are exchanged with the first MOVITRAC
®
B unit on the
DFE24B gateway. They can be connected to the PLC program or written for manual
testing (see the following figure).
First, mark the process output data PO1. In the window that appears, choose the tab
page "Online". Click on the "Write" button. The "Set Value Dialog" window opens. Enter
your data in the field "Dec" or "Hex". Handle the PO2 process output data in the same
way.
The 3 process input and output data words are assigned and scaled in MOVITRAC
®
B
in the 87_ parameter group or defined via an IPOS
plus®
program.
For more information, refer to the MOVITRAC
®
B system manual and the "MOVITRAC
®
B Communication and Fieldbus Unit Profile" manual.
6.2.2 SBus timeout
If one or more drive inverters on the SBus can no longer be addressed by the DFE24B,
the gateway enters error code F11 System fault, in status word 1 of the corresponding
inverter. LED H1 (system fault) lights up. The fault is also displayed via diagnostics in-
terface X24. It is necessary to set the SBus timeout interval (P883) of the MOVITRAC
®
B system error to a value other than 0 for the inverter to stop. The timeout response is
set via parameter P836.
6.2.3 Unit error
The gateways detect a series of errors during the self test and respond by locking them-
selves. The exact error responses and remedies can be found in the list of errors. A
hardware defect causes error F111 system fault to be displayed on the fieldbus process
input data for status words 1 of all inverters. In this case, LED "H1" (system error) flashes
at regular intervals on the DFE24B. The exact error code is displayed in the status of the
gateway with MOVITOOLS
®
MotionStudio using diagnostics interface X24.
