Parameterization via EtherCAT
®
Operating Behavior in Connection with EtherCAT
®
LED of FSE24B indicates that no new user data is being received. At the same time,
FSE24B interrupts the process data communication with MOVITRAC
®
B, which means
that after 20 ms, the SBus timeout response (P836) set in MOVITRAC
®
B is triggered.
If the FSE24B communication option can no longer address a MOVITRAC
®
B unit, it
sends the error code F111 System error on status word 1 (if set in parameter group 87_)
to the EtherCAT
®
master. SYS-F LED (system error) is lit.
The status of the EtherCAT
®
connection, the assigned EtherCAT
®
address and other
status information is displayed in parameter group 09_ (bus diagnostics) (with
MOVITRAC
®
firmware 18225632.11 and higher).
6.1.3 Unit error
The FSE24B communication option detect a series of errors and locks subsequently. All
status LEDs are off.
6.2 Parameterization via EtherCAT
®
The SDO services READ and WRITE, which are common in CoE (CAN application pro-
tocol over EtherCAT
®
), provide access to the drive parameter in EtherCAT
®
.
6.2.1 SDO services READ and WRITE
The user interface is displayed differently depending on the EtherCAT
®
master or con-
figuration environment. In each case, however, the following data is required for execut-
ing the SDO command.
For the SDO services READ and WRITE, other flags and parameters might be neces-
sary:
• For activating the function
• For in-progress message or error message
• For timeout monitoring
• For reporting errors during the execution
SDO-READ Description
Slave address (16 bit) EtherCAT
®
address of the inverter from which data is to be read.
Index (16 bit)
Subindex (8 bit) Address in the object dictionary from which the data is to be read.
Data
Data length Structure for storing the received data and its length.
SDO-WRITE Description
Slave address (16 bit) EtherCAT
®
address of the inverter to which data is to be written.
Index (16 bit)
Subindex (8 bit) Address in the object dictionary to which the data is to be written.
Data
Data length Structure in which the data to be written is stored.
