commissioning of Lenze devices in the EtherCAT network.
6.3.1 Preparation / installation
)
Note!
Lenze devices without an external sync terminal input do not support DC
synchronisation.
Connect the sync terminal block of the EtherCAT communication module to the voltage
supply and the corresponding input terminal of the standard device (see
¶ 29 and the
documentation for the standard device).
6.3.2 DC configuration in the master
ƒ The use of the DC synchronisation is deactivated in the device description (
¶ 31) by
default.
ƒ Parameterise the DC synchronisation in the EtherCAT configuration software.
ƒ Specify the synchronisation cycle time in the master. It significantly complies with
the processing time of the master and slaves.
6.3.3 DC configuration in the standard device (slave)
ƒ In order to be able to use the DC synchronisation via EtherCAT in the standard
device, select the "AIF" sync source with standard device code C1120.
ƒ Set the cycle time of the standard device in milliseconds with code C1121.
ƒ Depending on the standard device, it may be required to also select a corresponding
operating mode and control interface for EtherCAT communication via code.
Information on this can be found in the documentation for the standard device.
