13.6.6.1 UDT 886 - VMC_ConfigInverterEC_REF - inverter drive EtherCAT Data structure axis configuration
This is a user-defined data structure that contains information about the configuration
data. The UDT is specially adapted to the use of an inverter drive, which is connected via
EtherCAT.
13.6.6.2 FB 886 - VMC_KernelInverter_EC - inverter drive EtherCAT kernel
This block converts the drive commands for an inverter drive via EtherCAT and communi-
cates with the drive. For each inverter drive, an instance of this FB is to be cyclically
called.
Please note that this module calls the SFB 238 internally.
In the SPEED7 Studio, this module is automatically inserted into your
project.
In Siemens SIMATIC Manager, you have to copy the SFB 238 from the
Motion Control Library into your project.
Parameter Declaration Data type Description
Init INPUT BOOL The block is internally reset with an edge 0-1. Existing motion
commands are aborted and the block is initialized.
Config IN_OUT UDT 886 Data structure for transferring axis-dependent configuration
data to the AxisKernel.
Axis IN_OUT UDT 860 Data structure for transferring axis-dependent information to
the AxisKernel and PLCopen blocks.
13.6.6.3 FB 887 - VMC_InitInverter_EC - inverter drive EtherCAT initialization
This block is used to configure the axis. The block is specially adapted to the use of an
inverter drive, which is connected via EtherCAT.
Parameter Declaration Data type Description
Config IN_OUT UDT 886 Data structure for transferring axis-dependent configura-
tion data to the AxisKernel.
Axis IN_OUT UDT 860 Data structure for transferring axis-dependent information
to the AxisKernel and PLCopen blocks.
Enable INPUT BOOL Release of initialization
LogicalAddress INPUT INT Start address of the PDO input data
