OVERVIEW
Thank you for using Inovance's MD800 series AC drives and SI-ECAT communication expansion card.
The SI-ECAT card is an EtherCAT fieldbus adapter card, which can be used in the ultra-high speed I/O network.
The protocol is applicable on the I/O layer.
This card features high efficiency, flexible topology, and easy operation. It is installed in the MD800 series AC
drive to increase the communication efficiency and implement the AC drive networking function, which
enables the AC drive to be a slave controlled by the field bus master station.
SI-ECAT accepts the fieldbus master station control. EtherCAT communication supports a minimum
synchronization cycle of 500µs. The internal bus between SI-ECAT, rectifier and inverter units have a
communication cycle of 40ms.
NOTE
The SI-ECAT supports the
CiA402 Velocity and Cyclic Synchronous Velocity (CSV)
modes which are
suitable for the MD800 open loop (sensorless) operation. MD800 does not support encoder feedback.
This manual requires that the corresponding SI-ECAT card software version is 1.08 or above (after the card is
installed and powered on, the function code can be checked in the rectifier FD
‑
91), the associated device
description XML file is named "MD800_9Axis_EtherCAT_XML_Vn.nn.xml" (n.nn is the version number, use
version above V0.16).
CiA402 Velocity and Cyclic Synchronous Velocity (CSV) modes require the below software version:
•
Rectifier software version:
U05.00 and above (checked by parameter: F0-02 = 05.00)
•
Inverter software version:
U80.03 and above (checked by parameter: F7-10 = 80.03)
•
SI-ECAT card:
V01.15 and above (checked by rectifier parameter: FD-91 = 01.15)
Before using the product, read this user guide thoroughly.
