Els - gefran ADV200-HC Instruction Manual

26.11 ELS

This menu let you set the electric shaft function.
Electric Shaft (ELS) configuration allows a group of drives (maximum of 4) to work with a position limit.
All the participants are Slave elements of a Virtual Master. All of the Slave have the option to follow/not follow
the Virtual Master position.
The Virtual Master is generated in an ADV200 defined as "Virtual Master".
The Virtual Master transmits commands and handshake between regulator and drives via bi-directional Fast
Link.
You have to install the Fast Link card and an encoder interface on all of the drives for the Electric Shaft function.
The motors must have encoders.
The system is divided into 3 blocks (see ELS Control figure):

Command

Virtual Master Management

Follower Regulator
"Command" Block
Receives movement commands (FWD and REV) and the speed reference (from digital or analog input).
In Electric Shaft function (Follower command activated), the "Command" block is active only on the drive
defined as "Virtual Master" (for example, "H&C SERVICE \ Movement type" = Trolley-ELS-VM).
"Virtual Master" Block
Enabled only on the drive defined as "Virtual Master" (for example, "H&C SERVICE \ Movement type" = Trolley-
ELS-VM).
The speed/position reference generated by the Virtual Master is acquired by all of the drives where the Follower
command has been activated, including the drive set as "Virtual Master".
The "Virtual Master" block:

Generates a position and a speed with linear ramp based on set speed reference.

Manages brake opening.
