Chain Configuration with Fast Link
Slave 2 could also send its control pos and rev data to Slave 3 (avoiding encoder noise):
 IPA 11144 Els Rev Dem dest = Pad 1 (ex.)
 IPA 11150 Els Pos Dem dest = Pad 2 (ex.)
 IPA 5730 = Pad 2
 IPA 5732 = Pad 1
5.4 Virtual master
The Virtual master function is used to simulate rotation of an encoder. This function lets you eliminate all
causes of interference and noise that would otherwise be transferred in links in normal connections to a
physical encoder as well as eliminate the phase shift phenomenon (phase delay of slave motor compared to
master based on control system cycle time and master speed).
When the Virtual master is used, the ELS application is loaded on all drives and all of them are slaves of the
virtual encoder generated by one of the drives in the system.
Data from the drive generating the Virtual master is transmitted to the other drives in the system via Fast Link.
The drive where Fast Link is generated reads the Virtual master data with a delay cycle equal to the time for
data transmission to the bus in order to align it to all other system drives.
To activate the Virtual master, set the MASTER REF menu: 11018 ELS Master sel = Virtual Enc.
A series of additional parameters and commands lets you control the number of pulses generated, as well as
the start, direction, accelerations and target speed of the virtual encoder. The generated speed profile is
trapezoidal.
Transmission of the virtual encoder data to the slaves in the chain passes through the ADV200 drive PAD
functions. PADs are general-use variables that are used for data exchange among the components of a Bus
system, and can therefore be compared to PLC variables. For more information, see “ADV200 Description of
functions and parameters list.”
A slave drive of a physical encoder CANNOT generate a virtual encoder for other slave drives.
