For synchronizing the setting must be at
least the same as the maximum velocity of
the master in order to be able to synchronize. For
position synchronizing it must even be higher so
that the slave can catch up lost position related to
the master. All velocity commands (VEL, CVEL) are
related to this value.

Setting of SyncPos option parameters: Home
Homing is not necessary in standard synchroniza-
tion applications and applications using an abso-
lute encoder.
When using an incremental encoder the controller
must be run to home after being switched on.
During this process the reference switch defines
the position at which 0 is located and how the VLT
functions during a home run: input depends on the
application.

SYNCFACTM and SYNCFACTS must be set accor-

encoder.
Example: Both encoders has 1024 ppr, master is
running 305 RPM and slave must run 1220 RPM.
SYNCFACTM =
305 and
SYNCFACTS =
1220.
Alternative:
SYNCFACTM = 1
SYNCFACTS = 4.

"AXIS":
SYNCMARKM (52) and SYNCMARKS (53)
Number of master marker pulses and number of
slave marker pulses.
SYNCMARKM and SYNCMARKS must be set
according to the ratio between the number of
marker signals from master and slave. A ratio of
1:1 means that each slave marker will be aligned
with each master marker. A ratio of 2:1 means that
each slave marker will be aligned with each
second master marker.
