66 SYNCVELREL
This parameter indicates by how many percent the
slave drive can deviate from the velocity of the
master while attempting re-synchronization. For
example, during changes in SYNCPOSOFFS (54) or
at the start of synchronization or during the correc-
tion of deviation for marker evaluation. The follo-
wing is valid:
If the slave need to catch up it runs with the maxi-
mum speed allowed; this is either the speed set
with
VEL or the master velocity calculated with
MAVEL + MAVEL * SYNCVELREL/100
depending which of the two is less. (MAVEL is the
actual master velocity).
If the slave needs to slow down and wait for
the master it will run with at least the
following speed
MAVEL – MAVEL * SYNCVELREL/100.
That means, if SYNCVELREL is 50, for example,
the slave will not run slower than MAVEL/2.
