set the resolution
of the encoder.
-
In
32-44 Enc.1 node ID
set the CAN ID of the
encoder.
-
In
32-45 Enc.1 CAN guard
activate or deactivate
the guarding.

3.4.4 Setting of Velocity Parameters
Define
32-80 Maximum Velocity (Encoder)
, the
Maximum
Velocity
of the shaft where the encoder is mounted in RPM.
32-8* Velocity & Acceleration
Default
32-80 Maximum Velocity (Encoder)
1500
32-81 Shortest Ramp
1.000
NOTE
For synchronizing application the setting of the follower
drive 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
follower drive can catch up lost position related to the
master. All velocity commands (VEL, CVEL) are related to
this value.
Define
32-81 Shortest Ramp
. That is the time from 0 to
maximum velocity and from maximum velocity to 0. All
acceleration and deceleration commands (ACC, DEC) are
related to this value.
3.4.5 Setting of Home Parameters
Homing is not necessary in standard synchronization
applications and applications using an absolute 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 AutomationDrive functions
during a home run: input depends on the application.
Define
33-03 Velocity of Home Motion
: Home speed is
entered in % relative to the maximum speed of the
frequency converter.

3.4.6 Setting of Synchronization Parameters
The following parameters are only relevant for synchro-
nizing applications:
•
33-10 Sync Factor Master
•
33-11 Sync Factor Slave
The
Synchronizing Factors Master
and
Slave
must be set
according to the gear ratio between master and slave
encoder.
Example:
Both encoders have 1024 PPR, master is
running 305 RPM and slave must run 1220
RPM.
33-10 Sync Factor Master
= 305 and
33-11 Sync Factor Slave
= 1220
Alternative:
33-10 Sync Factor Master
= 1
33-11 Sync Factor Slave
= 4
The following parameters are only relevant when using
synchronizing with marker correction (SYNCM):
•
33-15 Marker Number for Master
•
33-16 Marker Number for Slave
Marker Number for Master
and
Slave
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.
