MCO 305 Design Guide
Function
Termination resistors can be switched on or off for
encoder 1.
Select Off [0] if high input impedance is required
when:
– One encoder is connected to multiple MCO 305
– The virtual master output of one MCO 305 is
connected to multiple MCO 305.
Select On [1] when the encoder is only connected
to this MCO 305.
See MCO 305 Operating Instructions for wiring
diagram.

Option
No soft changing
Encoder soft changing enable
Soft zero setting enable
Encoder soft changing and soft zero
enable
Function
Configuration of master position evaluation after a
change of encoder source.
Soft encoder changing is useful if encoders should
be switched while running. If this is done without
using this parameter, then setting the new encoder
will typically cause a position error, because the
encoder values are not the same.
Select No soft changing [0] to switch directly to the
position data of the new master source.
Select Encoder soft changing [1], then it does not
switch entirely to the value of the new encoder, but
it keeps the old value and just adds the differences
from the new encoder. This makes it possible to
change encoders "on the run".
Select Soft zero setting [2], if the encoder is used
by another axis or for some other purpose and you
don't want to really change the encoder value
when you use a DEFMORIGIN. If soft zero setting is
on, then you can use a DEFMORIGIN and the new
reported actual position is zero afterwards.
However, the encoder still has its old value (i.e. the
value you can see if you read it by using the
SYSVAR 0x0122022A or similar).
Selection Encoder soft changing and soft zero [3]
gives possibility for bump less changing of master
default setting
