m There are two additional inputs (Z145.15– and Z145.16–) besides the main set value
Z145.10– or the master axis position, if the master axis is virtual or real.
m The master axis position of the real master axis can be shifted with Z145.18– Angle of
master axis offset for the slave axis.
m Check whether encoder of the master axis is switched on at real master axis.
m Selection of the set value source with real master axis
The set value for the synchronous operation can be selected via Z145.2– Mode bit 13
only at double axis units. In addition to the position actual value the set value of the
master axis is possible.
Using of the set value of the master axis:
Depending on the drive state and the active operating mode at the master axis, their
position set value (
Z18.58– and Z18.59–, if position controlled operating mode is ac-
tive) or their speed set value total (Z18.21–, if speed controlled operating mode is ac-
tive) or the position actual value of the master axis encoder (when drive is inhibited or
operating mode without active speed controller) is used.
If the master axis operates in a speed controlled operating mode (speed control or
speed set value 1) and their speed set value is used as master set value, an absolute
angle relation is not more assured.
Notes regarding the operation of an actual master axis in relative synchronized
angle:
m with single axis units
The following encoder assignment must occur:
– The motor encoder of the slave axis must be connected to encoder input 1.
– The master encoder must be connected to encoder input 2.
– The slave axis (parameter set axis 1) is operated in operating mode "Synchronous
operation" (
Z109.1– = -5).
m with double axis units
The following encoder assignment must occur:
– Selection of the master axis, e.g. axis 1  Slave axis is then axis 2 
 Position actual value of the motor encoder of axis 1 = Position set value for axis 2
– The operating mode setting for the master axis depends on the application, e.g. "Po-
sition Target Specification" (Z109.1– = 1).
– The operating mode of the slave axis must be set to "Synchronous operation"
(
Z109.1– = -5).
