Remarks:
m Bit 3 to 0: Synchronous operation
0000: Actual master axis in relative synchronized angle run
The set value for the slave axis is specified in this mode directly through a encoder in-
put. The axis is located in the position control.
When enabling the drive in the operating mode synchronous operation or switching to
this operating mode during active operation, the angle will be permanently positioned
between master and slave axis. This means that the master axis and slave axis will
have an angle relation to each other from this point on that is permanent but not de
-
fined. The existing angle relation will be lost in the event of a control block, a different
operating mode or a Stop command to the slave axis.
When the speed synchronization is ON (Mode bit 8 = 1), the angle relation will not be
specified until the synchronization has been established.
0010: Virtual master axis in relative synchronized angle
The set value for the slave axis is specified in this mode through Parameter Z145.10–
Virtual master speed set value. The axis is located in the position control.
A position set value for the virtual master axis is calculated in the drive from the speed
set value. The drive follows this virtual master axis synchronized.
This mechanism is purposeful when other axis are connected as slave axis. These
slave axis then receive the set value of the virtual master axis as input set value. Sub
-
sequently, all other axis then follow the same set value including the axis that calcu-
lates the virtual master axis itself.
The input set value of the virtual master axis can be routed through a ramp generator
(ramp function generator) or have a direct effect. Refer to the related explanations of
bit
12 of the mode.
m Bit 8: Activate speed synchronization on master axis
This bit activates the speed synchronization for the speed set value of the master axis
when activating the operating mode synchronous operation or following a Stop com
-
mand through the control word (Z108.1– bit 8 = 1)
Procedure of synchronization after activation:
– Automatic activation of the internal ramp generator using Parameters Z145.7– to
Z145.9–.
– The speed set value of the master axis defines the target speed for the ramp gener-
ator.
13 Real master axis: Setting of the set value source
0: The set value for synchronous operation is the actual value of the master
axis encoder
1: The set value for synchronous operation is the set value of the other axis
(possible only at double axis units)
