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 axes 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.
– The speed actual value of the slave axis, under consideration of the inverse trans-
mission factor, corresponds with the start speed for the ramp generator. This en-
ables the activation of a moved slave axis on the fly.
– Synchronicity is considered to be established when the slave axis enters the
Z145.6– Synchronization velocity window for the first time around the speed set val-
ue of the master axis. From this point, the controller will independently switch from
the internal ramp generator to the set value of the master axis.
– If the master axis changes its speed during synchronization in progress, the target
speed for the ramp generator will be adjusted accordingly.
If the new target speed slows down, braking occurs with a deceleration value Z145.8–
to the new value.
In the case of the S-curve, the current acceleration value must first be reduced through
the jerk value setting Z145.9–, which means the speed will first be increased further.
Procedure with Stop through the control word and subsequent synchronization after
canceling the Stop:
– The Stop command is requested through the Z108.1– Control word Bit 8 = 1.
– Automatic activation of the internal ramp generator using Parameters Z145.7– to
Z145.9–. Disconnect the slave axis from the main axis set value.
– The target speed for the ramp generator is set to 0.
– The speed actual value of the slave axis, under consideration of the inverse trans-
mission factor, corresponds with the start speed for the ramp generator.
– The Stop cannot be ended until the speed set value at the output of the ramp gen-
erator has reached 0.
– The stop is canceled by deleting the control word Bit 8.
– After canceling the Stop, the target speed of the ramp generator is set to the current
speed set value of the master axis.
