145.10 Virtual master speed set value
This parameter is the set value input for the function "virtual master axis". It specifies the
set value speed on the master axis ("in front of the transmission").
The "virtual master axis" is activated through Parameter Z145.2– Mode Bit 0-3 = 0010.
145.11 Virt. master set value cycle time
This parameter is only effective in the function "virtual master axis". Changes in the pa-
rameter only become effective when the controller is blocked.
The interpolation cycle setting for the set value speed (Z145.10– Virt. master speed set
value) is entered here. Bit 12 must also be set in Parameter Z145.2– Mode.
Interpolation does not occur with a value of 1 ms and the Z145.10– is directly (not inter-
polated) transferred to the transmission input).
The parameter may also be a multiple of the fieldbus cycle, such as Fieldbus cycle = 2 ms
and set value cycle = 6
ms. In the example this means that the control must only send a
newly calculated speed set value to the controller every third fieldbus cycle.
145.12 Master speed
This parameter indicates the effective set value speed in front of the transmission.
In the case of the actual master axis, the current speed of the master axis encoder will be
shown. This also applies to a Stop or speed synchronization, although the set value of the
ramp generator affects the transmission input here.
In the case of the virtual master axis, the set value speed at the output of the ramp gen-
erator or interpolated set value speed will be displayed.
145.13 Master position revolutions
The parameter shows the number of revolutions in the position set value of the master
axis ("in front of the transmission").
In the case of the actual master axis, the actual value of the master axis encoder will be
shown. The parameter will only be updated in the "Operation enabled" status.
In the event of the virtual master axis, the value is included through integration of the set
value speed and may be set to a blocked status.
145.14 Master position angle
The parameter shows the angle of the position set value of the master axis ("in front of
the transmission") in 32 bit resolution.
