Function:
Enter here the acceleration for the virtual master in Hz/s.
Virtual master acceleration =
Pulsfrequenz H z
Example: The virtual master must correspond to an encoder
with 1024 inc/rotation. The maximum speed of 25 encoder ro-
tations per second must be attained in 1 second.
Virtual master acceleration =
1
25
s
Function:
Enter here the maximum speed of the virtual master in Hz.
Virtual master maximum speed =
I ncrements
Rev
Example: The maximum virtual master signal must correspond
to an incremental encoder with 1024 inc/rotation at a rotational
speed of 50 rotations/s.
Virtual master maximum speed =
1024
1
Function:
This parameter is used to select the control source in test run
mode (par. 33-80 = "1"). There can only be one control source
at a time: Digital inputs or field bus control word. Only exception
is input 27 which is always stop also with field-bus control.
When digital control is selected status signals are updated on
the digital outputs, when field bus control is selected status sig-
nals are updated on digital outputs as well as field bus.
Digital Inputs "0" means that all control commands are activated via the digital
inputs according to the description of the terminals.
Fieldbus "1" means that all control commands are activated via the field
bus control word according to the description of field bus con-
trol.
