11.4 Motion control configurations
Dangerous state due to new mode!
If the mode of operation
‘modes of operation’ is changed during operation (control
word = 0xnnnF), a dangerous state may occur in the new mode.
•
BONFIGLIOLI VECTRON recommends checking the status word before changing
the mode of operation (e.g. for status 0xnn33).
Motion Control Definition
For the full function of the Motion Control Interface, you will have to set L
cal/Remote 412 = “1-Control via state machine”. In all other operation modes of p
rameter Local/Remote 412, there are major restrictions. The descriptions in t
chapter and of all objects used are based on the setting Local/Remote 412 = “1
-
Control via state machine”.
The usage of Positioning for setting Local/Remote 412 ≠ 1 is described in the “Posi-
tioning” application manual.
The function of the state machine describes the basic operating behavior of the fre-
quency inverter in configurations with position control (Configuration 30

described above support the bits marked as
operation mode specific.
These bits and bit “Target reached” have
different meanings in the different position
control operation modes – defined by m
odes of operation. The following chapters
describe the application of the operation mode specific bits in the

, depending on the different position control operation modes. The preset
mode is

= 2 – velocity mode.
The state machine must be set to “operation enabled”, before the position command
can be issued via the operation mode specific bits of the
control word
.
Once a
mode of operation
has been set by the PLC, no commands will be accepted for
this operation mode until this operation mode is displayed in the

The bits in the

marked as operation mode specific are
only supported in configurations with position control (
