06. Control Access
Control authority
M10x control authority is the term describing the
privileges allowing motor control operation
through M10x. It is also a setting parameter in
M10x to define which control access group has
privileges to operate the motor via M10x.
Control groups
There are three control access groups defined in
M10x:
• Local hardwiring: M10x accepts its start1/
start2/stop commands from the hardwired
inputs
• Remote fieldbus: M10x accepts its start1/
start2/stop commands from a PLC or higher
control system via fieldbus, ie, MODBUS or
PROFIBUS.
• MDx control: M10x accepts its start1/start2/
stop commands from operator panel MDx
located on the front panel of each starter unit
on switchgear.
Assign control access
To decide which of above 3 control groups may
have the control access , the selector switch func-
tion will have to be used. There are two type of se-
lector switch functions in M10x, the local selector
switch and the soft selector switch function.
When soft selector switch is used, the control ac-
cess is assigned to the control groups through
configuration. Which means the control access
have to be pre-configured and can only be
changed via parameters.. (Fig 49).
In Profibus version, i.e. M10x-P, M10x also supports
the soft selector switch from Profibus. (Fig 50).
In most applications, a physical local selector
switch is installed beside motor or on the starter
to select the control access. In M10x, the local se-
lector switch is supported via hardwiring into DIs.
(Fig 51). Local selector switch always has the high-
est control privilege out of all.

When using soft selector switch, users define the
