4.4.1 General information
The unit has an IO-Link communication interface which requires an IO-Link capable module (IO-Link
master).
The IO-Link interface allows direct access to the process and diagnostic data and enables setting of
the parameters of the unit during operation.
You will find further information about IO-Link and all the necessary information about the required IO-
Link hardware and software at:
4.4.2 IO Device Description (IODD)
You will find the IODDs required for configuration of the IO-Link device as well as detailed information
about the process data structure, diagnostic information and parameter addresses at
4.5 SIO mode
The yellow LED indicates the switching status of the sensor.
4.5.1 Switching function normally open (low active)
Transistor output
LED yellow
State
Conducting (ON)
On
Rotational speed > SP + H and during
start-up delay
Non-conducting (OFF)
Off
Rotational speed < SP
SP = switch point
H = hysteresis
4.5.2 Switching function normally closed (high active)
Transistor output
LED yellow
State
Non-conducting (OFF)
Off
Rotational speed > SP + H and during
start-up delay
Conducting (ON)
On
Rotational speed < SP
SP = switch point
H = hysteresis
4.6 Start-up delay
The start-up delay ignores the underspeed signal in the start-up phase. After application of the
operating voltage the start-up delay is effective only once.
Linking the drive and speed monitor power supplies ensures that the start-up delay is effective each
time the machine is switched on.
4.7 Teach offset
This parameter allows setting of an offset between the taught process value and the resulting
switching value.
