Sensors are fed via the IO-Link master, and the correct assignment is checked in the
drive controller. If no optional sensors are connected, the default value -999 is output.
The sensor at port 1 is necessary for the function while the sensors at port 2 ... 6 are
optional sensors. Retrofitting sensors is possible. After their first use, optional sensors
are monitored for availability. Thus, the sensor technology can be easily extended in
deviation from the condition as supplied.
Sensor ABZMS-41-1X/0500/LTD/DC-K24 (6.120) at port 1 of the IO link gateway is
Oil level and oil
used to measure the oil level and the oil temperature.
temperature
The measured value for the oil level is scaled linearly from % in liters. The scaling can
be adjusted via the parameters P-0-1311[160] – P-0-1311[163]. The oil temperature
is displayed in P-0-1279 and the oil level in P-0-1291.
