Where working with consumers which have high interference emissions, make available a separate power supply for the cable transducer. Unused outputs must not be connected. Failure to observe these instructions can result in malfunctions, material damage or personal injury. Baumer – Sensor Systems s.r.l.

The step size for all position objects can be adapted in the object 0x6005. The basic unit is nanometer Example 1: A position step setting of 1’000’000 nm/step means that the position output unit is 1mm. Baumer – Sensor Systems s.r.l.

0x00 5.3.10 Angle Digital Filter Configuration (2603h) For GCA3/5 (C60/C80) the IIR coefficient is expressed in tenths of hertz. E.g.: Fc = 3 Hz -> 30d(0x1E). The value can be selected in a range from 0 to 300(30Hz). While for all the other type of GCA, The IIR coefficient is expressed in % (lower values->more filtering).
Considering a resolution of 0.1°: P0 = 0x84, P1 = 0x03 It means P = 0x00000384 (900 decimal) = 90° The channel ’b ’ is represented in a similar way. Baumer – Sensor Systems s.r.l. Baumer_GCA3-5-8-12-20_CANopen_MA_EN_Rev10.docx 12/23 03.12.2019 Chiari (Bs), Italy...
