With the mar­ket launch of the GEMAC MOTUS in 2020, a sen­sor mea­sur­ing unit con­fig­urable for a wide range of appli­ca­tions was intro­duced, which enables 6‑axis motion detec­tion on mobile machines, such as con­struc­tion machin­ery, agri­cul­tur­al machin­ery, forestry machin­ery, crane and lift­ing tech­nol­o­gy, as well as on ships.
The mar­ket has very well received our FIRST POW­ER-IMU for high-pre­ci­sion mea­sure­ment on mobile POW­ER machines. Var­i­ous sug­ges­tions from our cus­tomers for fur­ther com­ple­tion of the scope of per­for­mance have been imple­ment­ed in new func­tion­al exten­sions. These focus in par­tic­u­lar on the pos­si­bil­i­ties for indi­vid­u­al­iza­tion in spe­cif­ic cus­tomer applications:

1. Auto­mat­ic con­fig­u­ra­tion of the mount­ing position

For the first time, GEMAC offers the option of indi­vid­u­al­ly con­fig­ur­ing the mount­ing posi­tion and axes for the tilt out­put for the entire GEMAC Motus fam­i­ly, adjustable by man­u­al para­me­ters or direct auto­mat­ic posi­tion adjust­ment. This makes it even eas­i­er and more flex­i­ble to adapt the sen­sor to the application.

2. Flex­i­ble zero adjustment

The pre­vi­ous off­set only affect­ed the plumb angle out­put. The off­set val­ues were pre­vi­ous­ly added up at the end of the incli­na­tion cal­cu­la­tion. The improved off­set set­ting now makes it pos­si­ble to rotate the sensor’s coör­di­nate sys­tem. More flex­i­ble mea­sur­ing ranges can be real­ized, and every angle for­mat can be cal­cu­lat­ed even more precisely.

3. Con­fig­u­ra­tion of sen­sor fusion

Fur­ther­more, the soft­ware imple­ment­ed an expert mode with extend­ed set­ting options, which allows a con­fig­u­ra­tion of the sen­sor fusion. Here, the new option of deac­ti­vat­ing the fil­ter dynam­ics (adap­tive damp­ing) and the man­u­al set­ting of the damp­ing fac­tor enables even more sta­ble out­put val­ues for very dynam­ic appli­ca­tions or per­ma­nent move­ment of a mobile machine.

4. Con­fig­u­ra­tion of the out­put data at SAE J1939

Until now, SAE J1939 offered only four stan­dard­ized out­put telegrams and sev­er­al pro­pri­etary telegrams with oth­er out­put data. Like CANopen, each sig­nal is assigned its ID, which can be mapped into an out­put telegram. Up to 4 sig­nals per telegram are pos­si­ble. The out­put data can thus not only be con­fig­ured and eval­u­at­ed man­u­al­ly but also individually.

5. CANopen Autostart

With this new option, it is pos­si­ble that the sen­sor goes direct­ly into the CANopen mode “Oper­a­tional” after the “Pow­er-On” or “Reset” with­out hav­ing to receive a start telegram from the CANopen mas­ter. This makes it pos­si­ble to con­fig­ure the sen­sor so that direct­ly mea­sured val­ues can be out­put with the “Pow­er-On” with­out addi­tion­al communication.
