    +B AT Emergency stop. Since the IQAN-MC3 is capable of implementing safety functions, it may in some applications be tempting for the designer to implement the emergency stop as a function in the IQAN-MC3. The IQAN-MC3 does not have any built in emergency stop function, but if it is implemented anyway, it must be done with extreme caution.

  • Page 29: Connecting Of Supply Voltage

    If any of the outputs are shorted to battery voltage, the module will be powered by reverse feed of voltage, even when the connection to module power is off. The IQAN-MC3 is capable of detecting if outputs are shorted to battery voltage at start- up, and will prevent the application from starting.

  • Page 30: Terminating

    When an IQANdesign application is loaded, it can set individual buses to be non-terminated. To give an IQAN-MC3 a unique address, you may use an addressing ID-tag, or an ID- tag having a combined address and terminating function. The ’T’ values of ID-tags are ignored, i.e.

    ’under/over current threshold’, see Appendix A, on page 46. An undetected error that falls within these limits can lead to an unintentional change of speed of the output, and must be safe in the application for which the IQAN-MC3 is used.
  • Page 42 The COUT current range and slopes must be limited in the application file. Due to the risks involved with modifying these adjustable values, it is recommended that these limits are kept narrow. Alternatively, the access to modification of current range and slopes can be limited. See IQANdesign user manual. Instruction book, IQAN-MC3...
