1.3 How settings are numbered in this document
The settings (i.e. parameters) are labelled with the following format:
Mxx.yy-zz AAAAAAAAAAAA, “BBBBBBBBB”
Where:
• xx is the menu’s number;
• yy is the sub-menu’s number
• zz is the parameter’s position in the menu;
• AAAAAAAAAAA is the parameter short description;
• BBBBBBBBBBBB is the text which appears on the DMC Calibrator’s menu;
For example
M5.2-1 Motor temperature sensor type “MtempTyp”
• 5 is the calibrator menu number (in this case Menu 5 Limits Setup);
• 2 is the calibrator sub-menu number (in this case Sub-menu 2 Motor thermal limits)
• 1 is the setting number;
• “Motor temperature sensor type” is a short description of the parameter;
• “MtempTyp” is the text label appearing on the calibrator display;
1.4 How to correctly and time-efficiently setup a controller
This paragraph aims at briefly explaining the best procedure for a correct and time-efficient setup of a DMC
Simga2NController.
The Simga2Nhas 9 parameter menus which can be set up, but several settings in the Adjustment menu are displayed
on DMC Calibrator based upon the choice of settings in the other menus. For a clear Controller tuning the following
procedure should be adopted:
1) Enter the “Menu 2 “Controller Setup” for traction software” and set up the basic controller settings. (Mind that
the setting of several parameters such as “M3-16T Active low or high digital inputs ”ActvL/H”” should be
coherent with the hardware wiring performed). Pay attention on the setup of the Line Contactor, Electro-
Magnetic Brake and Power steer outputs voltages. Too high voltages can overheat of damage the component,
thus connect them only having tuned those parameters. If voltage are set to low user may experience Line
contactor not closing or Electro Magnetic Brake not releasing. Factory default values are set to 12V.It is very
important to set the proper voltage to make driver output properly working and controlling the devices
connected.
2) Enter the “Menu 5 “Limits Setup”” and set up the desired limitations.
3) Enter the “Menu 3 “Autotuning”” and set up the motor’s basic set of parameters necessary to perform
autotuning. Mind that the parameters “Maximum motor current” and “Maximum motor frequency” are very
important, as they define the maximum current that will flow into the motor (and thus the maximum
deliverable torque) and the maximum rotor speed, on which all the speed limits and ramps will be based. Those
parameters are here reported without the associated number since it varies within different motor
technologies. For more accurate information about those parameters and Autotuning procedure please refer
to the motor technology manual of interest ([4] for AC, [5] for PMS and [6] for IPM).
4) Perform the autotuning.
5) In case a Sigmagauge or a DMC Display is used, enter the “Menu 6 “B” menu and setup the parameters for BDI
calculation.
6) In case the DMC Simga2NController should operate in a CAN network, enter the “Menu 7 “CAN Bus Setup””
menu and setup all the CAN communication parameters.
7) Connect the DMC Simga2NController on the CAN bus.
8) Enter the “Menu 1 “Adjustment” for traction software” menu and setup all the necessary adjustments. It is
very important to modify the settings in this menu only when the above steps have been completed, as several
adjustments are available only when some combination of parameters in other menus are performed.
9) If necessary, modify the parameters in “Menu 4 “Motor Setup””.
