Page 22: Wiring Of Digital Inputs
3.1.2 Wiring of digital inputs The DMC Sigma2 controllers have the ability to set all digital inputs at runtime as active low or as active high. This setting is made in the controller setup menu. NOTICE! It is not possible to mix active low and active high inputs.
Page 23 With some controllers it is possible to activate the common input (Din 0) using a diode from the other inputs. With the DMC Sigma2 controller this is not possible. Use a double double-throw switch instead, as displayed in the schematic below. Both inputs are activated correctly.
Page 24 Active High digital inputs For using Active High digital input The DMC Sigma2 controller must be setup for active high digital inputs by setting the parameter “M2-8Digital inputs active low/high ”ActvL/H”” to 1. Using a mechanical switch An active high digital input can be activated using a simple mechanical switch. The switch is wired between the B+ or Vbatt terminal and one of the digital inputs.
Page 25: Wiring Of Analog Inputs
The “Pin A8 Analogue supply 5V” has maximum current capability of 10mA. The “Pin A19 Supply 12V -- 70mA max.” has a maximum current capability of 70mA. Simga2N Traction Advanced Manual– V1.3 Page 25 (166) ©2021 DMC GmbH Herten Germany...
Page 26 In this case the analog/digital potentiometer has wire-off detection capability at “Pin A8 Analogue supply 5V”. The wire- off detection can be enabled by setting parameter “M2-6 Accelerator supply wire off detection ”SplyWrOf”” to 2.

Page 35 Please notice that the DC/DC converter supplying the Sigma2N key line must be at least capable of outputting 5W for supplying the control logic. In case the application needs the DMC Sifgma2N Controller to drive one or more Digital Outputs, the user should consider upsizing the overmentioned DC/DC converter taking into account 2A for each driven output.
Page 36: Mechanical Installation
3.3 Mechanical installation The DMC Simga2NController family’s mechanical dimensions are reported in the figure above. Ever through all the controllers meet the IP65 protection against dust and water, it is suggested to choose carefully the installation location to protect them from damage.
Page 37: Use Of Can Open Calibrator And Dmc Configurator
When connecting the DMC CAN Open Calibrator into a CAN network, it will communicate at a selectable baud rate. By default the DMC Calibrator is set to use 250 kbit/s baud rate. In case the baud rate of DMC CAN Open Calibrator and DMC Simga2N Controllers are not consistent, they will not communicate.
Page 38: Dmc Configurator
Adjustments and DMC Calibrator’s map The DMC Calibrator is easy to use. The “up” and “down” buttons are used for scrolling lists up and down. Selections can be made with the “SEL” button. The “plus” and “minus” buttons are used to increase or decrease the parameter’s values.

This could lead to serious safety problems and cause operator’s injuries. DMC declines any responsibility for incorrect setup of this parameters.

This could lead to serious safety problems and cause operator’s injuries. DMC declines any responsibility for incorrect setup of this parameters. These settings are part of I t function (pronounce as “I-squared-t”), that is a current limiting feature: the maximum current is limited with time.
Page 111 When the motor is running continuously for an infinite time, the motor temperature will rise to a temperature of 155 °C and will stabilize there. See also the graph below. Simga2N Traction Advanced Manual– V1.3 Page 111 (166) ©2021 DMC GmbH Herten Germany...
Page 112 The reason that percentages are used instead of real currents, is that all other limit features such as low voltage limit and controller temperature limit are also in percentages. Note that the maximum current is specified by “Maximum motor current” (adjustable in “Menu 3 “Autotuning””). Simga2N Traction Advanced Manual– V1.3 Page 112 (166) ©2021 DMC GmbH Herten Germany...

Page 115: Menu 5.9 "Speed Guard Function
Therefore if, for example, the vehicle is trying to climb a slope but is has not enough torque to succeed, the speed error will be very large and the function will recognise the “stall” condition, closing the EMbrake and avoiding the vehicle to roll back.
