Pin A21 CAN H1
CAN High communications can line to the Calibrator, Display or other Controller(s) CAN Devices.
Pin A22 CAN L1
CAN Low communications can line to the Calibrator, Display or other Controller(s)/CAN Devices.
Pin A23 CAN 0V
This pin is the 0V reference for the CAN bus and has different specification depending on the hardware
available.
In Simga2NControllers with non-isolated CAN bus, this pin is tied to battery ground.
In Simga2NControllers with isolated CAN bus (part number ending with letter C), this pin must be connected to
the output of the 12-24V isolator.
Pin A24 CAN 120R Link
This pin is connected to a 120 Ohm resistor. If the controller is the CAN network wiring ending node, this pin
could be connected to the pin 25 or pin 21.
Pin A25 CAN H2
CAN High communications can line to the Calibrator, Display or other Controller(s) CAN Devices.
Pin A26 CAN L2
CAN Low communications can line to the Calibrator, Display or other Controller(s)/CAN Devices.
In Simga2NControllers variant with non-isolated CAN bus, the can communication lines are
referred to battery ground.
In Simga2NControllers variant with isolated CAN bus (part number ending with letter C), the
CAN lines must be supplied with an external 12 or 24 V supply.
Pin A27 Sensor supply +5V / +12V
Supply output for motor position/speed sensor (Analogue Sine/Cosine or Hall Sensor). It delivers 5V or 12V
according to the motor sensor supply selected in “Menu 3 “Autotuning”. If it is set to 0 the supply is 5V, if set
to 1 supply is 12V. The current capability is 70 mA.
Pin A28 Encoder 1 - Hall 1 i/p
This pin has to be connected to the encoder channel A (channel 1) or to the Hall sensor channel 1, depending
on the sensor technology selected in “Menu 4 “Autotuning”.
The motor encoder is normally a ‘Quadrature’ type, which has 2 outputs, ‘A’ and ‘B’. Both outputs produce a
symmetrical square wave. Between A signal and B signal a 90° phase shift has to be present.
Pin A29 Encoder 2 i/p - Hall 2 i/p
This pin has to be connected to the encoder channel B (channel 2) or to the Hall sensor channel 2, depending
on the sensor technology selected in “Menu 4 “Autotuning”.
The motor encoder is normally a ‘Quadrature’ type, which has 2 outputs, ‘A’ and ‘B’. Both outputs produce a
symmetrical square wave. Between A signal and B signal a 90° phase shift has to be present.
Pin A30 Hall 3 i/p
This pin has to be connected to the Hall sensor channel 3, if the Hall sensor technology is selected in “Menu 4
“Autotuning”. This pin is used in PMS motor application.
Pin A31 Encoder supply 0V
This pin is the ground line for motor’s speed/position sensor.
Pin A32 Motor Sensor Sine
This pin has to be connected to Sine output of analog sine cosine sensor if SineCos sensor technology is selected
in “Menu 4 “Autotuning”. This pin is used in PMS/IPM motor application.
Pin A33 Motor Sensor CoSine
This pin has to be connected to Cosine output of analog sine cosine sensor if SineCos sensor technology is
selected in “Menu 4 “Autotuning”. This pin is used in PMS/IPM motor application.
