Controller grounds connection

Function

The controller contains several grounds which are connected to the connectors' pins as shown in the sheme below. Connection between controller heatsink and batt- terminal is also depicted here. Galvanic isolation between GND and GNDIO is meant only as functional isolation to prevent signal inputs and communication interfaces from noise. During normal operation voltage between GND and GNDIO should be close to zero (several volts maximum).

Scheme

Power circuit

Function

The power circuit provides power to the controller's logic. Power to the internal SMPS (Switched-Mode Power Supply) is controlled by an electronic switch. There are several options for powering on/off, which are described below.

Constant on

• The device turns on when the battery voltage is applied to the battery terminals and off when removed.

Internal HW configuration for this variant:

• Key resistor - Attached
• Flip-flop - Removed
• Internal fuse - Attached

Flip-flop

• The device turns on once the battery voltage is applied to the battery terminals and a voltage above 10V is applied to the power pin. The latching function of the flip-flop ensures that it remains turned on even when the voltage on the power pin is disengaged.
• The device turns off once a voltage below 1V is applied to the power pin (usually done by connecting the pin to the GND).
• It is also possible to turn off the device by FW.

Internal HW configuration for this variant:

• Key resistor - Removed
• Flip-flop - Attached
• Internal fuse - Attached

Activation input

• The device turns on once battery voltage is applied to the battery terminals and a voltage above 10V is permanently applied to the power pin.
• The device turns off once the voltage is removed from the power pin.

Internal HW configuration for this variant:

• Key resistor - Removed
• Flip-flop - Removed
• Internal fuse - Attached

General purpose analog/digital inputs

Function

These inputs can be used for processing analogue and digital voltage levels. These inputs are galvanically isolated from the Power GND, motor sensor GND and external UART GND. The controller offers several isolated power sources. These can be used as a power source for the external components (e.g. throttle). Pull-up and pull-down resistors on all inputs can be set individually by FW parameters.

Motor position sensor

Variant - a

Function

Motor position sensor variant "a" can process 3 hall sensors or sin/cos position sensors and 2 inputs that can be used as non-isolated digital inputs (more information about DINs here).

HALLV/SIN and HALLU/COS inputs have combined functions. These inputs can process digital as well as analogue signals, which means that can be used for sensing two state Halls and also sin and cosine signals. HALLW/COM can be used only for sensing digital signals. All these inputs work in the range from 0 to 5 V. Reference potential is shared with the main GND (internally connected to BATT-).

Scheme

variant - r

Function

Motor position sensor variant "r" can excite the motor resolver and process signals from it.

HALLV/SIN and HALLU/COS inputs can process analogue signals and are used for sensing sin and cos outputs from the resolver. HALLW/COM is used as common ground for the sin and cos outputs. Excitation for the resolver is taken from ENCA and ENCB/DATA. The reference potential is shared with the main GND (internally connected to BATT-).
