II. Driver Configuration

This section covers basic driver setup, including motor identification and parameter configuration.

Powering Up the Controller​

Proceed with Caution

Motor Identification​

Covers the minimum to make the motor work. Required scripts are located in c:\silixcon\scripts\configuration\First_run\.

tip

Alternatively, check the guided indentification

Sensor Configuration​

info

Required only for VECTOR drive (FOC) firmware. Skip for BLDC firmware (BLDC supports hall sensors only).

Drive Type

Execute 1-Motor_sensor_selection.ys and follow prompts.

Sensor Configuration

Script Functions:

  • Controller authentication
  • Sets /driver/prest to specified value
warning

Sensor support varies by application modification (mod). Details

Stator Current Configuration​

  • /driver/iref: Maximum stator current [A] (amplitude, not RMS)
  • /driver/ipeak: Must exceed iref (recommend default value)

Motor Pole Pair Setting​

Set /driver/motor/pp to motor's pole pair count. Required for accurate speed measurement and limiting.

Automatic Identification​

Execute 2-Motor_identification.ys and follow prompts.

warning
  • Battery must operate within ubmin and ubmax limits
  • Ensure unloaded motor with free rotation

Motor Thermal Protection Setup​

Optional but recommended. Prevents motor thermal damage.

  • /driver/limiter/mtemplo: Initial limitation temperature
  • /driver/limiter/mtemphi: Maximum limitation temperature

Values in [ohm] (motor temperature sensor resistance).

info

Monitor temperature via /driver/motor/Rthermistor.

Battery Limiter Configuration​

Optional settings. Zero values disable DC-side voltage/current limitation.

  • /driver/limiter/ubmax: Maximum battery voltage
  • /driver/limiter/ubmin: Minimum battery voltage
  • /driver/limiter/ibpos: Maximum discharge current
  • /driver/limiter/ibneg: Maximum regeneration current (negative value)

Battery Limits

info

Rotation Direction​

Vehicle forward direction is defined by spin-up rotation during the identrun procedure.

If you saw the opposite direction:

Change by wire swap​

  • Swap any two motor phases
  • Requires re-identification

Change by parameter​

Invert /driver/ipeak value:

  • Forward: /driver/ipeak = 200 [A]
  • Reverse: /driver/ipeak = -200 [A]
note

Physical wire swap is preferred. Changing with ipeak can lead to unexpected vehicle reversing, if you lose the configuration with this setting.
