Member Data Documentation

chopperHysteresis_V

template<typename CommType >

std::optional<float> tmc9660::TMC9660< CommType >::Brake::BrakeConfig::chopperHysteresis_V

Brake chopper hysteresis in volts (optional, default: 2.0V).

Hysteresis for brake chopper threshold to prevent oscillation. Typical values: 1.0-5.0V (default: 2.0V) Brake chopper hysteresis [V] (optional, default: 2.0V)

chopperVoltageThreshold_V

template<typename CommType >

std::optional<float> tmc9660::TMC9660< CommType >::Brake::BrakeConfig::chopperVoltageThreshold_V

Brake chopper voltage threshold in volts (optional, default: 30.0V for 24V systems).

Voltage at which brake chopper activates to dump excess energy. Typical values:

• 24V systems: 28-32V (default: 30.0V)
• 48V systems: 56-60V
• 12V systems: 14-16V Brake chopper voltage threshold [V] (optional, default: 30.0V)

enableChopper

template<typename CommType >

std::optional<bool> tmc9660::TMC9660< CommType >::Brake::BrakeConfig::enableChopper

Enable brake chopper (optional, default: false).

When enabled, the brake chopper activates when bus voltage exceeds the threshold, dumping excess energy into a resistor. Enable brake chopper (optional, default: false)

holdingDutyCycle

template<typename CommType >

std::optional<uint8_t> tmc9660::TMC9660< CommType >::Brake::BrakeConfig::holdingDutyCycle

PWM duty cycle for brake holding in percent (optional, default: 30%).

Duty cycle used to hold brake in released state. Range: 0-99% (default: 30%) Brake holding duty cycle [0-99%] (optional, default: 30%)

invertOutput

template<typename CommType >

std::optional<bool> tmc9660::TMC9660< CommType >::Brake::BrakeConfig::invertOutput

Invert brake output polarity (optional, default: false).

When true, inverts the brake output signal polarity. Invert brake output (optional, default: false)

releasingDuration_ms

template<typename CommType >

std::optional<uint16_t> tmc9660::TMC9660< CommType >::Brake::BrakeConfig::releasingDuration_ms

Brake release duration in milliseconds (optional, default: 100ms).

Duration of initial high-duty-cycle phase for brake release. Range: 0-65535ms (default: 100ms) Brake release duration [ms] (optional, default: 100ms)

releasingDutyCycle

template<typename CommType >

std::optional<uint8_t> tmc9660::TMC9660< CommType >::Brake::BrakeConfig::releasingDutyCycle

PWM duty cycle for brake release in percent (optional, default: 50%).

Duty cycle used during initial brake release phase. Range: 0-99% (default: 50%) Brake release duty cycle [0-99%] (optional, default: 50%)
