Detailed Description

Movement limitations and settings, related to the motor.

This structure contains useful motor settings. These settings specify motor shaft movement algorithm, list of limitations and rated characteristics. All boards are supplied with standard set of engine setting on controller's flash memory. Please load new engine settings when you change motor, encoder, positioner etc. Please note that wrong engine settings lead to device malfunction, can lead to irreversible damage of board.

Field Documentation

int Antiplay

Number of pulses or steps for backlash (play) compensation procedure.

Used if ENGINE_ANTIPLAY flag is set.

unsigned int EngineFlags
unsigned int MicrostepMode
unsigned int NomCurrent

Rated current (in mA).

Controller will keep current consumed by motor below this value if ENGINE_LIMIT_CURR flag is set. Range: 15..8000

unsigned int NomSpeed

Nominal (maximum) speed (in whole steps/s or rpm for DC and stepper motor as a master encoder).

Controller will keep motor shaft RPM below this value if ENGINE_LIMIT_RPM flag is set. Range: 1..100000.

unsigned int NomVoltage

Rated voltage in tens of mV.

Controller will keep the voltage drop on motor below this value if ENGINE_LIMIT_VOLT flag is set (used with DC only).

unsigned int StepsPerRev

Number of full steps per revolution(Used with stepper motor only).

Range: 1..65535.

unsigned int uNomSpeed

The fractional part of a nominal speed in microsteps (is only used with stepper motor).

Microstep size and the range of valid values for this field depend on selected step division mode (see MicrostepMode field in engine_settings).
