Member Function Documentation

int CanCtrlPltfCOb3::ElmoRecordings	(	int	iFlag,
		int	iParam,
		std::string	sString
	)

Provides several functions for drive information recording purposes using the built in ElmoRecorder, which allows to record drive information at a high frequency.

Parameters:

iFlag

To keep the interface slight, use iParam to command the recorder: 0: Configure the Recorder to record the sources Main Speed(1), Main position(2), Active current(10), Speed command(16). With iParam = iRecordingGap you specify every which time quantum (4*90usec) a new data point (of 1024 points in total) is recorded; 1: Query Upload of recorded source (1=Main Speed, 2=Main position, 10=Active Current, 16=Speed command) with iParam and log data to file sParam = file prefix. Filename is extended with _MotorNumber_RecordedSource.log 99: Abort and clear current SDO readout process 100: Request status of readout. Gives back 0 if all transmissions have finished and no CAN polling is needed anymore.

Returns:: -1: Unknown flag set; 0: Success; 1: Recorder hasn't been configured yet; 2: data collection still in progress

Definition at line 1492 of file CanCtrlPltfCOb3.cpp.

int CanCtrlPltfCOb3::evalCanBuffer ( )

Triggers evaluation of the can-buffer.

Definition at line 897 of file CanCtrlPltfCOb3.cpp.

int CanCtrlPltfCOb3::getGearDeltaPosVelRadS	(	int	iCanIdent,
		double *	pdDeltaAngleGearRad,
		double *	pdVelGearRadS
	)

Gets the delta joint-angle since the last call and the velocity.

Parameters:

	iCanIdent	choose a can node
	pdDeltaAngleGearRad	delta joint-position since the last call in radian
	pdVelGearRadS	joint-velocity in radian per second

Definition at line 1404 of file CanCtrlPltfCOb3.cpp.

int CanCtrlPltfCOb3::getGearPosVelRadS	(	int	iCanIdent,
		double *	pdAngleGearRad,
		double *	pdVelGearRadS
	)

Gets the position and velocity.

Parameters:

	iCanIdent	choose a can node
	pdAngleGearRad	joint-position in radian
	pdVelGearRadS	joint-velocity in radian per second

Definition at line 1384 of file CanCtrlPltfCOb3.cpp.

void CanCtrlPltfCOb3::getMotorTorque	(	int	iCanIdent,
		double *	pdTorqueNm
	)

Gets the motor torque (calculated from motor active current).

Parameters:

	iCanIdent	choose a can node
	pdTorqueNm	motor-torque in Newtonmeter

Definition at line 1455 of file CanCtrlPltfCOb3.cpp.

void CanCtrlPltfCOb3::getStatus	(	int	iCanIdent,
		int *	piStatus,
		int *	piTempCel
	)

Gets the status and temperature in degree celcius. (Not implemented for CanDriveHarmonica)

Parameters:

iCanIdent

choose a CANNode enumatraion

Definition at line 1425 of file CanCtrlPltfCOb3.cpp.

bool CanCtrlPltfCOb3::initPltf ( )

Initializes all CAN nodes of the platfrom and performs homing procedure. !! The homing routine is hardware-dependent (steering and driving is coupled) !! !! If you use this code on other hardware -> make sure te remove or adapt homing sequence !!

Definition at line 928 of file CanCtrlPltfCOb3.cpp.

bool CanCtrlPltfCOb3::isPltfError ( )

Signs an error of the platform.

Returns:: true if there is an error.

Definition at line 1240 of file CanCtrlPltfCOb3.cpp.

void CanCtrlPltfCOb3::readConfiguration ( ) [protected]

Definition at line 244 of file CanCtrlPltfCOb3.cpp.

void CanCtrlPltfCOb3::requestDriveStatus ( )

Requests the status of the drive. Status-Msg includes whether motor is in error-state (with source, e.g. undercurrent, overheated) or operational (enabled/disabled, at its limits, ...)

Definition at line 1371 of file CanCtrlPltfCOb3.cpp.

void CanCtrlPltfCOb3::requestMotorTorque ( )

Requests motor-torque (in fact active current) of the drive.

Parameters:

iCanIdent

choose a can node

Definition at line 1442 of file CanCtrlPltfCOb3.cpp.

int CanCtrlPltfCOb3::requestMotPosVel ( int iCanIdent )

Requests position and velocity of the drive. (This is not implemented for CanDriveHarmonica. sending an Velocity command to an ELMO Harmonica-Ctrl triggers a aswer transmitting the current velocity)

Parameters:

iCanIdent

choose a can node

Definition at line 1352 of file CanCtrlPltfCOb3.cpp.

bool CanCtrlPltfCOb3::resetPltf ( )

Reinitializes the nodes on the bus. The function might be neccessary after an emergency stop or an hardware failure to reinit drives.

Definition at line 1205 of file CanCtrlPltfCOb3.cpp.

void CanCtrlPltfCOb3::sendNetStartCanOpen ( ) [protected]

Starts up can node
