This section applies for: robolink DCI, robolink, drylin gantry or drytech delta with modular control, both via USB and embedded. It does not apply for the Mover robots.
CPRog allows to set all firmware parameter of the motor controller. This is done either directly using the USB-CAN-Adapter, or via Ethernet and the TinyCtrl software on the embedded Linux board.
General Procedure
- Make a backup of the current firmware parameter
- Adapt the values in the backup file
- Upload the file again
Parameter File
The parameter files contain a set of parameter for each joint of the robot:
<Joint0 ID="16" ComTimeOut="2000" MaxCurrent="200" MaxLag="5000" PosP="1.000" PosI="0.000" PosD="0.000" PosAWU="30.000"
Encoder="True" SwapEncoderDirection="False" EndSwitchRising="True" StopOnEndSwitch="False"
RefStraight="False" RefSinus="False" RefHalf="True" SinusRefTics="2000" SinusRefMaxCycles="6"
Offset="0" RefSpeed="50" RefSpeedSlow="10" RefFromBothSides="True"
SGThreshold="2" CSLoad="20" CSStart="20" CSIdle="6" CSRef="18" StartArea="200"
MinSupplyVoltage="500" MaxTemperature="500" Microstepping="128"/>
Floating point values have to be separated by '.', not by ','!
The most important parameter are:
- Offset: This value defines the offset between reference position and zero position. The unit is encoder tics. In the c:/CPRog/Data/Robots/ folder you can find a .xlsx sheet for translation degree <-> encoder tics.
- CSLoad: Defines the motor current while running. Values from 1 (minimum) and 31 (maximum) are allowed.
- CSStart: Defines the motor current while starting (low rpm). Values from 1 (minimum) and 31 (maximum) are allowed.
- CSIdle: Defines the motor current while not running. Values from 1 (minimum) and 31 (maximum) are allowed.
- CSRef: Defines the motor current while referencing. Values from 1 (minimum) and 31 (maximum) are allowed.
The following parameter should only be changed when you are aware of the usage:
- PosP: Proportional parameter of the position PID control. Around 1.0 for robots with motor encoder
The files are stored in two locations:
c:/CPRog/Data/Backup/filewithdateandtime.datfor the backup files from your robot- e.g.
c:/CPRog/Data/Robots/igus_5DOF_BV/igus_5DOF_BV_DiscHalfRef_AmpParameter.datfor general presets based on the robot type
Detailed Procedure
- Open CPRog
- Connect to the robot via USB-CAN-Adapter or Ethernet
- Open the backstage menu by clicking "File" at the top left
- Click "Get Amp configuration" (see the image below)
- Now a backup file is written in c:/CPRog/Data/Backup
- Change the file according to your requirements, e.g. adapting the offsets
- Click "Set Amp configuration"
- Choose the updated .dat file
- Wait until all parameters are written, approx 20s
- For some parameter, e.g. the encoder direction, the control needs a cold restart
- Test if the changes result in a better performance.
