Granity user guide/Goals
Granity Goals tab
The Goals tab in the GDtool 3 serves following purpses:
- Choose drive control mode
- Choose setpoint signal and its scale
- Set motion acceleration & velocity limits
- Setup |axis homing
Parameters
Selecting drive function
| Short GUI name | GUI name | Description | How to use |
|---|---|---|---|
| CM | Control mode | Select drive operating control mode | Select Torque, Velocity or Position mode. |
Setpoing input signal
| Short GUI name | GUI name | Description | How to use |
|---|---|---|---|
| CRI | Setpoint input | Source the of setpoint signal | Choose one from Serial only SMV2, Pulse and direction, Quadrature, PWM or Analog setpoint |
| CIS | Setpoint smoothing | Low pass filtering of setpoint signal | Tick the checkbox to smoothen the setpoint signal. This is useful if setpoint is noisy or jittering. However, if fastest response to the input is desired, leave this unticked. Also if using CAS>100%, this may help to smoothen the motion. |
| CAS | Setpoint scaling factor | Variable to adjust the scale of setpoint signal | Value of 100% will pass the setpoint unchanged through the setpoint scaler. For example setting 200% here will equal doubling the amplitude of setpoint signal (i.e. in pulse train mode, one pulse equals two pulses, or in analog mode 5V equals 10V). |
