Revision as of 19:07, 14 August 2013
The Machine tab serves following purposes:
- Choose axis type (linear/rotary) and its scale
- Set motor type and properties
- Set feedback device types and properties
Parameters
Axis mechanics
| Short GUI name | GUI name | Description | How to use |
|---|---|---|---|
| AXT | Axis type & units | Select axis type and real world units used | Choose your mechanical axis type here. AXT and AXS affect only the unit conversion of Granity parameters (such as accel/velocity limit unit conversions), no effect on drive operation. |
| AXS | Axis scale | Set axis travel per motor revolution | Determine how much your axis moves per revolution and enter it here. I.e. if you have selected Linear[mm] as AXT, then calculate and enter how many millimeters axis moves per revolution. AXT and AXS affect only the unit conversion of Granity parameters (such as accel/velocity limit unit conversions), no effect on drive operation. |
Motor parameters
| Short GUI name | GUI name | Description | How to use |
|---|---|---|---|
| MT | Motor type | Motor type to be driven | Choose your motor type |
| MCC | Continuous current limit | Motor continuous current limit (peak value of sine in AC/BLDC modes, not RMS) | Use value from your motor data sheet or any lower value to reduce torque. If your AC/BLDC motor phase current is specified as RMS value, then multiply it with 1.41 to get peak value of sine. |
| MMC | Peak current limit | Motor peak current limit (peak value of sine in AC/BLDC modes, not RMS). Drive outputs this current to motor for max of 2 second duration and then falls back to the continuous limit (MCC). MCC will be also used if motor temperature modeling (see MTC) indicates maximum temperature. | |
| MR | Coil resistance | Motor phase-to-phase winding resistance | See motor data sheet and enter the value here |
| ML | Coil inductance | Motor phase-to-phase winding inductance | |
| MTC | Thermal time constant | Motor thermal time constant value in seconds, used for thermal modeling of motor to avoid motor overheating with peak current (MMC) | Refer to your motor data sheet for correct value. If not available, use formula 300*motor_weight (kg) as approximate. |
