- What does “choke” mean?
- What does LOW mean? This came on regularly when the remote was “confused”. Now it just flashes LOW sometimes, then immediately switches to regular running.
- I don’t know what the Kint speeds are or what the settings should be for optimal running.
- Do you have supplemental instructions that explain all of the panel messages and settings?
At present mine reads (I have no idea what they mean, or if they are good or bad, or are the default settings and should never be changed):
- Kprop 125%*; Kint= 2562%/s;
- V Kprop= 2000*; V kint=9000;
- VdRon= 380V*; VdRoff= 360V;
- Thtsnk=14C; Treduc= 60C*
- DVR Upgrade kit ver: 8.18C R2VO2b
2. LOW is shown when the position sensor reads a speed reading that is below 25rpm (usually 0rpm), this can happen if there is some interference in the 10 pin ribbon cable between the motor power control board and the user interface board, this can corrupt the speed readout message even if it has no implication on the actual motor speed. It sounds like this was the case in the customer's instance.
Alternatively, it can read LOW when the motor is not running (lock pin is in place and the motor is not running) OR if there is a error on the position sensor, but if the motor is running fine, then it should not be this problem.
3. The Kint and Kprop are the control gains for motor speed control. Usually these parameters are self adjusting in the software and the user does not need to worry about these numbers. The intelligent motor control software adjust these parameters automatically based on your workpiece and the speed you're running at to optimize the performance. These internal parameters can be overwritten by the user if they wish to achieve a certain performance characteristic but those are only in the very rare cases where users want to do this.
There is a parameter called the "Speed Control" and can be selected from 3 predefined profiles, call "Soft", "Normal" and "Hard"
-Normal: The default profile for Kprop and Kint for general work
-Soft: Profile for large workpieces and large out of balance work
-Hard: For small diameter workpieces (e.g. table leg)
This parameter adjusts the Kprop and Kint automatically and so the user does not need to worry about it.
4. Usually the user does not have to worry about parameters, they are helpful for when the service center needs to resolve problems with the machine and the user can sometimes write down these parameters for the service center to resolve problems over the phone, the machine comes pre-configured and there is no need to change these parameters.
5. Kprop / Kint - speed control parameters, these are self adjusting
6. Vkprop/Vkint - voltage control parameters, does not need to be changed
7. VdRon / VdRoff - voltage reference for machine on and off, does not need to be changed
8. Thtsnk - is the temperature reading on the heatsink on the main board, the controller monitors this and reduces power output to prevent your power circuit from overheating, this is read-out only and can not be changed.
Treduc - This is the temperature threshold, if the temperature goes beyond this value, it will limit the power output to reduce the heat and protect the circuitry, does not need to be changed unless the motor is constantly overheating
9. This is the firmware number.
8.18c is the power control board firmware version, this is the latest version for the 2024 series
R2U02b is the firmware for the user interface, this is the latest version for all 2024/XP series with the latest feature developed to date (speed chart/braking/etc)
8.22c is the latest Galaxi + Galaxi HMI software.
