[!] This setting will indirectly adjust how much peak current is pulled from your power source. It is possible for current draw to exceed the current capacity of your power source and cause it to trip. Always test before use on set.
[i] This setting is only available on high current PCBs: MAX and SN >11000.
[!] Do not adjust this setting without understanding it. On Brushless motors, adjusting this setting too high can lead to erratic and dangerous wheel movement.
Adjusting this setting higher will mean the motors will slip at a higher threshold. Adjusting this setting lower will mean the motors will slip at a lower threshold.
The settings are measured in 0.1% deviation. For example a setting of 15 is equal to 1.5% deviation.
Deviation is the percentage difference between the motor's target position and where the motor is. The motor driver interprets this deviation as user input. The father the deviation, the stronger the user input, which then dictates how much torque the motors must apply to keep up the physics simulation based on the selected mass setting.
If the user inputs a force that is very forceful and very quick, this will demand torque and thus current from the power supply.
Too much torque means too much current and the motors must slip. The threshold for this varies and depends on the motor type and the power supply's maximum available current.
Default setting on MAX is 7 (or 0.7%).
Default on Brushless is 50 (or 5%).
The MAX and Brushless motors are entirely different, and thus have vastly different tuning. The intent of how this setting is used is also different.
MAX uses this setting mostly to limit how much current is pulled from your power supply.
Brushless wheels use this setting to avoid the motor driver from losing control over the motors after reaching Maximum Current Saturation, which is detailed below.
For MAX motors, the motors are capable of using up to 15 amps of current. This is not available from many power supplies/batteries, thus the setting must be tuned down as to prevent pulling too much current from the power supply.
Because the motors have no cogging, various other tuning parameters means the MAX wheels in general are more tightly tuned. And will pull much more current with must smaller deviations. Thus it's factory threshold is 7.
[$] It is suggested to not adjust this setting on set. With power supplies that have higher peak current, such as TB50's it is possible to the turn this setting higher. Only test/adjust with power supplies that have digital or resettable fuses.
[i] This setting adjusts the threshold for each wheel. So remember while moving one wheel may not trip your power supply at a given threshold, moving both wheels simultaneously may. You should consider the operating style and your own margin carefully.
For Brushless motors, the motors are only capable of using 2.5A of current. Above this, the motor driver will continue to make current available, but none will be used. Beyond this point, if the motor does not slip, the user will have more control over the wheel position than the motor driver, which will feel like the wheel is on a spring and as the motor driver attempts to regain control, the wheel can move unpredictably. Thus it is very important that the motor slips before this point is reached. This point is called "Maximum Current Saturation". The motors should never be allowed to pass Maximum Current Saturation.
[!] If adjusting this settings on brushless wheels, keep the mass settings low, grip the wheel firmly, make small movements. If the physics of the wheel feels disengaged, but the motor is still applying torque, the motor has passed maximum current saturation, carefully remove your hands from he wheels. If the wheel starts spinning rapidly, do not attempt to stop the wheel with your hands. Remove power and allow the wheel to come to a rest on its own. Return power, lower threshold to the default setting.
