Limits are typically set to protect the controller hardware, the motor, or other system elements from damage. They should only be changed by a knowledgeable system engineer. It is usually best to change them incrementally and observe the result before continuing.
The following should be considered when setting up a new system:
- Nominal battery voltage
- Undervoltage warning limit
- Severe undervoltage (shutdown) limit. Note that the controller will not power on unless input voltage is at least as high as the shutdown limit.
- High Voltage Limit determines when the controller protects itself against unsually high input voltage.
The controller can cut back power to protect the hardware from damage due to over-temperature. Refer to:
- Controller Temperature Limit for the on-board sensor
- Motor Temperature Limit for the optional motor temperature sensor input
Configuration of controller current limits is not yet part of this documentation
When the controller is able to measure motor RPM (eg brushless motors) it can implement an RPM limit.
