Limits

Note

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.

Voltages

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.

Temperatures

The controller can cut back power to protect the hardware from damage due to over-temperature. Refer to:

Currents

Configuration of controller current limits is not yet part of this documentation

Speed

When the controller is able to measure motor RPM (eg brushless motors) it can implement an RPM limit.
