3.1 Cycle by cycle current limit

Cycle by cycle current limit provides a means of controlling the amount of current delivered to the motor. This is useful when the system must limit the amount of current pulled from the power supply during motor start-up. The cycle by cycle current-limit limits the current applied to the motor from exceeding the configured threshold. Configure Cycle by cycle current limit to the rated peak phase current of the motor. Check the motor datasheet for the rated peak phase current in Amps.
