Note 1: Negative voltage will cause a large surge current. Protection fuse needed if battery polarity inversion is possible

Note 2: Can be even higher because of regeneration voltage. Never inject a DC voltage from a battery or other ﬁxed source

Note 3: Minimum voltage must be present on VBat or Power Control wire

Note 4: Factory default value. Adjustable in 0.1V increments

Note 5: Current consumption is lower when higher voltage is applied to the controller’s VBat or PwrCtrl wires

Note 6: Estimate. Limited by case temperature. Current may be higher with better cooling

Note 7: Factory default value. Adjustable in 0.1A increments

Note 8: Factory default value. Time in ms that Stall current must be exceeded for detection

Note 9: Controller will stop until zero command given in case of short circuit detection

Note 10: Approximate value

Note 11: Factory default value. Time in ms for power to go from 0 to 100%
