Important Warning:
Beware that regenerative braking can create high voltage at the controller's power inputs. Use the con-
troller only with batteries. See user manual for special precautions when using a power supply.

Note 1: Negative voltage will cause a large surge current. Protection fuse needed if battery polarity inversion is possible
Note 2: Maximum regeneration voltage in normal operation. 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: When single channel jumper is installed, current is doubled. Current must be balanced between channel to obtain max
current.
Note 7: Estimate. Limited by heatsink temperature. Current may be higher with better cooling
Note 8: Factory default value. Adjustable in 0.1A increments
Note 9: Factory default value. Time in ms that Stall current must be exceeded for detection
Note 10: Factory default value. Time in ms for power to go from 0 to 100%
