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.

Command, I/O and Sensor Signals Specifications

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 VMot 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 VMot or PwrCtrl wires

Note 6: Max value is determined by current limit setting. Duration is estimated and is dependent on ambient temperature

cooling condition

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%
