AX2500/2850 Motor Controller User’s Manual 33
Using the Controller with a Power Supply
high current surges during motor acceleration, making it possible to use a lower
current power supply. Battery mounted in this way should be connected for the first
time only while fully charged and should not be allowed to discharge. The power
supply will be required to output unsafe amounts of current if connected directly to
a discharged battery.
• Place a resistive load in parallel with the power supply, with a circuit to enable that
load during regeneration. This solution is more complex but will provide a safe path
for the braking energy into a load designed to dissipate it. To prevent current from
flowing from the power supply into the load during normal operation, an active
switch would enable the load when the voltage rises above the nominal output of
the power supply.
