ClearPath completes the auto-tuning process but
experiences certain warnings or shutdowns during

voltage and/or current capability.
If you suspect your power supply is underpowered, yo

•
Lower the commanded acceleration and/or velocity.
Sometimes lowering commanded acceleration and/or velo
can reduce the burden on a weaker power supply enough
eliminate shutdowns caused by "power starvation".
•
Upgrade to a more powerful supply. Look for a supply
with higher voltage, higher peak and continuous current
ratings, and a large capacitor bank.
•
Modify your existing power supply. In some cases adding
a large capacitor and a few inexpensive compone

before making any modifications to a commercial product.
