2.1.2 Current
When STF dr i ves wor k wi t h di �er ent mot or s, t he r ecommended power suppl y out put cur r ent
capaci t y under di �er ent suppl y vol t age i s shown i n bel ow t abl e. The STF dr i ve power suppl y
current is lower than the the winding currents because it uses switching amplifiers to convert a
high voltage and low current into low voltage and high current. The more power supply voltage
exceeds the motor voltage, the less current will be required from the power supply.
I t i s i mpor t ant t o not e t hat t he cur r ent dr aw i s si gni ficant l y di �er ent at hi gher speeds dependi ng
on the torque load to the motor. Estimating how much current is necessary may require a good
analysis of the load to the motor.

2.2 Connecting the Power Supply
STF-4X products share a power connector. The first digit on the left side of the connector is the V+
of the power supply, and the second digit is the V- of the power supply.
(NOTE: Be careful not to reverse the wires. Reversing the connection may open the
internal fuse on the drive and void the warranty.)
