2.3.3 Current
The maximum supply currents required by the RS series step servo drive and motor are shown
below in chats at different power supply voltage input. The RS drive power supply current is lower
than the winding currents because it uses switching ampli
fi
ers 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.
It is important to note that the current draw is signi
fi
cantly different at higher speeds depending
on the torque load to the motor. Estimating how much current is necessary may require a good
analysis of the load to the motor.
