3.5. DC Power Supply
The DC power supply can be at any voltage in the range defined in the technical specifications (see
the
Appendix of this manual). The supply source must comply with the safety aspects of the
relevant requirements, in accordance with the most recent version of the standard EN 60950 or
equivalent Low Voltage Directive Standard, all according to the applicable overvoltage category. If
the power source to the power supply is the AC line (through an isolated or a non-isolated
transformer), safety margins must be con in order to avoid activating the
undervoltage/overvoltage protection due to line variations and/or voltage drop under load.
In addition to the above, the transformer must comply with the safety aspects of the relevant
requirements in accordance with the most recent version of the standard EN 60742 (Isolating and
Safety Isolating Transformers). The nominal DC bus voltage should be in the following range:
1.2 V
dcmin
< V
dc
< 0.9 V
dcmax
Where:
V
dcmin
is the minimum DC bus
V
dcmax
is the maximum DC bus
The transformer power should be calculated such that it will be able to deliver power to the
amplifier (including peak power) without significant voltage drops.
The power supply should be located as close as possible to the amplifier. While driving high-inertia
loads, the power supply must be equipped with a shunt regulator; otherwise, the amplifier will be
disabled whenever the capacitors are charged above the maximum voltage, during motor break
down.
3.5.1. Powering Up
After the Eagle has been mounted, check that the cables are intact. The Eagle servo drive is then
ready to be powered up.
Caution: Before applying power, ensure that the DC supply is within the range
specified for your specific type of Eagle and that the proper plus-minus
connections are in order.
3.5.2. Initializing the System
After the Eagle has been connected and mounted, the system must be set up and initialized. This is
accomplished using the Composer, Elmo’s Windows-based software application. Install the
application and then perform setup and initialization according to the directions in the Composer
Software Manual.
