Based on Elmo Motion Control’s innovative ExtrIQ core technology, they support a wide range
of motor feedback options, programming capabilities and communication protocols.
2.2. Drive Description
The Eagle HV series of digital servo drives are highly resilient and designed to deliver the
highest density of power and intelligence. The Eagle HV delivers up to 65 kW of continuous
power in a compact package.
The digital drives are based on Elmo’s advanced ExtrIQ motion control technology. They
operate from a DC power source in current, velocity, position and advanced position modes, in
conjunction with a permanent-magnet synchronous brushless motor, DC brush motor, linear
motor or voice coil. They are designed for use with any type of sinusoidal and trapezoidal
commutation, with vector control. The Eagle HV can operate as a stand-alone device or as part
of a multi-axis system in a distributed configuration on a real-time network.
The drives are easily set up and tuned using Elmo’s Composer software tools. This Windows-
based application enables users to quickly and simply configure the servo drive for optimal use
with their motor. The Eagle HV, as part of the ExtrIQ product line, is fully programmable with
Elmo’s Composer motion control language.
Power to the drives is provided by a DC power source (not included with the Eagle HV).
Since the power stage is fully isolated from the control stage, the DC rectifier can be fed directly
from the mains, without the need for a bulky and expensive transformer.
If backup functionality is required to store control parameters in the event of a mains power
outage, then an S-model Eagle HV should be used, with an external 24 VDC isolated supply
connected to it.
Note:
The backup functionality can operate from an isolated voltage source within the range
from 18 to 30 VDC.
Whenever backup functionality is not required, Eagle HV models that do not have the S suffix in
the catalog number (only for the 400 V model -see page 19) can be used, i.e., they do not have
a 24 V control supply. In these models, a smart control-supply algorithm enables the Eagle HV
to operate with only the main power supply VP+ and VN-, with no need for a 24 VDC auxiliary
power supply for the logic.
