Product Description
This installation guide describes the Drum HV (High Voltage) servo drive and the steps for its
wiring, installation and power-up. Following these guidelines ensures optimal performance of
the drive and the system to which it is connected.
2.1. Drive Description
The Drum HV (High Voltage) series of digital servo drives are highly resilient and designed to
deliver the highest density of power and intelligence. The Drum HV (High Voltage) delivers up
to 65 kW of continuous power in a compact package.
The digital drives are based on Elmo’s advanced SimplIQ 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 Drum HV (High Voltage) 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 Drum HV (High Voltage), as part of the SimplIQ product line, is fully
programmable with Elmo’s Metronome motion control language.
Power to the drives is provided by a DC power source (not included with the Drum HV (High
Voltage)).
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 Drum HV (High Voltage) 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
of 18 to 30 VDC.
Whenever backup functionality is not required, Drum HV (High Voltage) models that do not
have the S suffix in the catalog number (only for the 400 V model -see page 18) can be used,
i.e., they do not have a 24 V control supply. In these models, a smart control-supply algorithm
enables the Drum HV (High Voltage) to operate with only the main power supply VP+ and VN-,
with no need for a 24 VDC auxiliary power supply for the logic.
