Omega Series Digital PWM Amplifier Manual
Product Description
Glentek’s Omega-SynqNet® Digital PWM Servo Amplifiers offer the latest in DSP control of rotary and
linear, brush and brushless, servo motors combined with the power and flexibility of the SynqNet® Net-
work. The Omega-SynqNet® amplifiers feature one of the industry’s highest PWM update rates (up to
24kHz) for superior bandwidth and are designed for high performance OEM applications. These ampli-
fiers are available in a variety of power ranges and can be configured to operate directly from 110-130
VAC or 208-240 VAC main lines. They accept a wide range of incremental encoder inputs including in-
expensive, low-resolution encoders, reduced wire encoders, and fine-pitch linear scales and all models
include dedicated optically isolated I/O (limits, enable, home and fault), general purpose controller con-
figured optically isolated I/O, and high speed, general purpose, differential receivers and transmitters
for use as input captures and output compares. Initial configuration and tuning can be performed
through an RS232 port using Glentek’s Windows™ based MotionMaestro™ software or directly by the
SynqNet® controller. These amplifiers include extensive fault detection with associated 7-segment dis-
play diagnostics.
SynqNet® is an all-digital motion control interface for connections between controllers and drives de-
veloped by Motion Engineering specifically for the motion control industry. The physical layer of Syn-
qNet® is based on IEEE 802.3 standards for 100Base-TX, the physical layer of Ethernet. It supports up
to 32 coordinated axes with update rates up to 48KHz (4 axes) and cable lengths up to 100 meters be-
tween nodes. Full SynqNet® compliant drives, such as Glentek’s Omega-SynqNet® drive, synchronize
their control loop updates to the master SynqNet® drive strobe to minimizes control loop jitter and
skew resulting in improved motion control. SynqNet® facilitates remote configuration, control and moni-
toring of drives and remote drive firmware updates. The network is electrically isolated for noise immu-
nity and includes data path redundancy for fault tolerant operation. SynqNet® eliminates the traditional
noise-prone ±10V analog signal, and relocates the encoder and I/O connections, which traditionally re-
quired routing through long cumbersome cables, to the drives. The only remaining connection required
at the controller is an industry standard 100Base-Tx network cable. By locating the drives near the mo-
tors, the cabling can be kept short which aids in noise immunity, reduces EMI, and reduces cabling
complexity and cost. To learn more about SynqNet®, visit www.synqnet.org.
Features

RS-232
High speed (115.2K baud) serial communication inter
face for set-up and tuning.
•
Software Configurable
Glentek’s Windows™ based MotionMaestro™ software
provides ease of set-up and tuning with no previous
programming experience required. This software is Win
dows™ 95/98/2000 and NT compatible. Configuration
can also be performed over SynqNet®.
