Sigma II Servo Systems are
available in 35 sizes with peak
torques of 13.5oz.in. to
14,558in.lb. Whether you require
110VAC single-phase, 230VAC
three-phase, or 480VAC three-
phase, incremental or absolute
encoder feedback, holding brake
options or units that fit into a tight
mounting space requirement,
there is a Sigma II Servo System
to fit your needs.

A small package size, ruggedness
and reliability are achieved
through the use of surface-mount
technology and minimal internal
wiring in the amplifiers, as well as
durable TENV construction in the
servomotors. The Sigma II Servo
system far exceeds the industry
standard dollar per length and
power per size class, allowing
your factory to achieve maximum
performance from a minimum
floor space and cost.
The Sigma II power supplies for the main and control circuits are isolated from each other to provide greater
safety and easier maintenance. If an alarm occurs, only the main circuit needs to be shut down. Safety
features embedded in Sigma II firmware simplify motion programming. Sigma II safety checks also prevent
unsafe boundary conditions for system power components. Coordinated surge current protection for AC
rectifiers, power IGBTs, and braking resistors are included with all amplifiers. All Sigma II Servo products are
compliant with the following international safety requirements:
