General
Characteristics
The Lexium 17S SERCOS drives are available in five peak output current ratings
(4.2, 8.4, 16.8, 28 and 56 A) that are partitioned into two groups based on the width
of the package; the 70 mm drives are rated to handle currents up to 28 A and the
120 mm wide drive is rated to handle currents up to 56 A. All Lexium drives operate
with an input voltage which may range from 208 V -10% 60 Hz, 230 V -10%
50 Hz through 480 V +10% 50-60 Hz.
Each drive provides:
l Direct shield connection points
l Two analog setpoint inputs
l Integrated and electrically isolated RS-232 communications
Primary Power A single phase input supply may be used for commissioning and set-up and for
continuous operation with various smaller drive/motor combinations. See the
Lexium 17/ BPH motor torque speed curves for details.
Fusing (e.g. fuse cut-out) is provided by the user.
Bias Power The 17S drive requires 24 Vdc bias power from an external, electrically isolated
supply.
EMI Suppression EMI suppression for the 17S drives is integrally provided by filters on both the
primary power (EN550011, Class A, Group 1) input as well as on the 24 Vdc bias
supply (Class A) input.
