Enhancements
The following features are incorporated into the 17S drive to facilitate the set-up 
and operation of the servo system:
l
Two analog +/-10 V inputs can be programmed for a multitude of functions 
depending upon the application. Both inputs incorporate automatic offset 
compensation, dead-band limitation and slew-rate limitation.
l
Four fully programmable 24 V discrete inputs; two of which are typically defined 
as hardware limit switches.
l
Two fully programmable 24 V outputs and a separate 24 V brake output 
capable of driving a maximum of 2 Amps.
l
An integrated and fully isolated RS-232 connection for communication with a 
PC; used to set configuration parameters and tune the system with the Unilink 
configuration software.
l
A separate 24V bias supply input which may be connected through a UPS to 
preserve system data in the event of an interruption in the AC mains supply.
