Nservo complements the Automation 3200 "soft" controller's
network digital drives (Ndrive, NLdrive, NCdrive and Npaq), allowing any industry
standard analog transconductance amplifier (voltage command, current output)
to interface to Aerotech's digital drive network. It is connected via the IEEE-1394
(FireWire®) communication bus that provides deterministic behavior, auto-identification,
and easy software setup from the NMotion SMC software controller.
Nservo is a digital 2- or 4-axis (position and velocity) servo
controller with up to 20 kHz sample time. It is compatible with encoders or
resolvers and provides a ±10 VDC three-phase command to any amplifier.
With 11 digital inputs, 8 digital outputs, 4 analog inputs, 2 analog outputs
(in addition to the 8 analog outputs that drive the amplifier), and expandable
I/O, Nservo will accommodate most system I/O requirements. As with the Ndrive
series, only a single 4-wire cable is needed to communicate with the motion
generator on the PC. Other features include limits, E-Stop, brake, auxiliary
feedback input, high-speed latching inputs, and Ethernet.
Nservo offers three different options to make your retrofit
easy and economical. The standard Nservo (Nservo-DB) may be used to upgrade
an existing Aerotech system with analog servo amplifiers, such as Aerotech's
BA amplifier series, to the Automation 3200. Aerotech's DR300/DR500/DR600/DR800
drive racks may also be upgraded via the Nservo with the -OP option. The Nservo
with -TB option may be used to interface third party, non-Aerotech servo amplifiers
to the A3200 platform minimizing wiring to separate breakout blocks.
