Features
GFK-0356Q Chapter 8 Option Modules
Digital Signal Processor (DSP) control of GE Servos
Block Processing time under 5 milliseconds
Velocity Feed Forward and Position Error Integrator to enhance tracking accuracy
High resolution of programming units
- Position: -536,870,912...+536,870,911 User Units
- Velocity: 1 ... 8,388,607 User Units/sec
- Acceleration: 1 ... 1,073,741,823 User Units/sec/sec
Simple and powerful motion program instruction set
Simple 1- to 4-axis motion programs. Multi-axis programs using Axes 1 and 2 may utilize a
synchronized block start.
Non-volatile storage for 10 programs and 40 subroutines created with VersaPro software
(Version 1.1 or later).
Compatible with Series 90-30 CPUs equipped with firmware release 10.0 or later (will not
work with CPUs 311 – 341 and 351).
Single point of connection for all programming and configuration tasks, including motion
program creation (Motion Programs 1 – 10) and Local Logic programming. All programming
and configuration is loaded through the PLC's programming communications port. In turn, the
CPU loads all configuration, motion programs, and Local Logic programs to the DSM314
across the PLC backplane.
User scaling of programming units (User Units) in both Standard and Follower modes.
DSM314 firmware, stored in Flash memory, is updated via its front panel COMM port.
Firmware update kits provide firmware and Loader software on floppy disk. Firmware is also
available for download on the GE web site (http://www.ge-ip.com/support).
Recipe programming using command parameters as operands for Acceleration, Velocity,
Move, and Dwell Commands
Automatic Data Transfer between PLC tables and DSM314 without user programming
Ease of I/O connection with factory cables and terminal blocks
Electronic CAM capability, starting with Firmware Release (Version) 2.0
Control of GE α Series and β Series Digital servos, SL-Series servos, or third party
servos with analog velocity command or analog torque command interface.
Home and overtravel switch inputs for each Servo Axis
Two Position Capture Strobe Inputs for each axis can capture axis and/or master position with
an accuracy of +/-2 counts plus 10 microseconds of variance.
5V , 24V and analog I/O for use by PLC
Incremental Quadrature Encoder input on each axis for Encoder/Analog mode
Quadrature Encoder input for Follower Master axis
13 bit Analog Output can be controlled by PLC or used as Digital Servo Tuning monitor
High speed digital output (four each 24V and four each 5V) via on-board Local Logic control
