The IC693DSM302 motion controller is a high-performance Series
90-30 motion controller manufactured by GE Fanuc. Designed for
seamless integration with PLC components from the same series, this
controller delivers advanced motion control capabilities for
industrial automation and machine control applications. With 2-axis
control, it effectively resolves communication and operational
challenges between system components.
This controller is specifically engineered for controlling GE
digital servo motors and features an integrated digital signal
processor that outperforms comparable controllers from other
manufacturers. It also supports SL Series analog servos and
third-party analog servos. The unit requires minimal programming
effort and accommodates external programming devices through its
built-in RS-232 serial port, which also facilitates firmware
updates.
Performance Specifications
The GE Series 90-30 IC693DSM302 motion controller boasts an
impressive short block processing time of less than 5 milliseconds.
Programming units feature the following parameters:
- Positioning: -8,388,608 to 8,388,607 user units per second
- Velocity: 1 to 8,388,607 user units per second
- Acceleration: 1 to 134,217,727 user units per second
The controller includes a comprehensive instruction set that
enables users to maximize all available functions and provides
non-volatile storage capacity for up to 10 programs and 40
subroutines.
