Overview
The G-902 motion controllers offer a fully integrated electronics solution with controller and driver in a flat 19-inch rack mount housing. Integrated driver for up to 4 axes for the operation of positioners with different motor and encoder types, can be configured for a variety of applications. Ethernet velocity of up to 100 Mbps. Servo algorithms for advanced gantry and dual-loop control. Safety functions SS1 for safe braking and STO for switching off the power supply of the axes. 4 motor brakes via PWM brake driver, reduced heat generation of the motor brake.
Encoder
Supports incremental encoders (sine/cosine or RS-422) and, depending on the controller model, also absolute encoders (BiSS-C, EnDat 2.1 & 2.2, Smart-Abs, SSI, Sanyo-Denki, Panasonic A6). Depending on the application, the encoders can respectively be led to the motor interface or the separate sensor interface.
I/O lines
The digital inputs and outputs can be flexibly configured. For the evaluation of reference switches, digital inputs can alternatively be led to the motor connectors. Depending on the application, the inputs for the limit and reference switches can be configured for 5 V or 24 V and also as PNP or NPN inputs. Position synchronous trigger signals with up to 10 Mhz output frequency enable a precise process control at high travel velocities (position event generator – PEG).
Communication, software support
For communication with a PC, the motion controller is equipped with an Ethernet TCP/IP and an RS-232 interface. ACS SPii-Plus MMI Application Studio, a modern user software with tools for control tuning and visualizing is included in the scope of delivery. Programming libraries are available for C/C++, COM, .NET, and MATLAB.
Configuration
If the types of positioners used are specified when ordering, all connectors of the G-902 are suitably preconfigured at delivery. The default factory configuration, without positioner-specific adjustments, is detailed in the specifications. For subsequent adjustments, please contact our customer service department.
