Universal driver module

ACS driver module for the operation of positioners with different motor and encoder types, can be configured for a variety of applications. 4 axes, 5 A continuous current per axis possible. 4 motor brakes via PWM brake driver, reduced heat generation by the motor brake. Motion profiles are generated by an external motion controller (not included) and received via EtherCAT.

Encoder

Supports incremental encoders (sine/cosine or RS-422) and absolute encoders (BiSS-C, EnDat 2.1 & 2.2, Smart-Abs, SSI, Sanyo-Denki, Panasonic A6). Depending on the application, encoders can be connected to the motor interface or separate sensor interface.

I/O lines

Digital inputs and outputs can be flexibly configured. To evaluate reference switches, digital inputs can alternatively be routed to motor connectors. Depending on the application, inputs for 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 precise process control at high travel velocities (position event generator – PEG).

Communication

Communication with a PC via Ethernet TCP/IP and RS-232 interfaces. EtherCAT interface for integration with an EtherCAT network. Commanding via an EtherCAT master.

Configuration

If the types of positioners used are specified when ordering, all connectors of the G-902 are suitably preconfigured at delivery. The default configuration, without positioner-specific adjustments, is detailed in the specifications. For any subsequent adjustments, contact PI customer service.
