G-910.RC03: ACS UDMnt power amplifier in control cabinet housing

Universal driver module

ACS driver module for operation of positioners with different motor and encoder types, can be configured for a variety of applications. 2 axes, 5 A continuous current per axis possible. 2 motor brakes via PWM brake driver, reduced heat generation by the motor brake. Motion profiles are generated by an external motion controller, e.g., G-910.RC02, and received via EtherCAT. The motion controller must be ordered separately.

Housing types

Available as a benchtop device or a control cabinet module; the adapter for mounting on a TH-35 top hat rail or a mounting plate is included in the scope of delivery for the control cabinet version.

Encoder

Supports incremental encoders (sine/cosine or RS-422) and absolute encoders (EnDat 2.2 & 2.1, Smart-Abs, Panasonic, BiSS-A/B/C (SSI)). 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

EtherCAT interface for integration with an ACS EtherCAT network. Commanding via the G-910.RC02 motion controller, for example, which integrates an SPiiPlusEC controller + EtherCAT master from ACS, among other components.

Configuration

If the types of positioners used are specified when ordering, all connectors of the G-910.RC01 / G-910.RC03 are suitably preconfigured at delivery. The default configuration, without positioner-specific adjustments, is detailed in the specifications. For subsequent adjustments, contact PI customer service.
