MOTOROLA MVME147-013A Digital I/O module

The encoder output signals from the drive should be connected to the encoder input on each axis. The MMC analog section accepts RS422 level differential inputs. The encoder signals should be quadrature type. All encoder wiring between the MMC and the drive should be shielded twisted pair. NOTE: The encoder input on the auxiliary connector is identical to the encoder inputs on the axis connectors

Auxiliary I/O Connector 

The auxiliary I/O 44-pin connector provides the following inputs: • One quadrature, incremental encoder channel (1 Mhz frequency, RS422 interface) 

• Five fast DC inputs (one per encoder input) for high speed position latching) • One 12-bit resolution analog input channel 

• 12 optically isolated DC inputs 

• +24 VDC output • +5 VDC output 

• Seven Shields The auxiliary I/O connector pinout for the MMC-A4 (4 axes) is listed below.
