2.5. Auxiliary I/O Connector
2.5.1.1. Square Wave Encoder
The drive accepts RS-422 square wave encoder signals. The drive will generate a feedback fault if it
detects an invalid signal state caused by an open or shorted signal connection. Use twisted-pair wiring
for the highest performance and noise immunity.
