4-10 Input / Output MN19024.4 Other I/O4.4.1 Encoder output - X7Location Connector X7Pin Name1 CHA+2 CHB+3 CHZ+4 (NC)5 DGND6 CHA-7 CHB-8 CHZ-9 (NC)Description Encoder output on a 9-pin female D-type connectorThis output can be used for position feedback to a host positioner, or in master/slave situationswhere the axis movement can be transmitted to another controller or FlexDriveII. It isrecommended that this output only drives one output circuit load. The encoder outputs aredifferential and conform to the RS422 electrical specification. Shielded twisted pair cable isrecommended.If the resolver feedback option is fitted, a simulated encoder output is produced at X7. If theresolver input has been configured to simulate an encoder input of 1024 pulses per revolution(ppr), the output at X7 can be set to either 512 or 1024 ppr. If the resolver input has beenconfigured to simulate an encoder input of 4096 ppr, output modes of 512, 1024, 2048 and4096 ppr are possible. Note that these values represent actual encoder lines, not quadraturecounts. See the keyword ENCODERLINESOUT in the Mint help file.If the basic encoder feedback option is fitted, X7 duplicates the encoder signals entering X8.If the EnDat (absolute encoder) feedback option is fitted, a simulated encoder output isproduced at X7. The output ppr is equal to the number of Sin/Cos cycles of the absoluteencoder. For example, if a 2048 cycle absolute encoder is connected, the output at X7 will beequivalent to a 2048 ppr encoder. Note that this value represents actual encoder lines, notquadrature counts.The encoder output supports an index or marker pulseCAUTION: Using connectors X7 and X8, multiple FlexDriveII units can beëdaisy-chainedí together. However, if another Mint based controller suchas a NextMoveBX is to be connected, a special cable must be built, asshown in Figure 29:1569
