	Description Simulated encoder output on a 9-pin female D-type
		connector

This output can be used for master slave situations where the axis movement can be transmitted to another controller or MintDrive. It is recommended that this output only drives one output circuit load. Driving multiple loads is not recommended. The encoder outputs are differential and conform to the RS422 electrical specification. Shielded twisted pair cable is recommended.

If a resolver is fitted to the MintDrive, the output resolution is 1024 ppr (pulses per revolution). This is equivalent to a 1024 line encoder, giving 4096 quadrature counts per rev. The simulated encoder also supports an index or marker pulse.

If the MintDrive has the encoder feedback option, X3 duplicates the encoder signals entering X2.

CAUTION: Using connectors X3 and X6, multiple MintDrives can be ‘daisy-chained‘ together. However, if another Mint based controller such as a NextMoveBX is to be connected, a special cable must be built, as shown below:
