IMPORTANT! It is essential that the 6A and 9A models receive additional cooling, as stated in the installation manual. Air should originate from below the MicroFlex, passing parallel to the heatsink. Optional fan tray
FAN001-024 provides sufficient cooling for all models.

* If using incremental encoder feedback, X7 duplicates the input on connector X8.
* If using resolver feedback, X7 creates a simulated encoder output.
* If using SSI encoder feedback, X7 creates simulated encoder output bursts representing change of position.
* If using Halls-only feedback, no output is produced.
