This registry entry enables support of direction flags with Firmware Distributed Controller (FDC) rotary tables.
Full support of the direction flags on FDC rotary tables requires that EnableRotaryAbsolutePosition also be set to TRUE (the default setting).
Entry Name: EnableRotaryClockMode
Entry Type: If set to TRUE (the default), it enables FDC rotary tables to cross the 0 and 360 degree positions. You can use this with the EnableRotaryClockMode registry entry. If that entry is also TRUE, the properties for SHORTEST, CW, and CCW through the 0 and 360 positions are allowed.
If the value is FALSE, the rotary will not support direction flags, and it will not make a move through the 0 degree position. Instead, it will move in the opposite direction to reach the destination.
It is recommended that for FDC rotary tables, the EnableRotaryAbsolutePosition and EnableRotaryClockMode registry entries should both be set to TRUE.
Do not change these settings. Refer to the Machine Interface Installation Manual (MIIM) help file for detailed information.
