TRACKINGMODE

Tracking Motion

Purpose Set the directional gearing mode of the Tracking function.

Syntax TRACKINGMODE = n

variable = TRACKINGMODE

nn specifies which of the modes to set. Values for n are 0 through

variable Value can be a nonvolatile variable Gn, a volatile variable Vn, or

another system variable.

Remarks Mode 0 is normal gearing.

Mode 1 is when any forward motion of the master results in forward follower motion,

much like a ratchet.

Mode 2 is similar to mode 1 except if the master moves in reverse, then forward again,

the follower will not move until the master returns to the position where it began mov-

ing reverse.

TRACKINGSYNCED

Tracking

System

Purpose ON indicates the Tracking function is not limiting gearing motion.

Syntax variable = TRACKINGSYNCED

variable Variable can be a nonvolatile flag Bn, a volatile flag Fn, or

another system flag.

Remarks If this flag is off, the master has backed up and the tracking function is limiting fol-

lower motion.
