SC Series Controllers
Configuration
Yield Target:
The falling slope rate at which the controller shuts off the tool. Yield target is a percentage (0%-100%) of change
(decreasing slope) from the peak rate. The falling slope rate units are the selected torque units/degrees of
rotation.
Max Torque:
A combination of the High Torque and Bailout on High Torque parameters. Used in Angle Control Smart Steps
only.
Position Target:
The number of degrees from Tool Zero Position where the controller will shut off the tool during a Position
Control / Torque Monitor strategy after achieving Snug Torque.
Wobble:
Creates a Smart Step with the strategy that rotates the fastener in the opposite direction as the Audit step is
programmed. The fastener threads align with the locking device threads before standard forward rotation and
high speed are applied (prevents cross-threads). If selected, this is the first step in the tool strategy.
Slow Seek:
Creates a Smart Step with the strategy that rotates the fastener in the same direction as the Audit step is
programmed. The flats of the socket align with the flats on the fastener before standard forward rotation and
high speed are applied. Using Slow Seek as a first step also allows for cross-thread and re-hit detection. If
selected, this is the first step AFTER Wobble.
Self Tap:
In some fastening situations, the initial fastening cycle torque is as high as or higher than the target torque
specification limit for the joint. In other cases, such as thread rolling or forming, overcoming friction in getting the
fastener started causes the high initial torque. In order to compensate for this high initial torque, the Self Tap
control allows the controller to drive the tool for a specified amount of angle at the start of a fastening cycle.
Creates a Smart Step with the strategy in the same direction as the Audit step is programmed. If selected, this is
the first step AFTER Slow Seek.
Condition:
Creates two Smart Steps before the Audit step. The first step is the strategy that rotates the fastener in the
same direction as the Audit step is programmed. This runs a fastener down to an initial torque level. The second
is a Back off strategy which partially removes the fastener.
The purpose of this procedure is to polish the threads and reduce friction variation during the Audit step. This
ensures more consistent results. If selected, this is the first step AFTER Self Tap and Pre-Torque.
