Software Setup and Operation
Figure 86: Velocity vs. Time Profile of a Feed Sensor Index
There are two different sensor inputs available; Feed Sensor Ø and Feed Sensor 1. This type
of index can also be setup as a Feed to Torque index where the FX drive will accelerate to a
percent of continuous Torque on the motor instead of looking for a sensor input.
The Feed Sensor Limit Hit output function (output function number 10) if assigned, will turn
on an output line as a warning you that this limit has been exceeded. However, this function
is not a fault condition, only a warning. If the Feed Sensor Limit Distance is exceeded, the
output will come on and the drive will decel to zero similar to a normal end of an index
operation.
Registration Index
A Registration Index is used in applications where the motor must move until an object is
detected and then move a specific distance from the point of detection, such as finding a
registration mark and moving a distance beyond.
The Registration Index consists of two parts. The first part accelerates the motor to the feed
velocity. At this point the drive will continue at this velocity until it receives a sensor input.
Upon receipt of a sensor input, the index portion will be executed. A Feed Sensor Limit
Distance can be programmed to turn on an output (Sensor Limit Distance Hit) if a sensor input
or torque limit is not received within the Limit Distance.
