Example of input:
At a production machine the access to the work zone for manual insert or rather, manual setting
shall be released for certain positions of the main input axis. The drive remains in this position and
is only monitored for standstill. The limits of the expansion stroke are variable and shall be
monitored in an electronically safety-relevant way. The active movement to be monitored is a linear
movement. An absolute encoder isdirectly interlocked with the main feed axis as a linear path
measurement system. The main axis is the referential axis for the SCU unit.
1. Range selection
With the position monitor the position of the main axis in the upper zero point shall be monitored.
The upper zero is also the referential zero point in the length measuring device of the feed axis. If
the range is recognised, one protective device is released for opening.
Limit range X1 = upper position = 0 mm
Limit range X2 = lower tolerance limit for position = 2 mm
Speed = tolerated speed for conservation of position
Acceleration = tolerated speed for conservaion of positioning der Position = 5 mm/s
