Description of functions by means of an example
With the function “ramp function generator for phase signals” the drive can be moved by a defined
distance compared to the master drive. It must be determined whether the drive reaches the target
position with a predefined speed (-T/DIST = LOW)or - depending on the master drive speed - after
a certain distance (-T/DIST = HIGH).
Example: The drive is to be moved by 5 m-units starting with the 0 position of the profile. The
controller is enabled via terminal X5/E1.
Masterunits (m-units)canmeasureddirectlyinthesystemattheobjecttobemoved.Possiblearemm,
m, phases, etc. Referred to the motor, these actual values become slave units (s-units). The controller
converts the s-units into encoder increments.
