Since the axis must be moved in order to identify and set the control loop,
it is necessary to define an allowed travel range. There are basically two
possibilities for defining the range within which the axis may move during
the automatic control loop setting:
•
definition of a travel range by entering limit values in the parameters
P-0-0166 and P-0-0167
- or -
•
definition of a travel range by parameterizing
P-0-0169, Travel
distance for autom. control loop adjust
(required for modulo axes)
Note:
The mode for travel range definition is selected in parameter
P-0-0165, Selection for autom. control loop adjust
(bit 15).
If bit 15 of P-0-0165 has not been set (value "0"), the allowed travel range
is defined by means of
•
the lower limit position (P-0-0166) and
•
the upper limit position (P-0-0167).
The value of
P-0-0169, Travel distance for autom. control loop adjust
results from these two limit values.
If bit 15 of P-0-0165 has set (value "1"), the allowed travel range is
defined by means of
•
P-0-0169, Travel distance for autom. controller adjust
and
•
start position
(actual position) at the start of the command.
The resulting limit values for the travel distance are:
•
lower limit: P-0-0166 = start position – 0.5*travel distance (P-0-0169)
•
upper limit: P-0-0167 = start po0.5*travel distance (P-0-0169)
