Parameter P213: direction of machine zero
(this describes the default setting, for more information see Page 80
Standard reference system: no end or reversing initiators; one machine zero
initiator at the end of the displacement area
The machine zero initiator must be attached so that it can only cleared in one
direction; i.e. attached to one side.
Use parameter P213 to inform COMPAX of the side on which the MZ
13
(machine
zero) initiator is attached.
The machine zero initiator is approached with the motor turning clockwise (when
facing the motor shaft).
The machine zero initiator is approached with the motor turning anti-clockwise.
Set P215="0":
Actuate Hand+; the drive moves in the direction of the MZ initiator, then the
following applies: P213="0", if this is not the case, set P213="1".
The following basic setting applies for this standard reference system (
≡
no
end or reversing initiators; one machine zero initiator at the end of the
displacement area): P212="1", P217="0", P216="0". You will find other
options for defining a reference system in the next chapter.
Specify the software end limits of the displacement area by using parameters P11
and P12. Each time a positioning command is issued, COMPAX checks whether
the target is within the travel distance. If this is not the case, error E25 is reported.
When working in continuous mode, these limits always apply for the current
positioning process.
Range:
±
4 000 000 [units corresp. P90]
Range:
±
4 000 000 [units corresp. P90]
Absolute positioning commands refer to RZ.
RZ is specified relative to machine zero.
P1 must be set to 0 in continuous mode .
Range:
±
4 000 000 [units corresp. P90]
P215 establishes the positive direction of travel (positive end of displacement area)
referenced to the motor direction of rotation.
P215="0" the motor is turning clockwise when traveling in the positive direction
P215="1" the motor is turning anti-clockwise when traveling in the positive
direction
♦
Clockwise means when looking at the motor shaft.
Proceed with Hand+; the motor must move in the direction which is defined as
being the positive direction. If this is not the case, then P215 must be modified.
P215 has no influence on the setting of the machine zero direction (P213); if
it has the same mechanical design.
