HEIDENHAIN MANUALPLUS 620 - 6.4.6 Defining the traverse direction

January 2012 6.4 Encoders 663
6.4.6 Defining the traverse direction
The parameter object CfgAxisHardware is not required for:
 Virtual axes (MP_axisMode=Virtual)
When using the CC 61xx, define the counting directions and the traverse
direction of the axis, depending on the mounting attitude of the encoders.

Signal Parameter Entry / Effect
A MP_signCorrActualVal Invert the value if the counting direction
of the position encoder is opposite to the
direction of rotation of the motor.
B MP_signCorrNominalVal Changing the value inverts the nominal
and actual values of the position
encoder. The axis changes the traverse
direction.
