Direction Of Traverse - HEIDENHAIN iTNC 530 Technical Manual

Direction of
traverse
February 2002
With MP210 and MP1040 you define the direction of traverse of the axes. The
counting direction depends on the position in which the encoders are
mounted. Configuration errors in these parameters provoke the error message
MOVEMENT MONITORING ERROR IN <AXIS.> Through W1030 the NC informs the
PLC of the direction in which the axes traverse.
If the speed encoder is also used for position measurement, MP210 must be
set for the speed encoder. Configuration errors in these parameters provoke
the error message standstill monitoring <in axis>.
MP210 Counting direction of position encoder output signals
Format: %xxxxxxxxxxxxxx
Input: Bits 0 to 13 correspond to axes 1 to 14
0: Positive
1: Negative
MP1040 Analog axes: Polarity of nominal value voltage
Digital axes: Algebraic sign of the nominal speed value
Format: %xxxxxxxxxxxxxx
Input: Bits 0 to 13 correspond to axes 1 to 14
0: Positive
1: Negative
W1030 Current direction of traverse
Bits 0 to 8 correspond to axes 1 to 9
0: Positive traverse direction
1: Negative traverse direction
Note
The counting direction of the speed encoder signals is defined in the motor
table (DIR column). If the error message C3B0 Motor <AXIS> does
not rotate appears, you must change this entry.
