16.3.4 Testing the direction of traverse
Test the controls for the direction of traverse according to the following diagram (effective machine
parameters: MP210 count direction of the measuring system signals, MP1040 polarity of the
nominal value voltage, MP1320 direction of traverse on passing over the reference marks).

?
(both ref.
approach
modes must
be run!)
Is
direction of
traverse of axes
correct? (determined
by MP1040 and
MP210)
Was
"gross positioning
error"
or
direction of traverse
wrong or direction
traverse wrong when
approaching
ref. marks
?
Switch on line voltage
START
Reset current interruption with CE
Switch on control voltage:
axes are in control loop
Gross "positioning
error" (MP1040
or MP210 wrong)

Is
direction of
traverse correct?

Ref. approach
with start key
Check direction of traverse of
ref. approach for all axes Check direction of traverse
for all axes
This flow diagram must be worked through for every axis!
