5. OPERATION AND FUNCTIONS
POINT
Establish the machine configuration using the stroke limits (FLS and RLS). If the stroke limits (FLS
and RLS) do not exist, it may cause the machine damage by a collision.
At the magnetic pole detection, it is not predictable whether it moves to the positive direction or the
positive direction.
Setting the parameter No. PS09 (Magnetic pole detection voltage level) may cause the occurrence of
overload, overcurrent, magnetic pole detection alarm, etc.
When performing the positioning operation from the positioning controller, set the sequence which
confirms the normal completion of magnetic pole detection and the servo-on status, then outputs the
positioning command. If outputting the positioning command before the Ready (RD) turns ON, the
command may not be accepted or the servo alarm may occur.
After the magnetic pole detection, check the accuracy of position with the test operation (positioning
operation) of MR Configurator.
If a gap is generated to the positional relationship between the linear encoder and the linear servo
motor when using the absolute position linear encoder, carry out the magnetic pole detection again.
The accuracy of magnetic pole detection will be improved by being operated in the no-load condition.
The servo alarm may occur when the linear encoder is not mounted properly or when the setting
(parameter Nos. PS02 and PS03) of linear encoder resolution or the setting value of parameter No.
PS09 (magnetic detection voltage level) is not correct.
On the machine of which friction becomes 30% or more than the rated thrust, it may not operate
properly after the magnetic pole detection.
On the machine of which imbalance thrust becomes 20% or more than the rated thrust at the
horizontal axis, it may not operate properly after the magnetic pole detection.
