5. OPERATION AND FUNCTIONS
(b) Magnetic pole detection flow
The magnetic pole detection by the current detection 1 is shown using the flow chart below.

Does the overload 1 (50)
or overload 2 (51) occur?
Does it oscillate during
the magnetic pole detection?
End
Make Parameter No. PS09 (Magnetic pole detection voltage level)
smaller five by five.
or
Make Parameter No. PS11 (Current detection method oscillation setting)
smaller 10 by 10.
Lower the response level (Parameter No. PA09) of the auto tuning.
or
Use the machine resonance filter (Parameter Nos. PB13 and PB15).
Is the gain adjustment completed?
Is the load mass ratio
(calculated value)against the linear servo
motor primary side known?
Change to the manual mode 2
(Parameter No. PA08: 2)
and set the load mass ratio (calculated value)
against the linear servo motor primary side.
Perform the gain adjustment after the
magnetic pole detection by th
positioning detection method.
Perform the magnetic pole detection.
Does the initial magnetic
pole detection error (27) occur?
Check the following parameters:
Parameter No. PS09 (Magnetic pole detection voltage level)
Parameter No. PC27 (Encoder pulse count polarity)
Parameter Nos. PS02 and PS03 (Linear encoder resolution setting)
(2) Magnetic pole detection by the current detection 2
For the positioning detection method 1 and current detection method 1, this method is used in the machine
configuration with little friction such as an air guide when the magnetic pole detection cannot be completed
normally. The setting method is the same as that of the current detection method 1, but there is a possibility
that it moves a half distance of the maximum magnetic pole pitch at the magnetic pole detection.
