(5) Magnetic pole detection method by using MR Configurator
The following shows the magnetic pole detection procedure by using MR Configurator.
(a) Magnetic pole detection by the position detection method
Magnetic pole detection
1) After confirming that the stroke limits (FLS and RLS) and the forced stop (EM1) are on, turn the
power of servo amplifier off once and then turn it on again.
2) After switching the test operation select switch (SW2-1) of the servo amplifier to "Up", turn the power
of servo amplifier off once and then turn it on again.
3) Set parameter No.PS08 (Special function selection 3) to "
method to "position detection method".
Change to "Magnetic pole detection always valid" by setting the parameter No.PS01 (Special

function selection 1) to "
5) Turn the power of servo amplifier off once and then turn it on again.
6)
Set the parameter No.PS09 (Magnetic detection voltage level) to "F10" (guide value) as a guide.
7) Execute the "forward rotation" or "reverse rotation" with the "positioning operat" of the MR
Configurator test operation mode. Set the travel distance to "0" at this time.
The magnetic pole detection is carried out.
Is the parameter No.PS09
YES
(Magnetic pole detection

Has the magnetic pole
detection alarm (27) occurred?
Have the overload alarms (50 and
51), overcurrent alarm (32) and
overload warning (E1) occurred?
8) Change to "Magnetic pole detection invalid" by setting the parameter No.PS01 (Special function
selection 1) to "

Raise the value of parameter
No.PS09 in five.
Set approximately 70 of the
parameter No.PS09 as the final
setting vale.
In the case where the magnetic pole
detection error (27) occurs with this
setting value, set the final setting
value to the value intermediate
between the setting value at the
occurrence of the overload alarms
(50 and 51), overcurrent alarm (32),
overload warning (E1) and the setting
value at the occurrence of the
magnetic pole detection alarm (27).
