4.2.5 Magnetic pole detection method using MR Configurator
The following shows the procedure of the magnetic pole detection using MR Configurator.
(1) Magnetic pole detection using position detection method
Change to "Magnetic pole detection invalid" by setting the parameter No.PS01 (Special function
selection 1) to " 0". (Note)
Is the parameter No.PS09
(Magnetic pole detection
voltage level) the final value?
The magnetic pole detection is carried out.

Magnetic pole detection
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.
1)
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.
Set parameter No.PS08 (Special function selection 3) to " 0", and the magnetic pole detection
method to "position detection method".
Change to "Magnetic pole detection always valid" by setting the parameter No.PS01 (Special
function selection 1) to " 1". (Note)
Turn the power of servo amplifier off once and then turn it on again.
Set the parameter No.PS09 (Magnetic detection voltage level) to "F10" (guide value) as a guide.
Execute the "forward rotation" or "reverse rotation" with the "positioning operat" of the MR
Configrator test operation mode. Set the travel distance to "0" at this time.

Has the magnetic pole
detection alarm (27) occurred?
Have the overload alarms (50 and
51), overcurrent alarm (32) and
overload warning (E1) occurred?
8)
End
YES
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).
Reset the alarm or turn the power
of servo amplifier off once, and
then turn the power on again.
Turn the power of servo amplifier
off once and then turn it on again.
Reset the alarm or turn the power
of servo amplifier off, and then turn
the power on again.
Raise the value of parameter
No.PS09 in five.
Note. Parameter No.PS01 setting is unnecessary for an incremental system.
