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 the linear encoder resolution used to the parameter Nos. PS02 and PS03
(Linear encoder resolution setting).
4) Change to “Magnetic pole detection always valid” by setting the parameter
No. PS01 (Linear function selection 1) to " 1".
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 “10” (guide value) as a guide.
7) Execute the “forward rotation” or “reverse rotation” with the “positioning operation”
of the MR Configrator test operation mode. Set the travel to “0” at this time.
The magnetic pole detection operation is carried out.
Is the parameter No. PS09
(Magnetic pole detection
voltage level) the final value?
8) Has the magnetic pole
detection alarm (27) occurred?
9) Have the overload alarms
(50 and 51), overcurrent alarm (32) and
overload warning (E1) occurred?
End
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.
Set 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).
What is the linear scale type?
Absolute position
10) Change to “Magnetic pole detection invalid” by setting the parameter No.PS01
(Linear function selection 1) to " 0"
