(4) Magnetic pole detection method using MR Configurator
The following shows the procedure of the magnetic pole detection using MR Configurator.
(a) Magnetic pole detection of the positioning detection method.
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 overcurrent alarm (32. )
and the setting value at the
occurrence of the magnetic pole
detection alarm (27. ).
Set parameter No.PS08 (Linear function selection 3) to " 0", and the magnetic pole detection
method to "position detection method".
YES
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.
NO
YES
YES
NO
NO
The magnetic pole detection operation is carried out.
Raise the value of parameter
No.PS09 in five.
End
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)
3)
Change to "Magnetic pole detection always valid" by setting the paramete No.PS01 (Linear function
selection 1) to " 1". (Note) 4)
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.
Execute the "positive direction travel" or "negative direction travel" with the "positioning operation" of
the MR Configrator test operation mode. Set the travel distance to "0" at this time. 7)
Is the parameter No.PS09
(Magnetic pole detection voltage
level) the final value?
Has the magnetic pole
detection alarm (27. ) occurred?
8)
Have the overload alarms
(50. and 51. ), overcurrent alarm
(32. ) and overload warning
(E1. ) occurred?
9)
Change to "Magnetic pole detection invalid" by setting the parameter No.PS01 (Linear function
selection 1) to " 0". (Note)
10)
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.
Note. When using an incremental type linear scale, the parameter No.PS01 setting is not required.
