4. OPERATION AND FUNCTIONS
4 - 5
(2) For the absolute position detection system
POINT
Be sure to turn on the Z-phase pulse in JOG operation after the magnetic pole
detection.
Carry out the magnetic pole detection referring the following procedure.
(a) Set the parameter No.PS01 (Special function selection 1) to "
1 (Magnetic pole detection always
valid)".
1
Magnetic pole detection always valid (initial value)
Parameter No.PS01
(b) Execute the magnetic pole detection. (Refer to (1) (a) and (b) in this section)
(c) Change the parameter No.PS01 to "
0 (Magnetic pole detection not valid)" after the normal
completion of magnetic pole detection.
0
Magnetic pole detection invalid
Parameter No.PS01
By turning on the Z-phase pulse in JOG operation and by making the magnetic pole detection function
invalid with the parameter No.PS01 after the magnetic pole detection, the magnetic pole detection for
each power-on will be unnecessary.
