14. USING A DIRECT DRIVE MOTOR
14 - 16
(b) Absolute position detection system
POINT
Turn on the Z-phase pulse of the direct drive motor in JOG operation after the
magnetic pole detection.
Perform the magnetic pole detection in the following procedure.
1) Set parameter No.PS01 (Special function selection 1) to "
1 (Magnetic pole detection
enabled)".
1
Magnetic pole detection always valid (initial value)
Parameter No.PS01
2) Execute the magnetic pole detection. (Refer to (2) (a) 1) and 2) of this section.)
3) After the completion of the magnetic pole detection, change Parameter No.PS01 to "
0
(Magnetic pole detection disabled)".
0
Magnetic pole detection invalid
Parameter No.PS01
After the magnetic pole detection, by turning on the Z-phase pulse of the direct drive motor in JOG
operation and by disabling the magnetic pole detection function with Parameter No.PS01, the
magnetic pole detection after each power-on is not required.
(3) Magnetic pole detection method setting
Set the magnetic pole detection method using the first digit of parameter No.PS08 (Magnetic pole detection
method selection).
Method selection for the magnetic pole detection
0: Position detection method
4: Minute position detection method
Parameter No.PS08
