Magnetic pole detection time (Note)
Note. The magnetic pole detection time indicates the operation time when LSP (Forward
rotation stroke end) and LSN (Reverse rotation stroke end) are on.
2) Direct drive motor movement (when LSP or LSN are on)
Magnetic pole detection completion position
Servo-on position (Magnetic pole detection start position)
Center of direct drive motor rotation part
LSP (Note)
(Note) LSN
10 degrees or less
Note. When the stroke limit (LSP or LSN) is turned off during the magnetic pole detection,
the magnetic pole detection is carried on to the opposite direction. When LSP and
LSN are off, [AL. 27 Initial magnetic pole detection error] occurs.
3) Direct drive motor movement (when LSP or LSN is off)
When LSP or LSN is off at servo-on, the magnetic pole detection is carried out as follows.
Magnetic pole detection completion position
Magnetic pole detection
start position
After the machine moves to the position where the stroke limit
(LSP or LSN) is set, the magnetic pole detection starts.
