15. USING A LINEAR SERVO MOTOR
15 - 16
3) Linear servo motor movement (when LSP (Forward rotation stroke end) or LSN (Reverse rotation
stroke end) is off)
When LSP or LSN is off at servo-on, the magnetic pole detection is carried out as follows.
LSN
LSP
(Note)
Magnetic pole detection completion position
Magnetic pole detection
start position
Servo-on
position
The linear servo motor moves to a
magnetic pole detection start position
upon servo-on, and the magnetic pole
detection is executed.
The linear servo motor reciprocates several times and returns
to the magnetic pole detection start position to complete the
magnetic pole detection and to go into the servo-lock status.
At this time, there may be a gap, approximately a quarter of
the pitch against magnetic pole, from the start position.
Note. For the pitch against magnetic pole, refer to (2) (a) 2) Note 2 in this section.
(b) For the absolute position linear encoder
POINT
The magnetic pole detection is required at the following timing.
When the system is set up (at the first startup of equipment)
After a servo amplifier is replaced
After a linear servo motor (primary-side or secondary-side) is replaced
After a linear encoder (scale or head) is replaced or remounted
If a gap is generated to the positional relation between the linear encoder and
the linear servo motor, perform the magnetic pole detection again.
Perform the magnetic pole detection in the following procedure.
1) Set [Pr. PL01 Linear servo motor/DD motor function selection 1] to "_ _ _ 1" (Magnetic pole
detection at first servo-on).
[Pr. PL01]
Magnetic pole detection at first servo-on (Initial value)
1
2) Execute the magnetic pole detection. (Refer to (2) (a) in this section.)
