(3) For activating phase measurement, set the parameter below.
1726 (FS15i)
Parameter for internal data measurement
2115 (FS16i)
Series 9096:
326 for an odd-numbered axis and 966 for an even-numbered axis
Series 90B0, 90B1, 90B5, or 90B6:
326 for an odd-numbered axis and 2374 for an even-numbered axis
Under this condition, the activating phase is output from CH1 on the
check board.
To use a digital check board to measure data with a personal computer,
set up "SD" (servo tuning software) as stated below. The displayed
value is in degree units ("360 degrees" is displayed as "360").
DOS prompt > SD INIT [Enter]
o (Origin of position)
F9 (System setting)
0 (CH0)
2 [Enter] (TCMD)
639.84375 [Enter] (A)
F10 (Return to main menu.)
* See Sec. 4.19 for explanations about how to use the SD software.
In addition, the analog voltage from the check board can be
observed using an oscilloscope. In output conversion, 2.5 V
corresponds to 360 degrees.
(4) The procedure for measuring the activating phase is the same as
when SERVO GUIDE is used.
(5) After completing the adjustment, reset to 0 the parameter set in
step (3).
Absolute type
The procedure for AMR offset adjustment when an absolute type
linear encoder is used is described below. When using an incremental
type linear encoder, see the item of Incremental type described earlier.
Make a fine activating phase adjustment according to the procedure
below.
CAUTION
In this adjustment, the linear motor is driven by
current fed from the DC power supply. So, the CNC
does not exercise position control. For safety,
move the coil slider of the linear motor to near the
stroke center and make an adjustment. (Activation
by the DC power supply moves a medium-size or
large linear motor for up to about 60 mm, and
moves a small linear motor for up to about 30 mm.)
