Start-Up
* 2: single-edge evaluation, for locking the reference point in the rising edge of
the proximity switch; 4: double-edge evaluation, for locking the referece point
in the intermediate point between rising and falling eges.
Notice
Even if the function “record reference point” has been activated, reference
point must be approached again under following circustances, otherwise
collision might be resulted!
1. After system power up with saved data
a
）
After machine operator selects on the operator panel to
“
power up with
saved data
”
(corresponding alarm# 004062).
b
）
System will be powered up automatically with saved data after it has been
dead for a long period and battery for internal data savings run out of
power. (corresponding alarm# 004065)
2. After system power-off, the actual position of the axis concerned has
been moved out of maintenance or other reasons.

Note:
After determining the mechanical parameters,
set the axis speed. For
stepper motors, the motor speed shall be determined according to its
frequency-torque characteristics: motor speed
＝
axis speed/leadscrew
