(2) Weight of override
The weight can be changed, using PA2_36 to 39 (override 1/2/4/8).

PA2_37 Override 2 20
PA2_38 Override 4 40
PA2_39 Override 8 80
If all the override 1/2/4/8 settings are turned on, the weight is 150 (10 + 20 + 40 + 80). If the sum
exceeds 150, the value immediately before is retained.
(3) Maximum rotation speed
Use the setting of PA1_25 (max. rotation speed (for position and speed control)) to specify the
maximum rotation speed of the output shaft. However, the setting is disabled for command pulse
inputs.
Interrupt input enable: Sequence input signal (Reference value 48)
Interrupt input: Sequence input signal (Reference value 49)
Use to realize the interrupt positioning function.
This signal is enabled only when parameter PA1_01 (control mode selection) is set to "6" (extension
mode) or "7" (positioning function).
 Function
If the interrupt input enable signal assigned to a CONT input signal is turned on, stoppage is
caused after a travel of a certain amount since the interrupt input signal is turned on.
Specify the traveling amount after the interrupt input in PA2_20 (interrupt traveling unit amount).
The rotation speed is based on the X1, X2, and X3 signals, or the input voltage to the speed
command [VREF] terminal.
The rotation speed after an interrupt input keeps the speed at the rising edge effective.
The override is enabled even after the rising edge.
To change the rotation speed in the interrupt positioning mode, use the override.
 Parameter setting
To assign the interrupt enable to a sequence input terminal, specify the corresponding value ("48")
to the input terminal function setting parameter. For the interrupt input, specify ("49").
These signals are handled to be always turned off if they are not assigned to sequence input
terminals.
