3.4.1.1.7 Fuji ALPHA 5
The parameters and descriptions are shown below:
PA1_01 Control mode selection
o Description: PA1_01 control mode selection
o Unit: -
o Range
0: Position control.
1: Velocity control.
o Value: 0
PA1_06 Electronic gear ratio numerator 0, PA1_07 Electronic gear ratio
denominator
o Description: Relation between PA1_06 and PA1_07
o Unit: -
o Range: 1–32767
o Equation: PA1_06/PA1_07 =(Encoder resolution × pulse equivalent ×
mechanical reduction ratio)/screw pitch
o Value: When encoder resolution = 65536, pulse equivalent = 0.001, screw
pitch = 5 mm, and mechanical reduction ratio = 1: PA1_06/PA1_07
=65536×0.001/5=8192/625. Therefore, PA1_06 = 8192 and PA1_07 = 625.
PA1_03 Command pulse format
o Description: PA1_03 command pulse format
o Unit: -
o Range: 0: The pulse train input format is pulse + direction (symbol), negative
logic.
o Value: 0
PA1_04 Rotation direction
o Description: Rotation direction
o Unit: -
o Range
0: Rotates CW (anti-clockwise when observing from the load side)
1: Rotates CCW (clockwise when observing from the load side)
o Value: 0 or 1
PA3_01 CONT1 signal distribution
o Description:CONT1 signal distribution
o Unit: -
o Range: 1: CONT1 is distributed to RUN (SON). If CONT1 is not distributed, it
becomes ON if there is no alarm after power-on.
o Value: 1
PA3_02 CONT2 signal distribution
