Fuji FALDIC-β Servo Drive
01 Command Pulse Numerator α, 02 Command Pulse Denominator β
Equal to numerator/denominator of electronic gear ratio.
Calculation formula: **α/β = (Encoder resolution * Pulse equivalent * Mechanical
reducer ratio)/ Screw pitch
Example: encoder resolution 65536, pitch 5mm, pulse equivalent 0.001, mechanical
reducer ratio 1, α/β=65536×0.001/5=8192/625. Thus, α=8192, β=625.
Range: [1, 32767]
Set value: to be calculated.
03 Pulse String Input Form
Set the input mode of pulse string as: instruction + symbol, that is “pulse +
direction”.
Set value: 0
04 Direction of Rotation Switch
Set as 0: positive direction: forward rotation (CCW)
Set as 1: positive direction: reverse rotation (CW)
Set value: 0/1
10 CONT1 Signal Distribution
Set as 1: CONT1 is distributed as RUN (i.e. SON); if not distributed, CONT1 will be
auto ON if there is no alarming when powered.
Set value: 1
11 CONT2 Signal Distribution
Set as 2: CONT2 is distributed as RST (i.e. servo alarming clearance CLR). When 12,
13, 14 are 0, that is CONT3, CONT4 and CONT5 cannot be distributed as OT over-
travel or EMG (external emergency stop).
Set value: 2
15 OUT1 Signal Distribution
Set as 1: OUT1 is distributed as a-contact point of alarming output.
Set as 2: OUT1 is distributed as b-contact point of alarming detection.
Set value: 1
