The synchronous parameter " [Pr.437]
Speed change ratio: Denominator" is
set to 0 or lower"
The synchronous parameter " [Pr.435]
Speed change gear smoothing time
constant" is set other than 0 to 5000.
Overflow (sign reversion) occurred in
input values, because the speed
change ratio of speed change gear is
too large.
The synchronous parameter " [Pr.440]
Cam No." is set to other than 0 to 256.
Cam data specified in the synchronous
parameter " [Pr.440] Cam No." does not
exist on the cam open area.
The synchronous parameter " [Pr.439]
Cam axis length per cycle" is set to 0 or
lower.
The synchronous parameter " [Pr.447]
Output axis smoothing time constant" is
set to other than 0 to 5000.
The synchronous parameter " [Pr.460]
Setting method of current value per
cycle after main shaft gear" is set to
other than 0 to 2.
The synchronous parameter " [Pr.465]
Current value per cycle after main shaft
gear (Initial setting)" is other than 0 to
(Cam axis length per cycle -1).
The synchronous parameter " [Pr.461]
Setting method of current value per

• The synchronous parameter " [Pr.464]
Setting method of cam axis current
value per cycle" is set to other than 0
