Description
ting
Sets the distance from the latch signal input
position to the origin when performing origin
return.
The operation after detecting the latch signal
input position will be determined by the origin
return direction and this parameter as follows.
Origin Sign
return
Positive
direction
Moves in the
Positive positive
direction direction and
*1
stops
Moves in the
Negative negative
direction direction and
*1
stops
*1. Reverses after decelerating to a stop if
the final distance for origin return is short
in comparison to the deceleration
distance.
Sets the numerator for the electronic gear ra-
tio.
Setting this parameter to 0 automatically sets
the encoder resolution as the numerator.
(131072 for a 17-bit absolute encoder, or
10000 for a 2,500-p/r incremental encoder).
Note Set the electronic gear ratio within the
range of 1/100 to 100 times. A
parameter setting alarm (alarm code
93) will occur if the ratio is set outside
of this range.
Sets the denominator for the electronic gear
ratio.
Note Set the electronic gear ratio within the
range of 1/100 to 100 times. A
parameter setting alarm (alarm code
93) will occur if the ratio is set outside
of this range.

Sets the deviation counter overflow level.
The value will become saturated at
27
134217728 (= 2 ) pulse after multiplying with
the electronic gear ratio.
Setting this parameter to 0 will disable
deviation counter overflow.
Do not change.
