Speed reduction
ratio
Sets the speed reduction ratio when the rotation speed of the gearhead output
shaft is monitored.
The speed reduction ratio is calculated by multiplying a value in the "Speed
reduction ratio" parameter by that in the "Speed reduction ratio digit setting"
parameter.
The rotation speed of the gearhead output shaft can be checked on the monitor
of the
MEXE02
,
OPX-2A
, or RS-485 communication.

Speed increasing
ratio
Sets the speed increasing ratio when the increased rotation speed is monitored.
If the speed increasing ratio is set to other than 1, the speed increasing ratio is
prioritized.
The rotation speed of the gearhead output shaft is shown on the monitor of the
MEXE02
,
OPX-2A
, or RS-485 communication as a value calculated by multiplying
a value in the "Speed increasing ratio" parameter by a rotation speed.

Conveyor speed
reduction ratio
Sets the conveyor speed reduction ratio when the conveyor transfer speed is
monitored.
The conveyor speed reduction ratio is calculated by multiplying a value in the
"Conveyor speed reduction ratio" parameter by that in the "Conveyor speed
reduction ratio decimal digit setting" parameter.
The conveyor transfer speed can be checked on the monitor of the
MEXE02

increasing ratio is prioritized.
The conveyor transfer speed is shown on the monitor of the

selection
Sets the motor rotation direction.
(Sets the rotation direction when turning the FWD input ON if the "2-wire mode" is
selected with the "Operation input mode selection" parameter.

Calculation method for speed reduction ratio
To display the rotation speed of the gearhead output shaft on the
MEXE02
Set using the "Speed reduction ratio" parameter and "Speed reduction ratio digit setting" parameter.
Example)
When the speed reduction ratio 15 is set
Rotation speed
Set 150 to the "Speed reduction ratio" parameter and ×0.1 to the "Speed reduction ratio
digit setting" parameter.
15 that was calculated by the formula "150 x 0.1" was set.
At this time, one-fteenth speed of the motor rotation speed is displayed.
To display the conveyor transfer speed on the
MEXE02
Set using the "Conveyor speed reduction ratio" parameter and "Conveyor speed
reduction ratio decimal digit setting" parameter.
To display the conveyor transfer speed, calculate the conveyor speed reduction ratio
using the formula below and set the value in the "Conveyor speed reduction ratio"
parameter.
